3. Description of the projects planned within the Project and investments related to it.

Draft entitled .: "Modernization Swinoujscie‐Szczecin to a depth of 12.5 m" (hereinafter referred to as draft) of the third stage of the modernization Swinoujscie‐Szczecin (Fig. 1). This path ‐ currently holding a minimum depth of 10.5 me a minimum width of 90 meters ‐ runs initially Świna old bed, then two intersecting przekopami island of Usedom ‐ Channel Mielińskim and Piastowski Canal, next ‐ a deep gutter by the lagoon and enter the estuary section of the Oder.

The total length of Swinoujscie‐Szczecin is 67.7 km, counting from the head of the breakwater in Świnoujście in a southerly direction. It consists of a 16.5 km section of land within the islands of Usedom and Wolin, 19.5 km section of track by the lagoon, 8.5 km section of the Glen Odrzańska and the 23.2 km section of the Oder estuary.

Historically, the first shipping lane connecting the city located at the mouth of the Oder to the Baltic ran strait strange. In the thirteenth century, as a result of wars and carried silt Strange, shipping lane was transferred to the foam, which until the beginning of the eighteenth century. Was the only connection between Szczecin and the Baltic Sea. Swina Strait strait was then a very shallow, with many bends shallows. Świna same outlet to the sea divided the shoal of sand, dividing the trough into two branches.

The first attempts to adapt Świny for navigation taken in 1730. [76]. This work lasted until the late nineteenth century. Adverse navigation was very irregular and sinuous course Świna. In order to facilitate the movement of ships built between 1855 and 1880 ÷ current Piastowski Canal, digging the south‐eastern part of the island of Usedom. In the following years it made its extension ‐ Channel Mieliński.

Until World War depth Swinoujscie‐Szczecin for the entire route was 7.0 m. In 1928. Achieved throughout the depth of the waterway to 8.0 m, and 1939. ‐ 9,6 m. During World War II and in the post‐war seaway Swinoujscie‐Szczecin has significantly shallowness. Regular dredging works on the seaway began in 1949., In 1957 to obtain a depth of 9.6 m. Also in the following years, to allow entering the port of Szczecin increasingly larger units, works related not only deepening of the fairway, but its expansion.

Currently, the minimum depth Swinoujscie‐Szczecin is 10.5 m.

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

Since 2000. Fairway Swinoujscie‐Szczecin is subject to modernization. This upgrade is carried out in stages, as part of separate projects [24]. And yes:

in the years 2000 ÷ 2004 (Phase I) built a new breakwater at the exit Canal Piast Szczecin Lagoon and reconstructed sea defenses Piastowski Canal sections from km 16 + 034 to km 13 + 015 (east side) and from km 16 + 178 to km 12 950 (west side) Swinoujscie-Szczecin, adapting them to the track depth of 12.5 m;

in 2013 ÷ 2015 (Phase II) was reconstructed fortifications Boundary Channel Piastowskie sections from km 13 + 015 to km 9 + 000 (East): and from km 12 + 950 km 9 + 000 (west side) Swinoujscie Szczecin and remodeling and construction of revetments Channel Mielinski sections from 9 km to 000 km + 5 + 400 (east): and from 9 km to 000 km + 5 + 043 (west side) Swinoujscie‐Szczecin. The fortifications were adjusted to track the depth of 12.5 m. Additionally, within the investment eliminated venturi hydraulic km 8 + 050 fairway and converted, or eliminated built quays portion located within the above‐mentioned. channels.

This Motion of stage III modernization Swinoujscie‐Szczecin. Its aim is to obtain a minimum depth of 12.5 meters along the entire length of the track. This project includes the execution of the following measures [58]:

deepening of the fairway section of 5,280 km to 16,500 km (Mieliński channel and channel Piastowski) to a depth of 12.5 m behavior defined in step II modernization waterway width in the bottom;

deepening of the fairway for the section from 16,500 to 67.700 km to a depth of 12.5 m (currently 10.5 m) and increase its width in the bottom of 100 m (currently 90 m) on the straight sections and the curves at 150 m;

modernize three turntables ship: – Police turntable (in the vicinity of the port of Police) measuring axis of 825x350 m, – Isthmus Orla turntable with a diameter of 362 m. – Grabowski turntable channel with a diameter of 220 m;

mijanki embodiment vessels Szczecin Lagoon between the second and third gate Lane, a width of 250 m and a length of 5 km additional segments transition approx. 800 m at both ends, allowing a smooth and safe passage of large vessels (group 1) units of other size categories;

adjacent to the turntable embodiment Police mijanki Police a width of 220 m and a length 1.6 km, allowing large ships to pass each other with small and very small and departing from

construction of revetments;

Established slope slopes gutter waterway on its various sections are close to the averaged slopes of the currently existing there. The Project adopted the general principle that the slope will not be formed and strengthened everywhere where there is no absolute need to protect the edges and areas of natural land or existing hydraulic structures [25]. In Tab. 1 shows the place in which the slope and depth of the enlarged the fairway or upgraded turntables will interfere with the natural (undeveloped) coastline the Oder River (or the associated channel) between the Police, and the port in Szczecin ‐ so. boundary collisions. On these sections, the retrofitting fairway can be expected subsidence trough banks and silting. – Dig Mieleński ‐ Channel Grabowski, in which the rotating modernized vessels.

Modernized rotating Isthmus Orla interferes with aqueous shunt connecting piercing Mieleński with lake Dąbie called Eagle Isthmus and chamfer forces the northern head of the island Ostrow Grabowski (at the extreme approx. 150 m). Environmental considerations (water exchange between basins, the possibility of runoff of ice) require that the width of the current Isthmus and depth of the Eagle. This means the need for appropriate security Radolin southern tip of the island and the northern promontory of the island and the United Kepa performance in the above. fistula underwater buttresses from the edge of the fairway for a natural depth of the basin ‐ formed with a slope of 1: 3 and strengthened riprap to geotextile. According to [25] spit island Radolin be strengthened by means of anchoring steel sheet piles of oczepami ferroconcrete. The level of the bottom of the cofferdam from the fairway will be ‐ m 6.0 Rel. Cr. Escarpment before cofferdam ‐ a projected slope of 1: 3 ‐ will be strengthened riprap on the geotextile. The cofferdam will pass to the strengthening of boundary type nabrzeżowego. Spit Island United Kepa and receding shore of the island Ostrow Grabowski will be protected slope with a slope of 1: 3, fortified riprap on gewłókninie prism and ending at elevation +1.0 m resp. Cr.

According to [27, 58] the total length of the collision boundary that are not protected by fortifications is 5.585 kilometers. The total length of the edge collision, which will be undergoing umocnieniowe prevent landslides shore and silting fairway is 1.141 km.

reconstruction of existing embankments (HUK strengthening wharf, quay Nautical, navigational aids Base quay, the quay Gnieźnieńskie);

The Project is assumed that the intersection of the plane of the slope of the gutter waterway plane of acceptable depth at the building site HDOP hydro at a distance from the edge less than approx. 1.5 times HDOP poses a threat to the structure. This situation applies covers three piers on the west bank of the Oder, ie. HUK waterfront, waterfront wharf Sailing and Navigation Databases Labeling (OPD) and Gniezno waterfront on the island of Ostrow Grabowski. In [25] presented three variants of securing these wharves.

In one of the variants in the case of piers HUK, nautical, BON work includes: forming the slope of the track with a slope of 1: 3 and strengthening the riprap to geotextile, to strengthen the foot of the slope by filling the bottom of the track ‐ in a strip width of approx. 10 m ‐ rubble to a depth of 14.0 m scoring sheet pile within 2Hdop and before execution of said wall corresponding overhead of rubble or the support structure of the mattress gabion possible execution filling soil between the bank and the wall sealed to the level HDOP, deletion or truncation of the wall tight.

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

In the case of quay Gnieźnieńskie, due to the proximity of the turntable the ship and which can perform there intensive water movement, caused by a push / pull of the masses of water through the hull of the rotating vessel and strong currents screwed (tug, ship) are designed forming the slope of the track with a slope of 1: 3 to reinforce its riprap on the geotextile. Strengthening will be ended horizontal flange width. 2 m, a depth limit on the crown at the quayside, ie. On the ordinate m 7.0 Rel. Cr. Grading rate will be enhanced by filling the bottom of the track ‐ in a strip width of approx. 10 m ‐ rubble to a depth of 14.0 m [25].

construction of new or expansion of existing fields refulacyjnych;

When intended to deepen and widen the fairway is extracted approx. 23 212 thousand. m3 dredged materials [58]. While it will be uncontaminated dredged materials, its storage will take place in the designated fields and suitably prepared spoil (refulacyjnych). The Project [28, 39] is considering the construction of: – a large, polygonal boxes adjacent islands Chelminek (old field silting Maritime Office), located in central‐western area of flooding on the east side of the fairway. – a large island, located in central‐western area of flooding on the east side of the fairway. – three islands located in the central zone of the Lagoon ‐ two islands on the eastern side of the fairway and one on the west.

adapting an existing navigational aids to the new geometry fairway meaning moving dolphins 30 defining the eastern edge of the fairway km from 55.950 to 67.525 km path. Because the axis of the fairway will remain essentially unchanged, it is not expected to change the location of the other characters fixed.

Projects related to the project ‐ although planned as a separate investment (hereinafter referred to as accompanying investments) [77, 84] ‐ are:

Deepening Swinoujscie-Szczecin on the section from km 0.000 to km 3.100 to a depth of 14.5 meters (currently 14.3 m), which will be executed within the statutory activities of the Maritime Office in Szczecin;

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

As approved by the Council of Ministers and published in 2011. Plan of water management in the basin of the Oder [33] in relation to the JCWP Estuary Świna JCWP and Szczecin Lagoon introduced, pursuant to art. 4 (4) ‐3 WFD, the derogation from the requirement to achieve good ecological potential and good chemical status by 2015. It was argued that, due to natural conditions six years is too short a period to be able to improve the state, even the complete elimination of pressure. These are bodies of water contaminants from the receiver because a large area of land and their state is directly dependent on both the status of inland waters, as well as the limitation of the pressure in the interior.

Derogation from the requirement to achieve good ecological potential and good chemical status by 2015 have also been introduced with regard to the JCWP JCWP Odra from Párnica to the mouth. In [33], the following reasoning: "Because of the planned activities of the investment resulting in changes in physical characteristics JCW, for higher social aims, ie. Flood protection, it is impossible to achieve by JCW environmental goals."

According to the provisions of the Plan of water management in the basin of the Oder [33] environmental objective for groundwater bodies PLGW67002 is to maintain good quantitative and chemical status.

Within the limits of the above. water bodies are protected areas within the meaning of the Water Framework Directive, mentioned in the Schedule of bodies of surface water intended for recreational purposes, including bathing (referred to in Art. 113 paragraph. 4 point 2 of the Act of 18 July 2001. ‐ Water Law2), In Schedule of bodies of water intended for the abstraction of water for public supply of water intended for human consumption for drinking (referred to in Art. 113 paragraph. 4 point 1 above. Act) and in the Schedule of areas intended for the protection of habitats or species laid down in the nature Conservation Act, for which the maintenance or improvement of water is an important factor in their protection (referred to in art. 113 paragraph. 4 point 6 above. Act).

The currently applicable Plan of water management in the basin of the Oder [33] environmental objectives for protected areas have not been increased. The rationale is often higher requirements with respect to the limit values of indicators of water quality for a good state / ecological potential than served in the acts governing law requirements for water status within these areas, in the case of Natura 2000 areas ‐ the lack of protection plans or plans of protection tasks.

Under Article. 38f Water Act for the purpose of environmentally protected areas is to achieve the standards and objectives of the specific provisions under which those areas have been created, as long as they do not contain in this respect different provisions.

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

In 2013. On request of the National Water Management was realized for the update management plans for the river basin in Poland work entitled .: Determining the environmental objectives for surface water bodies (JCWP), underground (groundwater bodies) and protected areas [62]. As part of this work was developed methodology for determining the manner of determining the environmental objectives for water bodies, taking into account ‐ in the case of the existence within their borders protected areas ‐ a condition To use the most rigorous or indicate additional targets. Based on this methodology, using the results of evaluation of the JCWP for the years 2010 ÷ 2012 made by the Chief Inspectorate of Environmental Protection and the results of the assessment of groundwater bodies made by the Polish Geological Institute ‐ National Research Institute, have been set back environmental objectives for all water bodies and summarized them in a standardized cards water bodies (JCW). These cards were used in the renovation plans for the ongoing management of the river basin and made available to the public consultation, together with draft these documents.

Derived from [81] for the JCW card: surface water body PLTWIWB7 Mouth Świna surface water body PLTWIWB8 Szczecin Lagoon, surface water body PLRW6000211999 Odra from Párnica to the mouth, bodies of groundwater PLGW60001, PLGW60004, PLGW60007, They are, respectively, Annex 1 ÷ 6 hereto. In accordance with the

above. cards JCW environmental objectives are:

in the case of surface water body PLTWIWB7 Estuary Świna:  achieve good ecological potential,  achieve good chemical status

in the case of surface water body PLTWIWB8 Szczecin Lagoon:  achieve good ecological status,  achieve good chemical status  maintain or restore a favorable conservation status listed in the card depending on the subject matter in waters designated protected areas;

in the case of surface water body PLRW6000211999 from Párnica to Measles the mouth:  achieve good ecological potential and the possibility of migration of aquatic organisms  achieve good chemical status  maintain or restore a favorable conservation status listed in the card depending on the subject matter in waters designated protected areas;

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

in the case of a body of groundwater PLGW60001:  the achievement of good quantitative status,  achieve good chemical status  the quality of underground water, which is charged to the needs of public water supply intended for human consumption should not deteriorate.

in the case of groundwater bodies PLGW60004 and PLGW60007:  maintaining a good quantitative status,  maintaining good chemical status  the quality of underground water, which is charged to the needs of public water supply intended for human consumption should not deteriorate.

The card JCWP Mouth Świna indicated no areas for the protection of habitats or species for which the maintenance or improvement of water is an important factor in their protection.

The Szczecin Lagoon JCWP tab lists the following protected areas designed to protect habitats or species for which the maintenance or improvement is an important factor in their protection:

According to the developed in the [62] the method for setting the environmental objectives for water bodies environmental objectives protected area identified on the JCW apply only to those sections of the body of water in which these areas are located, and not the entire body of water. These objectives may, however, have implications well beyond the protected area to which they apply, but only to the extent that is necessary for their achievements in this area.

It should be emphasized that contained in the above. JCW card information, in particular on exemptions from the environmental objectives, subject to certain adjustments yet. The process of public consultation draft renovation plans for management of river basin ended on 22 June. The final versions of these documents, valid for the years 2015 ÷ 2021 are to be ready by the end of the year [81].

4.1.2. Characteristics JCW.

4.1.2.1. JCWP Świna Estuary.

Heavily modified water bodies in the category of surface waters Estuary Świna a narrow strip of the Pomeranian Bay waters adjacent to the island of Usedom from the state border to the central breakwater (formerly the East) in Swinoujscie, a width of 1 nautical mile and the average length of approx. 4.8 km (Fig. 2). The total area of 8.93 km2 is JCWP.

Within Pomeranian Bay transformation takes place, and river water take place by intense impurity distribution of the basin worn Oder. The yield northern Gulf, separating it from the waters of the Bornholm Basin is a line drawn from Cape Arkona (Rügen) to the lighthouse Gaski, located approx. 20 km east of Kolobrzeg. Pomeranian Bay area is approx. 6 thousand. km2 and the average depth of slightly more than 13 m. In the middle of the bay there is a shallow water (Shoal of Odrzańska), where the depth of the sea does not exceed 8 m. The bottom contours defining the depth of ten meters ‐ except for the region of the mouth of the odd extends approximately parallel to the coastline, at a distance of 1 ÷ 2 mm. It is assumed that the average salinity of the bay is 7.5‐ 8.0 ‰ [36]. Ocean currents in the Pomeranian Bay are dependent on long‐lasting winds and mostly are directed to the east. Their speed along the coast reaches 2 knots (approx. 1 m / s) within 3.5 mm from the edge [19].

Under JCWP Świna Estuary is regularly dredged fairway floating units providing access to the ports of Swinoujscie and Szczecin.

4.1.2.2. JCWP Szczecin Lagoon.

Characteristics of hydrographic. The heavily modified body of transitional waters (JCWP) PLTWIWB8 Szczecin Lagoon includes, among others water (Fig. 3): Grand Lagoon, part of the Gulf Nowowarpieńskie Polish, Glen Oder, lakes Wicko Big, Small Wicko Lake and water strait Świna, including Old Swina, Piastowski Canal and Canal Mieliński.

The total area JCWP Szczecin Lagoon is approx. 407.28 km2, the length of the coastline of this part of the water is approx. 321.76 kilometers.

Szczecin Lagoon is a large reservoir with an area of przymorskim approx. 687 km2, average depth of 3.8 mi average volume of approx. 2.58 km3. Through the middle of the Lagoon, at the border of the natural hydrogeological, the state boundary dividing the area into Polish ‐ Grand Lagoon and part of the German ‐ Little Lagoon.

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

Szczecin Lagoon is powered mainly waters from the catchment area of the Oder. The share of the waters of the Oder approx. 97% of the total inflow of water into the lagoon. Other major tributaries are: Gowienica, Foam, Swiniec, Wkra Wołczenica and Zarow.

Szczecin Lagoon is separated from the Pomeranian Bay and the islands of Usedom and Wolin connected with the sea by three narrow and elongated straits: Foam (Peenestrom) to the west (Germany), Świna between the islands of Usedom and Wolin, and strange in the east. Through these straits is held bi‐directional exchange of waters between the Lagoon and the sea. The movement of water in the straits has the characteristics of different pulsation frequencies [76]. The estuary section Foam flow direction changes are frequent and evenly distributed throughout the year. The strait Świna in the autumn‐winter season flows are characterized by a high frequency of changes, and in the spring‐summer season there are long periods of continuous outflow of water from the lagoon to the sea, occasionally interrupted inflows. The strait strange, throughout the year there is a clear advantage outflow of water towards the sea.

Currently, the main connecting Szczecin Lagoon from the Baltic Sea is Świna strait, which runs the fairway Swinoujscie‐Szczecin. Previously, a more important role in the exchange of water between the Lagoon and the Baltic Sea Foam meets the strait, which led main shipping route for ships bound for the port of Szczecin. Świna estuary was shallow and the sand content constantly. The situation changed only after the construction of the Piast Canal.

Currently it is estimated from pigs flows total approx. 78% of the water from the lagoon (including 47% Canal Piastowskim and 31% Old swine) foam, ‐ approx. 14% and the least strange ‐ approx. 8% [76].

Characteristics of hydrological and meteorological. Water levels and flows in the JCWP Szczecin Lagoon are formed on one side by the size and nature of the Lagoon tributaries of the river, mainly from the catchment area of the Oder, on the other ‐ by sea level changes in the Pomeranian Bay and the effect of wind on the water bodies.

Simultaneous overlapping influences odmorskich and runoff from the catchment area of the Oder makes the area JCWP Szczecin Lagoon can not talk about the interdependence between states and the water flows. Hydrological characteristics of the body of water so it can be based only on the water levels.

One of the basic factors determining the hydrodynamics JCWP Szczecin Lagoon is the wind. Variable complex topography and hydrography above. body of water, the presence of two large bodies of water, ie. the Szczecin and the Baltic Sea, for free movement of air masses makes the wind conditions within JCWP are varied. A significant variability in the occurrence of winds the study area is also observed in different seasons. In the spring and summer it is often winds from the northern sector (NE, NW and N), and in the autumn and winter are a step ahead wind direction southern especially SW and S. seasonality occurrence of winds associated with modulation of the Baltic Sea and particularly the variation in temperature between the land and sea. Therefore, in the spring and summer circulation is dominated by a supercharged,

The characteristics of the wind conditions within JCWP Szczecin Lagoon determined on the basis of two meteorological stations, ie. Swinoujscie thinning and reported in [35].

Statistical analysis of wind conditions occurring in Świnoujście multi‐year period 1970 ÷ 1995 indicated that [35]:

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

in the medium most frequent wind direction W (20.62%), SW (19.26%) and S (16.27%) and the least with the direction N (7.39%) and NW (7.42% ) Total silence accounted for 2.90% of all observations, which gives almost 11 days a year with no wind, strong winds exceeding 5O Beaufort (speeds above 10 m / s) blew average of 13 days in the year, representing 3.57% of the total observation the annual average wind speed Swinoujscie was 3.92 m / s, characterized by the highest average speed winds from the northern sector N (5.6 m / s), NE (5.4 m / s) NW (5.1 m / s); the weakest direction winds occur southern S (3.0 m / s) SE (3.3 m / s) and SW (3.3 m / s).

Statistical analysis of wind conditions occurring in the thinning multi‐year period 1970 ÷ 1988 indicated that [35]:

in the middle of the most frequent wind direction SW (20.81%), NW (14.90%) and W (13.86%) and the least likely of the directions E (3.79%) and S (8.99% ) Total silence accounted for 6.14% of all observations, which gives 22.5 days a year with no wind, strong winds in excess of 50 on the Beaufort scale (for speeds above 10 m / s) blew average of 12.7 days in the year, accounting for 3.48% of all observations, the annual average wind speed Trzebiez was 4.69 m / s, characterized by the highest average speed winds from the northern sector N (5.6 m / s), NW (5.4 m / s) W (5.2 m / s); the weakest winds occurred from the south: S (4.4 m / s).

Comparison of the frequency direction and wind velocity and average wind speeds of individual fields designated Swinoujscie thinning and graphically illustrated in Fig. 8 and 9.

Operation of the wind on the surface of Szczecin Bay cause its height differences, without changing the total weight of the water in the tank. The results of the model calculations [76] indicates that at very high wind speeds of about 20 m / s, the difference in water levels in the lagoon on the windward side and the leeward side is maximum 50 cm. The winds of velocities up to 10 m / s will result in much smaller difference in water levels in the Lagoon not exceed several centimeters. Despite almost twice the acceleration, winds latitudinal direction (i. W and E) deniwelują surface of the body of water to a similar extent as the longitudinal direction of the wind (ie. N and S). Decide on the bathymetry of the basin, especially in the direction of extension of latitudinal belt greatest depth,

Wind impacting directly on the surface of the water in the form of wind friction also causes waving. Wave height of the wind depends on three main factors: wind speed and direction, duration, and run the wave. Maximum wind waves Szczecin Lagoon observed with winds from the west (W), then the directions E, SE and SW, and the lowest ‐ the directtions N and SW (May). Similarly, the highest average wave perriods arise when the western winds, the smallest ‐ with winds from the northern and south‐western. The maximum measured wave height were 2.0m brine [76], in the summer waves are generally less than 1.4 m. 45

Wind Ripple caused by moderate and strong winds ‐ due to the shallowness of the lagoon ‐ and reaches the bottom of the water molecules in motion wave abduct sediments, float it and move with the currents. According to [76] during periods of storm water molecules orbital velocity at a depth of 6.0 m may reach up to 1 m / s. Wind wave phenomenon is accompanied by the so‐called. wave currents. The speed of these currents are generally small ‐ to a depth of 6.0 m is approx. 0.05 m / s, but at smaller depths of bottom current speed waveform can be much higher [76].

Characteristics of hydrodynamic. Complexity of the relationship between the drivers of the hydrodynamics JCWP Szczecin lagoon and its complicated system hydrographic make the determination of the flow conditions in the specific sections requires the involvement of appropriate numerical or hydraulic models.

From the point of view of this report, concerning the impact assessment of the Project entitled. "Modernization Swinoujscie‐Szczecin to a depth of 12.5 m" For water protection JCWP Szczecin Lagoon important characteristic is the hydrodynamic conditions occurring both in the strait Świny and Szczecin Lagoon.

The basic size dominate the dynamics of the flow in the carpal Świny is the size and direction of the difference of water levels (bleed) between its ends. The results of long‐term observations carried out in the strait Świny indicate that the frequency of appearance of the positive bleed (drain into the sea) is greater than the negative (inflow from the sea to the Lagoon) and is 56 ÷ 64% [67]. In subsequent years, the ratio of the inflow and outflow of water in the strait depends primarily on the size of the total flow from the top of the Oder catchment. High flows associated wezbraniom on the Oder are reflected in the inhibition of the influx of water from the sea to the lagoon after about 1 ÷ 2 months.

Analysis of bleed in the strait Świny indicates that the most they vary in the range of ‐4 to 5 cm. On average, higher bleeds observed more frequently in the autumn and winter than in spring and summer. Given [67] that in the multi‐year period 1948 ÷ 1957 major bleeds were:

in autumn and winter period for discharge into the sea: 108 cm, the inflow of the Lagoon: ‐98 cm in the spring and summer for the outflow to the sea: 77 cm, for the influx of the Lagoon: ‐60 cm.

Based on the test results ‐ using the results of measurements made in the field and hydraulic models and the results of calculations carried out on numerical models ‐ have been developed at the Institute of Hydraulic Engineering Sciences in Gdańsk [67] curves illustrating the dependence of the flow rate in each channel strait Świna the difference in water level Szczecin Lagoon (Thinning) and the Pomeranian Bay (Swinoujscie). These relationships have been determined for steady flow conditions, which requires the maintenance of a constant

difference of water levels at the ends of the strait for a long time. Such situations are quite rare, therefore read the above. flow rate curve should be considered approximate. It should be emphasized that the unsteady flow conditions, eg. During storm surges in flow channels Piastowskim Mielińskim and are often much higher (up to approx. 35%) than that of a flow curves developed for fixed traffic conditions.

Determined by the IBW PAN ‐ based on a mathematical model calculations taking into account the conditions of morphometric the years 1968 ÷ 70 [67] ‐ the above. curves for the Piast Canal and Canal Mielinski shown in Fig. 10.

Analysis of these curves shows that:

at the same absolute values fall between the Szczecin Lagoon and the Gulf Pomeranian flow rate at the outlet of water from the sea it is greater than the inflow of water from the sea to the Lagoon - 6 ÷ 8% in the case of Channel Piastowskie and about 2 to 3% more in the case of Channel Mielinski, the most frequent strait Świny low heads (-4 to 5 cm) flow in the Channel Piastowskim traffic conditions set ranges from approx. -300 m3 / s to approx. 450 m3 / s respectively Channel Mielińskim from approx. ‐270 m3 / s to approx. 350 m3 / s, low heads reaching maximum of 1.5 m, an estimated flow Channel Piastowskim may be approx. 3200 m3 / sec for discharge into the sea and approx. -2900 m3 / s in the case of flow into the lagoon; Channel Mielinski for these flows may be respectively: approx. 2,800 m3 / s and approx. ‐2700 m3 / s.

Szczecin Lagoon is a large but relatively shallow tank, which makes it particularly susceptible to circulate water mass induced by the wind. An important role in shaping the lagoon water circulation systems also play: inflow of water from the catchment area of the Oder, two‐way flow of water in the straits connecting the lagoon with the Pomeranian Bay and bathymetry of the lagoon.

Landmarks in the Szczecin is the presence of density‐stratified flows, which mixing occurs to fresh water mainly carried out by the Oder salt sea water. Due to the presence of a deep trough fairway Swinoujscie Szczecin mixing processes and exchange of water in brine they are very intense. After wezbraniach strong storm when there are rapid flows of salt water from the sea, and in the deeper parts of the fairway recorded salinity water salinity corresponding Pomeranian Bay ie. ‰ 5 ÷ 7. Range wedge of salt water reaches an average of up to cross in Police (ie, 50 km from Swinoujscie), and water with a salinity of 1.5 ‰ is observed even at the height of the Oder River in Szczecin.

Research on currents made by the Szczecin Lagoon Majewski in the 60s of the twentieth century. [67] indicate that they are characterized by relatively low‐speed measuring an average of 0.05 m / s and a very low stability. Higher average speed occurred only at the entrance to the canal Piastowskie ‐ approx. 0.20 m / sec at the mouth of the Old Świny (0.09 m / s) and at the mouth of the Oder (0.085 ÷ 0.11 m / s). It should be stressed that the highest measured speed currents were greater at the bottom (0.30 m / s) than at the surface (0,25 m / s). The surface layer is highest velocity along the foot of the slopes shallows eastern and northern reservoir in the outlet of the channel and the Old Piastowe Świny, while at the bottom of the greatest speed occur along the fairway, and connecting the gutter Small and Big Lagoon [67].

The observed large variation in current direction indicates a large movement of the instability of water within the Lagoon. Among the areas with a highlighting clear to the predominant direction of current Majewski [76] has distinguished water path Swinoujscie‐Szczecin predominantly inflows from the sea bottom to the reservoir and a part of the reservoir between the water line and the south‐western shore of the reservoir with a predominance of current drain.

The study water circulation in the Szczecin Lagoon ran in the 80s of the twentieth century. Water Institute of Building Sciences (IBW PAN) [67]. The results of field measurements and calculations on hydraulic model indicated that the circulating water systems in the Szczecin Lagoon depend primarily on the strength and direction of the wind. The authors [67] provide some general features forming system for circulating brine ‐ schematically them Fig. 11. In both parts of Szczecin Lagoon ‐ ie. In the Large and Small Lagoon ‐ there tends to be two water circulation system and which direction It depends primarily on the direction of the wind and to a lesser extent on the direction of flow in the Strait Świna.

The length of the courses relevant JCWP is 29.047 kilometers [32, 78].

Measles is the second largest Polish river. Its total length is 840.90 kilometers, of which the Polish borders is 726.48 kilometers. Odra river basin with an area of 119 thousand. km2 characterized by a marked asymmetry of ‐ the surface ratio of the basin left to right is 3: 7. Sources are in the Odra Odra Mountains in the Czech Republic. Odra Odra flows into the Glen which is part of the Szczecin Lagoon, combined with the Pomeranian Bay three straits Świna, strange and Foam.

Hydrological and hydrodynamic conditions in the Odra JCWP from Párnica to the mouth are the result of interactions such phenomena as:

 variable sea states causing backwater odmorskie,  variable cash flows from the top of the river causing changes in water levels of niżówkowych to flood  wind turbines causing backflow causing additional podpiętrzenie (in the case of northern winds) or the lowering of water (in the case of wind Southern)  atmospheric pressure changes associated with the passage depressions atmospheric pressure causing transient surges (INFERENCE waves)  human activity is changing bathymetry of the river and its hydrographic system.

Simultaneous overlapping influences odmorskich and runoff from the catchment area of the Oder makes the area of the mouth of the Oder can not talk about the interdependence between states of water and flows, Characteristics of hydrological JCWP Odra from Párnica to the mouth based so it can only on the states of the water and not on the flows.

Wodowskazowym section representative for ‐ located within the area JCWP Odra from Párnica to the mouth of Swinoujscie‐Szczecin post wodowskazowy Szczecin Long Bridge is located in the 739.9 km of the river Odra (according to [1, 20] 22.85 km), belonging to the network observation of the Institute of Meteorology and Water Management Branch in Gdynia.

4.1.3. Qualification in terms of hydro‐morphological changes.

4.1.3.1. JCWP Świna Estuary.

JCWP Estuary Świna at the stage of implementation of the Water Framework Directive and the development of the first water management plans for the river basin was considered heavily modified [33]. Carried out in 2012. By the Regional Water Management Board in Szczecin verification designation of heavily modified and artificial transitional and coastal waters in the area of its operation, this qualification maintained [32, 78].

Ww. verification has been made on the basis of carried out by the Institute of Meteorology and Water Management, National Research Institute, Maritime Branch in Gdynia work entitled .: Development of the methodology to verify the designation of heavily modified and artificial transitional and coastal waters (hereinafter Methodology) [31].

According to the methodology in [70] for JCWP Estuary Świna ‐ as well as for other water bodies transitional area of operation RZGW in Szczecin ‐ the first hydro‐morphological changes were identified and then evaluated the significance of these changes and their impact on ecosystems.

Carried out for the area of transitional measures in Szczecin RZGW expert assessment of the significance of the identified hydrological changes and their impact on ecosystems did not give rise to these waters because of this show as heavily modified. Within the above. Although there has been a change of water flow distribution between the Oder three strait connecting Szczecin Bay of Pomeranian Bay in connection with the adaptation Świny for shipping. However, work in this direction were spread out in a long time. It made changes in hydrological conditions ‐ as well as morphological and chemical ‐ in these areas followed in an evolutionary manner, allowing ecosystems to adapt to them in the same way. Completion of the above. work took place over a century ago, and the available data from the last century do not suggest that during this period there have been significant changes in hydrology.

Morphological changes in the estuary JCWP Świna are associated with both hydro‐technical infrastructure, as well as the work they carry out concerning the maintenance and dredging fairways.

According to the Methodology of assessment of the significance of the above. morphological changes and their influence on the estuary ecosystems Świny was made using the impact indicator WskWp described by the following formula:

4.1.4.2. JCWP Szczecin Lagoon.

JCWP state Szczecin Lagoon in 2012. Was classified as poor. [72] His assessment was carried out by WIOŚ in Szczecin, according to the Regulation of the Minister of the Environment of 9 November 2011. On the classification of surface water bodies and environmental quality standards for priority substances10.

Classification of ecological potential JCWP Szczecin Lagoon in 2012. Was made on the basis of [71]:

the results of research conducted in 2012. in the monitoring of the operating positions E, C, H, SWR; and ‐ based on the principle of inheritance ‐ on the basis of: the results of studies of the biological elements of 2011. under the surveillance monitoring positions F, B2, JWW (and in the case also of the macrozoobenthos H) Research fish fauna of 2011 r., test results physicochemical elements characterizing the physical state, oxygen and organic contaminants and nutrient conditions from 2011. from positions F, B2, JWW, the results of the testing of substances that are particularly harmful to the aquatic environment of priority in five positions of surveillance monitoring in 2011., i.e. .: C, H, F, B2, JWW.

It was found that almost all positions of the chlorophyll concentration "a" and the value of which is determined for benthic makrokręgowców multimeric index B are in the fourth or fifth quality class. Exceptions in this regard are the position E and SWR, respectively, in which the average concentration of chlorophyll "a" and the index B multimetryczny limits potential moderate (Class III quality). Moderate ecological potential of the waters of the Szczecin Lagoon evaluation results indicate the fish fauna in the study by the Sea Fisheries Institute entitled .: Evaluation of the ecological status of transitional waters for the year 2011. Pursuant to the Regulation of the Minister of the Environment of 9 November 2011. On the classification of surface water bodies and environmental quality standards for priority substances. When assessing the ecological potential classification they should be treated as macroalgae and angiosperms. However, due to the lack of recognition of the prevalence of these organisms in the waters of the Szczecin Lagoon, this item was omitted from the assessment. Taking into account the average of the seven positions of the measurement value of the concentration of chlorophyll "a" and the index B ‐

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

of respectively 38.35 and 2.05 mg / l ‐ the potential ecological JCWP Szczecin Lagoon in the field of biological elements has been classified as weak.

In accordance with the principle that a body of water, not assigned on the basis of reviewing the terms hydromorphological as artificial or modified is suitable in the range of hydromorphological elements class I, whereas the body of water designated as artificial or modified class II potential ecological JCWP Szczecin Lagoon on the elements hydromorphological He has been recognized as good.

Ecological potential JCWP Szczecin Lagoon in the field of physico‐chemical elements was assessed as less than good. Such an evaluation decided to cross the border of good status of the following indicators: the transparency of water, the content of total organic carbon (TOC) and ammonia nitrogen and water oxygen supersaturation recorded. Regarding test in 2011. For the five measurement positions Szczecin Bay (C, H, F, B2, JWW) 11 indicators from a group of substances that are particularly harmful to the aquatic environment, no exceedances of the limit values for good quality.

Evaluation of chemical JCWP Szczecin Lagoon is fully inherited from 2011. This assessment was based on the results of the part of the monitoring diagnostic testing of all the indicators listed in Annex 9 to the Regulation of the Minister of the Environment of 9 November 2011. On the classification of uniform bodies of surface water and environmental quality standards for priority substances in water samples collected twice during the season test in five positions: C, H, F, B2, JWW [40]. After verification of test results were excluded from the evaluation indicators for which the limit of quantification than 100% of the most stringent limit value, and which also occurred at concentrations below the detection limit of the analytical method (i. Diuron, endosulfan, heksachlorocyklobutadien, nonylphenols, simazine). The evaluation included, however, tributyltin compounds, and brominated diphenylethers, for which the detection limit is also exceeded 100%. These indicators, however, occurred in concentrations above the limit of quantification.

Chemical status JCWP Szczecin Lagoon was assessed as less than good. Such an evaluation chosen to exceed the average annual brominated diphenyl octylphenol and the values of average and maximum tributyltin compounds [40].

4.1.4.3. Measles JCWP from Párnica to the mouth.

Measles state JCWP from Párnica to the mouth in 2012. Skwalifikowany was as bad [72]. His assessment was conducted by the Regional Inspectorate of Environment Protection (WIOŚ) in Szczecin, according to the Regulation of the Minister of the Environment of 9 November 2011. On the classification of surface water bodies and environmental quality standards for priority substances on the basis of the results of research conducted on three measuring stations (Fig. 12):

 Measles Zachodnia‐ base UMS (Szczecin) ‐ hereinafter referred to as OP1,  Western Odra ‐ Long Bridge (Szczecin) ‐ hereinafter referred to as OP2  Oder ‐ estuary to Glen Oder (Police) ‐ hereinafter referred to as OP3.

In accordance with the above. Regulation ‐ as with the current Regulation of the Minister of Environment of 22 October 2014. ‐ in the case of surface water bodies, such as JCWP Odra from Párnica to the mouth (ie. the river designated as heavily modified) indicators of water quality serving the classification of ecological potential are :

in terms of biological elements:  phytoplankton (index fitoplanktonowy ifpla)  macrophytes (makrofitowy index river)  benthic macroinvertebrates (only element taken into account in the assessment under the Regulation of the Minister of Environment of 22 October 2014. ‐ indicator wielometryczny MMI_PL)  fish fauna (only element taken into account in the assessment under the Regulation of the Minister of Environment of 22 October 2014. ‐ indicator IBI);

on the elements hydromorphological:  with respect to the hydrologic regime: the number and growth of water flow connection to the groundwater.  with regard to the continuity: the number and type of barriers, to ensure a transition to aquatic organisms,  in relation to the morphological conditions: river depth and width variation, the structure and the channel substrate, the structure of the coastal zone, the rate of power;

in terms of physicochemical elements:  as indices characterizing the physical state of the water temperature, total suspension.  as indices characterizing the oxygen and organic contaminants: dissolved oxygen, five‐

day biochemical oxygen demand BOD5, Chemical oxygen demand COD‐Mn, total organic carbon, the chemical oxygen demand COD Cr‐

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

 as indices characterizing salinity conductivity at 20 ° C, sulfates, chlorides, calcium, magnesium, total hardness,  as indices characterizing the acidity: pH, total alkalinity,  as indicators characterizing the nutrients: nitrogen, ammonium, Kjeldahl nitrogen, nitrate nitrogen, total nitrogen, phosphate, total phosphorus, as especially harmful to the aquatic environment (specific impurities synthetic and non-synthetic) formaldehyde, arsenic, barium, boron, chromium, hexavalent chromium general, zinc, copper, phenols, volatile (phenol index), hydrocarbons of petroleum (index mineral oil), aluminum , free cyanides, cyanide-related, molybdenum, selenium, silver, thallium, titanium, vanadium, antimony, fluoride, beryllium, cobalt, tin.

Made in 2012. Phytoplankton and macrozoobenthos studies have shown that the biological elements are respectively II and class IV water quality. While other biological elements, ie. Macrophytes and fish species were not tested. On this basis, the potential ecological JCWP Odra from Párnica to the mouth in the field of biological elements was regarded as weak.

In accordance with the principle that a body of water, not assigned on the basis of reviewing the terms hydromorphological as artificial or modified is suitable in the range of hydromorphological elements class I, whereas the body of water designated as artificial or modified class II ecological potential JCWP Measles from Párnica to the mouth of hydromorphological elements range was assessed as good.

Ecological potential JCWP Odra from Párnica to the mouth in terms of physico‐chemical elements has been assessed as good. Such an evaluation water potential decided the results of the chemical oxygen demand COD‐Mn, Kjeldahl nitrogen and alkalinity.

Based on the above. findings ecological potential JCWP Odra from Párnica to the mouth was assessed as weak [71, 79].

JCWP chemical status was regarded as less than good. It decided to exceed the environmental quality standards established for tributyltin compounds.

The latest available results of water JCWP Odra from Párnica to the mouth relate to 2013. And comes from the position of Western Odra ‐ Base SUM (PO1). They do not change the previous assessment that JCWP.

Test results of water quality of the Oder in the years 2012 and 2013 are presented in tab.15, specifying limits for individual indicators in accordance with the Regulation of the Minister of the Environment of 22 October 2014. On the classification of surface water bodies and environmental quality standards for substances priority.

4.2. STAGE II.

4.2.1. Identification of the factors of the Project on water quality elements.

As agents of the Project and related projects that may affect the elements of the water quality of surface water bodies Świna estuary, Szczecin Lagoon, Odra from Párnica to the mouth should be noted:

widening and deepening of the fairway and associated turntables and passing places; Conducting dredging work in order to achieve the required parameters associated with the issuance of the water column:  mineral fine particle fraction (silt and clay), and vegetable detritus resulting from the dredging work technologies.  nutrients, inorganic and organic micro‐pollutants accumulated in the surface layer of the bottom sediment. with a consequent decrease in the transparency of water, and a possible increase in the concentration of the above‐mentioned water. substances and micropollutants. Some of these micro‐substances is considered to be particularly harmful to the aquatic environment ‐ are taken into account in the assessment of the state / potential ecological JCWP part ‐ priority substances, which are for assessing status. During dredging works following the destruction of habitats and aquatic organisms in the bottom zone, as well as on certain sections of offshore.

construction of wharfs and revetments or bottom; Construction of embankments and revetments and bottom connected with the violation of the periodic structure of the bottom and banks and their caps and excitation of bottom sediments. It relates primarily to aquatic organisms, including groups of organisms that are the objects of research the biological quality elements for the assessment of state / ecological potential. It causes a periodic silting and water column habitat disturbance and destruction of these organisms at the time the investment species living in the coastal zone and the bottom.

storage / deposition of dredging spoil; Construction of the island is a local change of shape and structure of the seabed and its coverage. It relates primarily to aquatic organisms, including groups of organisms that are the objects of research the biological quality elements for the assessment of state / ecological potential. It causes a destruction of the habitat of these organisms, periodic silting and destruction of the water column during the investment species living in the area of the bottom. Backfilling of the dredged material

deepening existing local trims Channel Mielińskim Piast and involve a periodic decrease in the number of macrozoobenthos in these places.

Project implementation and related projects will result in the emergence of the fairway ships of larger size, and in the long term, more ships than at present. This factor must therefore also be taken into account in the analyzes of the impact of the Program on water quality indicators representing the state of ecological and chemical JCWP identified.

Analysis of the scope of the Project and related projects did not identify factors that could affect the quantitative status and the chemical status of groundwater bodies.

4.2.2. Determining the list of indicators of water quality being potentially influenced by factors identified impacts of the Project.

Listed in Sec. 3.2.1 Project impact factors related projects may have an impact on the following indicators of the quality of surface water:

in terms of biological elements:  macroalgae and angiosperms (macrophytes)  benthic macroinvertebrates,  fish fauna.

Remaining indicator of water quality in this area, ie. The phytoplankton was not subject to further assessment.

While for heavily modified river water it formulated the following requirements for the class limit and ecological potential:  the size and dynamics of movement and the resulting connection of underground water corresponding only to interactions that determined the recognition JCWP for heavily modified,  continuity JCWP corresponding only to those interactions, which decided to declare it heavily modified, after taking all protective measures, to ensure "the best approximation to ecological continuum, in particular with respect to migration of fauna and appropriate spawning and breeding grounds"  forms a trough, the depth and width variation, the flow rate conditions and the conditions of the substrate and the structure corresponding only to the coastal zones of the interactions that have determined the recognition JCWP for heavily modified. Limits for other classes has not been established.

With this in mind, it was decided that later in this report will be carried out analysis and impact assessment identified factors impact of the project in relation to all the indicators mentioned in the regulation.

in terms of physicochemical elements:  transparency,  nutrients,  substances that are particularly harmful to the aquatic environment.

in relation to the chemical status:  priority substances and other pollutants listed in Annex 9 to the Regulation of the Minister of the Environment of 9 November 2011. on the classification of surface water bodies and environmental quality standards for priority substances.

Macroalgae and angiosperms (macrophytes) Thallophyta macroalgae and angiosperms Angiospermae ‐ called macrophytes ‐ are benthic flora waters both inland and coastal and transitional. Macrophytes development depends on the physical and chemical conditions in the water (temperature, salinity, transparency, concentration of nutrients) and bottom sediments (soil type, pH, redox conditions, nutrient content).

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

Macrophytes respond to the following types of pressures: changing the nutrient supply loads and concentration suspensions, and changing the structure of the edge of the bottom and the physicochemical conditions of bottom sediments.

JCWP Estuary Świna. Under JCWP Świna Estuary is planned to deepen the existing fairway to a depth of 14.5 meters. Currently, the depth of the technical section of the track is 14.3 m. The dredging work ‐ carried out in the framework of the statutory tasks of the Maritime Office in Szczecin ‐ will not go beyond the scope of the track and thus they do not endanger the optionally present in the vicinity of macrophytes.

JCWP Szczecin Lagoon. Vegetation Szczecin Lagoon is concentrated in the coastal zone (littoral) and in the shallows. The project does not interfere in these areas. Dredging work will only affect the existing fairway. However, in areas where the planned location of artificial islands ‐ constructed in dredge spoil originating from the deepening seaway ‐ there was no occurrence of any plant species [26]. The factors that prevent the development of macrophytes in these areas are most likely too large reservoir depth, limited availability of light, strong heave, poor water transparency). The resulting island will help over time to improve the ecological potential JCWP Szczecin Lagoon, among others, macrophytes in the field ‐ they will be colonized by vegetation, rushes, and in the coastal zone will start to grow vegetation and sea.

Bodied ‐ within the accompanying investments ‐ new quays fragment Świny the edge of only approx. 0.16% of the length of the coastline JCWP Szczecin Bay, and is highly urbanized areas.

This entitles you to determine that the project will have no negative impact on the ecological potential JCWP Szczecin Lagoon in the range of macrophytes, and in the longer term, may even contribute to its improvement in this regard.

Measles JCWP from Párnica to the mouth. According to the information in zawartyni [26] species diversity of macrophytes waters covered by the project is small. The plants are concentrated only in the coastal zone. In the trough, due to the presence of the fairway, macrophytes are absent. The most common species is listed common reed, forming larger or smaller patches. Relatively frequently observed species is also yellow water lily, growing in the accumulation of organic matter and sheltered ‐ where slightly indented coastline forms small bays. Other macrophytes are single, without creating their own communities. Pleustofity prevail ‐ free‐floating in the water or on the surface ‐ the ryzofitami, water plants which are rooted in the base [26].

In [26] presents the state of macrophytes in the areas of interference Project peripheral zone JCWP Measles from Párnica to the mouth and the possible effects of this interference as a loss positions. In the absence of the State Environmental Monitoring Research, responsible for the assessment of water status, it is difficult to estimate to what extent these losses can have a negative impact on the ecological potential JCWP as a whole in terms of macrophytes. Whereas, however, contained in [26] statement that the said loss or patches of vegetation positions should not reduce biodiversity area adjacent to the project sites interference in the peripheral zone and taking into account that the above. space ‐ understood to be strengthened or built over the edges of quays fragments ‐ are only approx.

Benthic macroinvertebrates. Benthic macroinvertebrates (Macrozoobenthos) are the fraction of organisms inhabiting the surface of bottom sediments (epifauna) or inside (infauna), which remains after washing on a sieve with a mesh opening of 1.0 mm.

Most species macrozoobenthos prefer doped organic material which is a food base necessary for their development. Too high a content of organic matter in the sludge ‐ caused by excessive eutrophication ‐ is, however, degradation of these organisms.

In the conditions of the waters undisturbed współdominuje usually several or even a dozen species of macrozoobenthos. As the water pollution, the number of dominant species decreases, the proportion of the susceptible species ‐ a narrow tolerance range of organic ‐ is reduced and the tolerance of species increases. In extreme cases, the only species are the most resistant ‐ opportunistic [30].

Macrozoobenthos an important food base for fish, in particular from the group bentofagów. It may also be complementary to food base for diving birds, such as ducks or necked as well as other species such as gulls and terns.

JCWP Estuary Świna. Included in [39] Mouth description macrozoobenthos JCWP Świny in the project area has been prepared include on the basis of the results of studies of bottom sediments of the three selected reference points (SW2, SW3, SW4) Long‐Term Program for Maintenance of marine waterways in the area of the mouth of the Oder River in the years 2014 ÷ 2026 (hereinafter referred to as a program offshore maintenance of roads). The location of these points is shown in Fig. 13, and set points for the mean density of macrozoobenthos taxa identified and its average biomass is summarized respectively in tab.16a and 16b. Analysis of these tables shows that most often the highest density

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

Project achieved in the area of worms, mainly due to the occurrence of Pygospio elegans and Marenzelleria neglecta. And the highest biomass formed shellfish, in particular Mya arenaria.

This is also confirmed research done in 2012. By the Regional Inspectorate for Environmental Protection in Szczecin on two positions: SW IV (figure 13). Test results macrozoobenthos in samples of sediment collected in these positions, presented in tab.15 and 16. Analysis of these tables show that the state of the macrozoobenthos JCWP can be considered weak.

Under JCWP Świna Estuary is planned to deepen the existing fairway to a depth of 14.5 meters. Currently, the depth of the technical section of the track is 14.3 m. Dredging works ‐ which will be made in the framework of the statutory tasks of the Maritime Office in Szczecin ‐ due to their scope should be regarded as podczyszczeniowe maintenance work. They will not have a material impact on the ecological potential JCWP Mouth Świna in terms of macrozoobenthos.

As part of the natural inventory carried out for the report on the impact of the project on the environment [26] were made research macrozoobenthos in places where it is planned execution of the islands of ore coming from dredging the fairway ‐ position: W22, W27 and W28 (Fig. 13). Attempts bottom sediments collected by the catcher Van Veen in the period from 18 to 21 October 2014.

In the tests, the presence of species characteristic of the muddy bottom of the Szczecin Lagoon and the dominant skąposzczetów and larvae Chironomidae (Tab. 18 to 20). Only the station W27 experienced individuals Dreissena polymorpha, with mean density osobn./m2 90 and the biomass 10.8 g / m2 (Tab. 19a and Tab. 19b.). In the areas intended islands was not detected sensitive or valuable species of invertebrates. The sampling areas bottom is muddy, prevailing poor oxygen conditions, which can be inferred from the nature of the solid and the odor originating from the decomposition of organic material [26].

Ww. perceptions about poor taxonomically bottom makrofaunybezkręgowej Szczecin Lagoon is also confirmed by studies done in 2011 and 2012 by the Regional Inspectorate for Environmental Protection in Szczecin. Test results macrozoobenthos in samples of sediment collected at different positions WIOŚ were summarized in Table. 21 ÷ 27. Analysis of these results indicates that only the position E located in the vicinity of the island Chelminek macrozoobenthos state can be considered moderate, while in all other positions he is weak at best.

Deepening or widening and deepening of the fairway cause physical removal of the layers of bottom sediments, with vs those found in the organisms, and then transferring it to a designated dumping site or other parts of the track in order to compensate for existing trims. This means that in places of work of dredging and spoil deposition macrozoobenthos periodically cease to exist. This impact will affect approx. 4.77 km2 JCWP Szczecin Bay surface [27, 39] which is 1.2% of its total area.

After completion of dredging work space deepened and widened fairway will gradually re‐ populated makrobezkręgowcami benthic by migration from areas adjacent (e.g. see .: Corophium, Gammarus, Oligochaeta, Gastropoda) or by deposition on the bottom of planktonic larvae (this Bivalvia and polychaetes) . Reappearance at these sites common in sediments Szczecin Bay larvae Chironomidae apparent from the course of the reproductive cycle of these organisms ‐ submitted by it on the water surface eggs drift, and then sink and sink to the bottom, where the hatch of larvae.

It should be emphasized that the process of the playback unit macrozoobenthos important is also the length of the life cycles different taxa. Organisms living several years (eg. The clams) are not able to reproduce rapidly in population structure that existed previously. This may result in a rapid increase in the number of these organisms in the area of in‐depth, but their slow playback biomass. In contrast, areas that are often exacerbated never be able to recreate the full structure of macrozoobenthos, characteristic for the area. In this case, the bottom is occupied by the benthos depleted structure organisms with short life cycle and high dispersion. Macrozoobenthos biomass in these areas will always be low. This is confirmed by the study,

Odra in the years 2014‐2026 [10]. A good example in this regard is the reference point SW1, located in the estuary stretch Świna (Fig. 13), in the area where he regularly works are carried out dredging associated with the maintenance of the fairway ‐ these works were performed in 2012, 2013 and 2014. This station is characterized by the extremely low density makrozobentosu (315 os./m2) and its very low biomass (1.5 g / m2).

Dredging works related to the widening and deepening of existing tracks and should not cause a decrease in the number of species of macrozoobenthos species and changes in the share sensitive and resistant to stress caused by eutrophication. This is confirmed by, among others, the results of monitoring pre‐investment, investment and pro‐investment led to the task of construction of breakwater for the external port in Swinoujscie. [73] Positions covered by this monitoring, a year after the impact of the works that could have a significant impact on the structure of benthic disturbing, is still visible. For example, in one of these positions (position ZP 2, located near the above. Positions SW2 and SW3) were only approx. 50% of the biomass and abundance of mussels listed before the investment. In relation to the total biomass of macrozoobenthos qualitative similarity of dominant and subdominantów was 75%, and in terms of the size of only 28%. However, the rate of biodiversity Shannon‐Wiener determined for this position for a period of pre‐ and poinwestycjnego was almost identical to [39].

Storage of dredging spoil fairway as the corresponding island or islands filling means at certain places Szczecin Bay bottom sediments with living therein makrobezkręgowcami benthic, leading to their destruction. This interaction will apply to approx. 3.8 km2, which is less than 1.0% of the JCWP Szczecin Lagoon.

Establishment of the islands will mean the emergence of new littoral zones, which will be occupied by other species than was found in those places previously in the bottom mud. It is anticipated that it can produce a rush, submerged vegetation occur, as it did in the case of island Chelminek. Through the increase of various kinds of vegetation and habitat generate a mosaic to be harboring taxa macrozoobenthos more than a muddy bottom, therefore, increase the biodiversity of the assembly. It is difficult to predict whether we will have to deal with the increase in the density or biomass [39]. It is worth mentioning that the above‐cited studies in Szczecin WIOŚ clearly show

One of the effects of the creation of the islands will be the formation of new shoals Dreissena polymorpha. Mussel has a beneficial impact on the water as by filtration contributes to the reduction of blooms and turbidity of water, and by depositing agglutinates (filtered algae) and calcium carbonate gives good habitat for other invertebrates [39]. Dreissena polymorpha be colonized coastal islands with the greatest intensity from 0 to a depth of about 5 meters.

Dredging work on the fairway and the discharge of excavated material will cause turbidity, most felt in the immediate vicinity of works. The range of the spread of this will depend on the turbidity existing at the time of the currents and wind power. Excess slurry may cause clogging of the filtration apparatus odfiltrowujących animal feed water. However, this problem affects mainly planktonic organisms that can not stop filtering, because it is associated with respiratory movements of legs, for example. Cladocerans. Most benthic filtratorów reacts to sudden changes in the environment closure shell, burying the houses like. They can thus safely survive transient turbidity or other deterioration [26]. It should also be emphasized, that in the Lagoon Szczecin, because of the shallowness and the undulation at the bottom of the water is usually heavily loaded suspension. Present in the basin organisms are therefore adapted to such conditions.

As a result of violations of bottom sediments may appear local changes in water chemistry, relating primarily to decrease the amount of oxygen, reduce the redox potential, or the release of toxic substances deposited in the sediment. These factors may lead to the elimination of some, particularly sensitive taxa of macrozoobenthos. However ‐ as shown by the test results presented above ‐ in the areas where work will be conducted dredging and discharge dredged materials dominate taxa more resistant to these factors (Tubificidae and Chironomidae larvae). They should not, therefore, suffer greatly in this respect.

Destruction of macrozoobenthos can also take place in the coastal zone in places of work or the bottom edges umocnieniowych and construction or reconstruction of quays. For JCWP Szczecin Bay such work will be performed on the bank a total length of approx. 2 km, and at the bottom of a total area of approx. 0.08 km2, which constitutes a small proportion of the peripheral surface of the or JCWP (0.6% and 0.02%).

Identified factors of the Project and related projects ‐ work dredging associated with the widening and deepening of the fairway, the deposition of excavated during these works excavated works umocnieniowe and expansion or construction of embankments ‐ can thus interfere with the existing structure of macrozoobenthos and slow down ‐ or even prevent ‐ its reconstruction to good potential. In order to assess whether and to what extent their impact is significant indicator of the impact are used WskWp used in [31] for the initial designation heavily modified transitional water (see rozdz.4.1.3.2). It was assumed that the growth depicted above. impact indicator JCWP morphological changes caused by the investment will result in the same ‐ calculated as% ‐ reduction in the multimeric index B,

Bearing in mind the judgment of the Court of Justice of the European Union on 1 July 2015 in Case C‐461/13 [61], it was assumed that:

in a situation where the reduction in value of a multimeric B index results in a change of classification status / potential macrozoobenthos, even if it does not translate into a change in the assessment of the overall

103

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

JCWP state, is considered analyzed the investment has a significant negative impact on the state of macrozoobenthos and can cause deterioration JCWP;

in a situation when the state / potential macrozoobenthos monitoring positions located within the project impact is in the fifth grade classroom, any reduction of the multimeric B index is considered a significant impact on the state of macrozoobenthos investment is likely to cause deterioration of the JCWP.

It should be emphasized that according to Polish law for JCWP Szczecin Lagoon ‐ despite believing it to be heavily modified ‐ for macrozoobenthos apply the same limits as for the quality classes transitional waters not treated as significant morphological pressures.

In the case under consideration Project and accompanying investments it is estimated that the impact of the change indicator for JCWP Szczecin Lagoon will amount to 2.63% (see chap. 4.2.3.2). When determining the initial state ‐ corresponding to the measured in the years 2011 and 2012 the index values multimeric B ‐ were taken WskWp = 19.28, ie. The pre‐implementation phase II upgrade the fairway. According to previous assumptions, this means reduction of the multimeric index B for the respective positions of the monitoring also 2.63% (See Tab. 28).

With tab. 28 shows that the above. lowering the multimeric B index positions located within the monitoring of the Project and related projects will not result in the reclassification of water quality in terms of macrozoobenthos to the lower class.

However, due to the fact that three of these positions macrozoobenthos is in the fifth grade classroom, it should be considered, the project has a significant negative impact on the ecological potential JCWP Szczecin Lagoon in the range of benthic macroinvertebrates.

Measles JCWP from Párnica to the mouth.

As part of the natural inventory carried out for the report on the impact of the project on the environment [26] were made studies of macrozoobenthos in the littoral zone of islands along the fairway between Szczecin‐Police (Mieleński Ostrow Mieleński, Ostrow Grabowski, Mieleńska Meadow, United Kepa, Radolin, Debina , Crane, Fish Ostrow, Kopin, Raduń, Long Ostrow, Karwa Great). 2 inspections were carried out: in the spring (16.05.2015 r.) And in summer (22 and 27.07. 2015.). According to [26], found as a result of the control taxa macrozoobenthos taxa were commonplace typical test section of a river. They occurred mosaic, depending on the ground of the site.

Inventory in the spring showed virtually no representatives macrozoobenthos [26]. The occurrence of individual animals merely shellfish succession amphipods (Amphipoda) belonging to the suborder kiełżowatych (gammaridea) representative bugs heteroptera (Hetroptera) species Nepa cinerea (NEPA cinerea) mszywioła cristatella mucedo. Mszywioł this occurred at the entrance to the Eagle Isthmus, in a sheltered by lodges and most likely came from the lake Dabie. The area covered by the drift zone inventory identified the presence of mussel (Bivalvia) from the family skójkowatych (Unionidae) of the species duck mussel (Anodonta anatina) painter's mussel (Unio pictorum) swollen river mussel (Unio tumidus). There was no presence of rare species or protected.

Inventory in the summer period demonstrated an increase in the number of macrozoobenthos and more taxa identified [26]. The smallest number of taxa characterized by medium sand, gravel and small stones ‐ were found in such places only single specimens and sharpened skójki painting, duck mussel, zebra mussel (Dreissena polymorpha) and single Gammaridae. In the case of hides in the form of cavities in the rim or the roots were found cancer zebrafish (Orconectes limosus). The presence of the plant to increase the number of affected Gammaridae, appeared crustaceans belonging to the genus Mysidacea. Most rich fauna characterized by the shores of islands Ostrow Mieleński and Property, where the vegetation was the richest littoral dominance with yellow water lily, osoki aloesowatej, pondweed crested. In the littoral of these islands found numerous: gammaridea, Mysidacea, Orconectes limosus., Anatina Anodonta, Unio pictorum, Unio tumidus, Dreissena polymorpha, viviparus viviparus, planorbarius corneus, Chironomidae larvae, Gerris sp. And a number of littoral cladocerans. There was no presence of rare species or protected. In July also found the presence of common species imagines dragonfly on the edges of the Oder: Ischnura elegans and Orthetrum cancellatum.

When performing the inventory was seen very strong impact on the coastal zone of the islands of waves generated by a passing unit. Even the movement of waves coming close small units of about 2 meters deep into the beach and caused leaching of land. In turn, on the coast covered with common reed (Phragmites australis), the plants are strongly bent and performed very strong current of water, introducing strong disturbance in the environment. In May, in the littoral islands, there was no other outside reed submerged vegetation. However, in July in some places it appeared submerged vegetation represented mainly by stuckenia pectinata. With the advent of this type of vegetation has increased the size and number of taxa of macrozoobenthos ascertained.

There are no studies on macrozoobenthos Odra estuary. The nearest examined in this respect sections of the rivers Oder Eastern and Western Odra, which is located between Park Lower Oder Valley Landscape. Despite the proximity and abundance of macrozoobenthos in these sections is significantly different from that found for the section of the Oder River estuary. [26] This is due to the different nature of habitats occurring in these areas. Underlining requires that, after the Oder East and West are movable unit of multiple times the tonnage of less than immersion and seaway Swinoujscie‐Szczecin. Ripple caused by these units does not result in such large havoc in the coastal zone, as is the case for individuals with high tonnage moving the aforementioned. track in the Odra estuary. Nevertheless, even in the case of the Oder River in Eastern and Western bentofauna littoral it is poorer than that found at the bottom of the river bed [60].

Ww. This observation confirms the macrozoobenthos study done in 2012. by the Regional Inspectorate for Environmental Protection in Szczecin Senior Western Odra ‐ Base SUM (Stettin) (fig. 13). The results of these tests are presented in Table. 29.

In Poland, for the evaluation of water quality based on the status indicator macrozoobenthos used wielometryczny MMI_PL. It is a weighted average of the normalized values of the six metriksów used in biomonitoring hydrobiologicznym, ie .:

Averaged Water Quality Indicator (ASPT) ‐ quotient of BMWP‐E (ie, the sum of points assigned to the families of benthic invertebrates) and the number of bulleted families;

presence taxa sensitive pollution with organic compounds and biogenami (ASPT) and the hydro‐morphological changes (number of families EPT); uniformity of the occurrence of important functional groups (1‐GOLD).

WIOŚ test results indicate that the state of the macrozoobenthos JCWP Odra from Párnica to the mouth should be assessed as weak.

The enlargement (from 90 to 100 m) and deepening the existing fairway may delay or slow down the ‐ and even prevent ‐ the reconstruction of macrozoobenthos JCWP Odra from Párnica to the mouth of the potential good. Analyzes [26] it shows that the presence of this track ‐ in JCWP is a track section from km 44.000 to km 62,100 ‐ and its operation may be a major factor in determining the current weak ecological potential (class IV water quality) in terms of macrozoobenthos. It should be emphasized that according to Polish law for JCWP Odra from Párnica to the mouth ‐ despite believing it to be heavily modified ‐ for macrozoobenthos apply the same limit as second class quality for the river is not subjected to such a significant morphological pressures.

The factors that disrupt the existing structure makrozobentosu are also working umocnieniowe bottom and banks and building embankments. In the case of Measles JCWP from Párnica to the mouth, umocnieniowe work will be carried out only within the framework of the project ‐ the strengthening of embankments along the bottom of HUK, Nautical and BON on a total length of 0.26 km and an area of only 0.01 km2. However, in the framework of the investment associated with one of the existing wharves in the JCWP (Cereal on the peninsula Eve) has been extended by 35 meters. Other, mentioned in the table. 1, strengthen or bottom edges and the construction of wharves ‐ planned on the fairway from km 62.100 to km 67.424, Grabowski Canal and Port of Szczecin will be implemented outside the JCWP Odra from Párnica to the mouth. The planned investment in the Port Police concerns JCWP RSS Police. The above leads to the conclusion,

In order to estimate the extent of modernization influence on the state of the fairway macrozoobenthos can be important measure was used similar to that used in [31] for the initial designation heavily modified coastal waters transitional impact indicator WskWp (see chap. 4.1.3.1 and 4.1.3.2) .

It has been assumed that the effect of morphological changes caused JCWP upgrade path for Macrozoobenthos can be quantified using the impact indicator WskWT described by the following formula:

 n LT WskWT (WskZn d)  m  (1) and LJCW

108

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

where: n ‐ the number of kinds of morphological changes caused by the modernization of the fairway within JCWP evaluated. WskZn ‐ relevance indicator morphological changes d ‐ morphological changes expressed by the relative increase in the track surface AND  AND m ) Or relative increase in the length L  L (as m ) LT sections (as AT at which these changes occur,

It was assumed that depicted above. indicator morphological changes due to the modernization JCWP fairway will result in the same ‐ calculated as% ‐ reduction in the rate wielometrycznego MMI_PL characterized condition / ecological potential in the range of JCWP macrozoobenthos. In the case where the reduction at the same time it means a reclassification to a lower class, it is considered that the planned modernization of the fairway has a significant impact on the current state of the macrozoobenthos. It was assumed that:

in a situation where the reduction in value of the index wielometrycznego MMI_PL results in a change of classification status / potential macrozoobenthos, even if it does not translate into a change in the assessment of the overall state of JCWP, is considered analyzed the investment has a significant negative impact on the state of macrozoobenthos and can cause deterioration JCWP;

in a situation when the state / potential for macrozoobenthos monitoring stations located within the project impact is in the fifth grade classroom, any reduction of the rate wielometrycznego MMI_PL recognized the important impact of the investment on the condition of macrozoobenthos likely to cause deterioration of the JCWP.

Inventoried in this volume morphological changes in the JCWP Odra from Párnica to the mouth are summarized in Table. 30. This table also corresponding to each change signification indices and the calculated impact indicators ‐ partial and total.

According to this prior assumption will reduce the mean values of the position wielometrycznego MMI_PL water quality monitoring Measles ‐ Base SUM (Szczecin) also about 22.62%, ie. From 0.356 (IV quality class) to 0.275. This reduction will not result in the reclassification of water quality in terms of macrozoobenthos to the lower class. Thus it can be concluded that the project had no significant impact on the ecological potential JCWP Odra from Párnica to the mouth.

Fish fauna.

JCWP Estuary Świna. As part of the natural inventory carried out for the report on the impact of the project on the environment [26] in the spring and autumn of 2014. In the area JCWP Mouth Świna were made half of research along the transepts with a length of 1,500 meters set out on three positions: SW2, SW3, SW4 ( figure 14). Half of these were carried out using towed gear (bottom trawl).

The results of the study summarized in Table fish fauna. 31. The halves of the spring season recorded 14 species of fish, the autumn season ‐ 13, in both the total of 17 (Tab. 32). It has been found that the farther from the edge of the diversity of fish species is higher. In the spring it grew from 1.2 bit on the subject, przyujściowym Świna transect, the value of almost 2 bits per individual, in the northernmost transect SW4. In the autumn season rate of biodiversity in the Shannon‐Wiener transect SW4 far exceeded the value of 2.

Given that the modernization work on the fairway will be conducted only on the stretch from shore to approx. 800 m toward the open waters of the Gulf, and their scope is comparable will work utrzymaniowymi, it must be considered that the project will have no significant impact on the ecological potential JCWP Świna estuary fish fauna in the area.

JCWP Szczecin Lagoon. As part of the natural inventory carried out for the report on the impact of the project on the environment [26] in the spring and autumn 2014. JCWP in the area of Szczecin Lagoon catches were made on five research positions (Fig. 14), ie .:

ST2, BT3, ME‐W ‐ the positions of these, located in the southern Great part of the Lagoon, catches equipment position control performed with the use of the network sector set out along the transects a length of 1500 m;

TW2, M1 ‐ these positions, located in the northern part of the Lagoon of Holy, yields were carried out using the towed equipment (trawl) transepts along a length of 1500 m.

Results of testing carried fish fauna are presented in Table. 33a, and 33b. On the above. positions have been reported a total of 16 fish (Table 34). It was found that the species of fish fauna becomes poorer as the distance from the shoreline Lagoon, while increasing the concentration of the dominant species. The level of biodiversity of fish fauna near the port Stepnica (position ST2) was almost twice as high as the transects in the central part of the basin (position 3 and BT‐ME‐ W). The presented results (table. 33b) attention is almost 6‐fold higher rate of biodiversity Shannon‐Wiener transect the position TW2 (located in the vicinity of the New Warpno) relative to transect the position M1 (located adjacent the peninsula trench in the eastern part of the Lagoon .) despite the conclusion of the same number of species in trałach performed on these transects. This difference explains a more equal share of species in the structure of the transept trapping TW2. Although the predominant part was here perch next to this species were found including three subdominacyjne presence of other species, ie. Roach, bream and ballerus ballerus [39].

Dominant in terms of numbers, when fishing with nets were percidae sector, in particular jazgacz whose density depending on the position ranged from 58.5 to 87.8%. The test results also showed that the share of older individuals of this species grows in the direction of the central part of the Lagoon.

Dominant in terms of numbers when fishing with trawl were carp, whereby the position of the M1 animals of the family were up 93.3%, and the position of TW2 only 51.4%. The position TW2 46.4% of catch numbers were percidae, mainly perch, whose density was 45.5%.

As part of the natural inventory investment made for Modernization of the fairway Świnoujście ‐ Szczecin (Channel Piastowski and Mieliński) ‐ stage II, east side and west [11] 115

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

in water Channel Piastowskie and Channel Mielinski were found nine species (sturgeon, paprosz, alosa, shrew blow Bitterling, loach, goat, loach), and two species of kręgoustych (lamprey and lamprey), mentioned in Annex II of the habitats .

Water Channel Channel Mielinski Piastowskie and recognizes [11] as an important passage used for both the migration cyclic, and the yearly seasonal migrations. Artificial shaped trough and reinforced edges of said channels, the use thereof for shipping and present there a significant change (variation) at the time of the flow characteristics of water and its physicochemical characteristics (direction and velocity of flow, flow rate, level of the water, sediment transport, salinity et al.) make in this area is the lack of well‐educated and occupying respective surfaces conducive to sustainable habitats, breeding and stayed on.

In light of the above, the results of research inventory ichtyofauna justified it seems to assume that the main corridor migration for migratory fish from the sea ‐ through the straits Swina, strange and foam ‐ for the Szczecin and further up the fugitive him the rivers and in the opposite direction is the fairway and area attached thereto. Breeding places, however, are the coastal areas of the Lagoon.

Fairway established a path of water in the environment for more than 100 years. The scope of modernization will not change the critical environmental conditions on the use of the basin as a migration route for fish. This work will not pose a threat to migratory organisms ‐ if they are carried out outside the period of migration of fish from the sea to the lagoon and in the opposite direction. Referring to raised in [39] issues not fully recognized the impact of noise caused by the movement of vessels on the fairway, it is worth noting that the modernization of the fairway is to make it accessible to larger vessels which in practice does not necessarily mean increasing the level of noise at the same frequency movement. There is therefore no evidence to believe that the modernization and further exploitation of these channels could adversely affect fish migrations.

Under JCWP Szczecin Lagoon Project work will not be done umocnieniowe existing banks. However, in the framework of the investment associated with building and strengthening the edge of the bottom it is planned only in the area of port Swinoujscie, on the right bank Świna waist and bottom adjacent to it. The project and accompanying investments, therefore, do not pose a threat to the breeding sites of fish in this JCWP.

From the analysis of the tests carried out it shows that due to the conditions of life of fish fauna in Szczecin Lagoon dumping site dredging fairway should be located at the greatest possible distance from the existing shoreline Szczecin Lagoon. Indicated in [39] places the location of these landfills ‐ in the form of one or three islands ‐ meet this requirement. It should also be stressed that the planned dumping site

116

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

will be located in areas of the muddy bottom of the low diversity of species present therein, characterized by high resistance to environmental stress [39].

Deposition of excavated material may cause damage to part of the population of fish fauna inhabit the island region formed ‐ this is particularly small and slow flying species. Created during klapowania excavated barriers suspension or chemical can modify the route of movement of fish. The decrease of transparency of water during the construction of the island may decrease the production of biological and disrupt the availability of food for the fish living in the neighborhood. Ww. Negative impacts will be local in nature, however, and the short‐ term.

By contrast, will result from the deposition of spoil islands should be considered a positive impact in relation dwelling fish fauna in the area. Increasing the length of the edge area and in particular littoral available to the fish fauna, the formation of microhabitat for fish of different age groups, the formation of islands will increase the heterogeneity of the habitat available to the fish fauna ‐ establishment of the seat different from where the uniform bottom muddy, dominant Szczecin Lagoon as also places the planned islands.

Poor food base, which is formed zoocenozy bottom area of the planned spoil not create good living conditions and environment for the fish fauna. Preparation in the immediate vicinity of new islands, a different team as benthos, contrary to the current, which can attract more than ever occurring species of fish there, increasing local diversity.

Caused the creation of the islands change fields bottom currents will concern small in relation to the entire Lagoon, areas ‐ the area of the islands will constitute less than 1% of the area of the Great Lagoon. So it should not significantly change the migration routes of fish. At the same time the change of the currents in the area of the islands, resulting in a reduction in the deposition of organic matter may lead to the emergence of the species in this area with higher environmental requirements or colonization while shallow areas formed by the water plants to generate formation of microhabitat, or finally spawning.

With this in mind, it should be considered that the project will have no significant impact on the ecological potential JCWP Szczecin Lagoon fish fauna in the area.

Measles JCWP from Párnica to the mouth.

As part of the natural inventory carried out for the report on the impact of the project on the environment [26] have been made research catches the fish fauna in the coastal zone between the Odra river and the Police, Szczecin, Channel Grabowski and Piercing Mieleński. 12 has been established inventory segments, which were determined from 3 to 5 points trapping spaced apart by 100 ÷ 300 m (total of 47 points). research

They concentrated in regions that were expected to disrupting the existing shoreline and changes in the structure and configuration of the edge. Efforts to investigate the most diverse types of habitat. When selecting the points taken into account, in particular: the direct location in relation to areas in the vicinity of the investment bank of a different character, a kind of bottom, the nature of the vegetation and the associated probability of presence of fish in various stages of age. Catches were carried out at the turn of May and June 2015. Using an approved kit elektropołowów.

Results of testing carried fish fauna are presented in Table. 35a ÷ tab. 35c. In sections of inventory it has been reported a total of 12 fish (Table. 36), including two protected (caprine and asp).

The area covered by tests stated locations of special interest for fish that can be used as spawning [26]. The entire stretch of the Oder River estuary in the area of Swinoujscie‐Szczecin is in fact long been subject to strong human pressure (the waterfront and the heavy traffic and vessels). In contrast, the edge sections unchanged or slightly changed by human are covered by trees ‐ some of which are due to wash the infected by the water has been roll‐over ‐ or wide belts compact and rushes. Relatively few places shallowed occupied by submerged vegetation, which usually is a substrate for laying eggs and, just as importantly ‐ sheltered from direct traffic surge caused

coastal zone is not conducive to spawning. Favors while bytowaniu fish. This applies to both actively floating fry and adult forms. This is confirmed by the results of the research. The most varied species were episodes inventory 1, 2 and 5 (respectively 10, 7 and 6 species) contained in reservoirs with small depths, the edges rich fallen or growing on the edge of the water trees, vegetation submerged and floating leaves, and a low density rushes. In the course of the Project should therefore take into account the changes in the existing structure of fish fauna due to displacement of parts of individuals in places not threatened. After its completion, however, you can expect a fairly rapid return to the status quo.

With this in mind, it should be considered that the project will have no significant impact on the ecological potential JCWP Odra from Párnica to the mouth of the fish fauna in the area.

4.2.3.2. Hydromorphological elements.

JCWP Estuary Świna. Under JCWP Estuary Świna is only a 800‐meter stretch of the Swinoujscie‐Szczecin. As part of the so‐called. accompanying investment is intended to be deepening to 14.5 m. depth technical Currently, this section of track is 14.3 m. Dredging works ‐ which will be made in the framework of the statutory tasks of the Maritime Office in Szczecin ‐ due to their scope should be considered as maintenance work podczyszczeniowe . They will have virtually no significant effect on the ecological potential JCWP Mouth Świny in the range hydromorphological elements.

The outflow of water from the lagoon to the Pomeranian Bay and the inflow of marine waters Lagoon depends on the difference in water levels of the reservoirs. Increasing the cross‐sectional area at the mouth of the fairway Świny approx. 1 ~ 1.3% did not cause detectable changes in hydrological regime or current distribution. Will not affect the meteorological conditions of the area and will not change the retention time of water.

Increasing the depth of the existing fairway only approx. 1.4% will have practically no influence on the estuary JCWP Świny both in plan, as in terms of the depth (bathymetry). The bottom of the fairway, due to the presence of water currents with variable directions and speeds, naturally subject to local variations. Deepening the track of 20 cm will not, therefore, a significant change in its structure and quantity of the substrate (the particle size, the content of organic compounds). It does not involve a change in the organic compounds in bottom sediments.

The Ordinance of the Minister of Environment of 22 October 2014. On the classification of surface water bodies and environmental quality standards for priority substances when evaluating the morphological transitional waters was specified index structure of the band tides ‐ described by covering the plant and the composition of the vegetation belt shore subject to tides . Tides in the Bay Area are just a few centimeters, which makes her area would be hard to extract even subject to the tides belt shore. Deepening the fairway to disturb the natural rhythm and size tide the present JCWP.

As a result of the planned dredging work there will be no change in the index impact WskWp JCWP considered (see chap. 4.1.3.1).

JCWP Szczecin Lagoon. The planned deepening and widening of Swinoujscie‐Szczecin may cause changes in the hydrological regime JCWP Szczecin Lagoon, ie. A change in the section of water outflow from the Szczecin Lagoon to the Pomeranian Bay for three straits (foam, pigs and Dziwna) and changes in the inflow of salty sea waters of the Bay .

To estimate the effect of upgrading Swinoujscie ‐ Szczecin river water outflow section between pigs and Dziwna The foam was used in the relation given by Mielczarskiego in [23]:

The calculations take into account the condition that the difference in water levels between the nodes of the system Świna arms, determined along the right shoulder must be equal, respectively.

For the conditions of the pre‐planned modernization fairway assumed values for damming the flow Świna strange and foam defined in [23] to 1970. These values are shown in Table. 37. In this table, with respect to Świna, summarizes the values of the parameters used to determine the coefficients stacking flows on separate sections of both her arms. The values of these parameters were estimated by the author of this volume based on literature data.

In the calculation of the conditions after the planned modernization (Tab. 38) assumes values for odd stacking of flow and foam as in [23] and the coefficient for damming the flow Świny determined taking parameters for each of the arms shown in Tab. 37.

Obtained as a result of the above. calculation of the estimated outflow section of river water between pigs Dziwna and foam and between individual arms Świny before and after the planned upgrading fairway are shown in Table. 39 and Tab. 40. It should be emphasized that the values given in the tables share respective connections in the outflow to be regarded as a guide. The aim of the calculations was primarily to estimate the scale of changes in these shares in case of realization of the planned modernization of the fairway. Obtaining a more accurate value of the relevant calculations would require using three‐dimensional model hydrodynamic implemented for all of the analyzed bodies, under conditions of current bathymetry and after all the changes resulting from the modernization of the fairway.

On a similar scale reshuffle the outflow of river water Świna, strange and Foam showed the results of motion simulation set made using three‐dimensional numerical model of the estuary of the Oder ESTURO, developed by the Institute of Hydraulic Engineering (IBW), the PAN in 1998 ÷ 1999 the work on specific guidelines to design target solution hydrotechnical Swinoujscie‐ Szczecin [14]. This model is an implementation package trisula (delft3D‐flow), developed by Delft Hydraulics, for the area of the Szczecin Lagoon, together with the straits ‐ Świna, strange and Foam ‐ and the Bay of Greifswald and part of Pomeranian Bay (limited from the north by a line extending from the island of Rügen in the area Sassnitz to Polish shore in the area of Mrzezyno).

ESTURO model is a hydrodynamic model includes information regarding the transport equation, which allows to determine the transfer and mixing of the reactive substance, and thereby determine movement of saline.

In this model, above. reservoirs are illustrated by a curved grid, the axis of which coincides with the path of the Swinoujscie ‐ Szczecin. In the nodes of the grid, vertical layers 8 has been established with the following distribution depth: 1 (selvedge has) ‐ 5% 2 ‐ 10% 3 ‐ 15%, 4 ‐ 20% 5 ‐ 20% 6 ‐ 15% 7 ‐ 10%, 8 (near the bottom) ‐ 5%. Depth nodes were adopted: for the area of the Pomeranian Bay and Szczecin Lagoon ‐ based on nautical charts, cross‐strait Świna on the fairway and by the Szczecin Lagoon according to the surveys made by the Maritime Office in Szczecin.

ESTURO model has three open borders, where questions are boundary conditions. And so: in the western part of the Bodden and the Pomeranian Bay asked are: the level of the water table and its salinity and temperature, while the south side: the flow of the Odra and the salinity and temperature of water flowing Oder. The initial conditions are the water level, flow rate, and temperature and salinity of the water in the nodes of the net. In the calculations it was taken as the initial conditions of the same water level and a zero flow rate. The initial temperature and salinity of the waters of the basin modeled differentiated by dividing it into seven sub‐areas. Calculations were performed with the time step equal to 1 minute.

In the framework [14], using a model ESTURO was designated section of river water outflow pigs strange and foam under a steady flow of the Oder of 1000 m3 / sec, a constant level of the sea and no wind. The calculations do not taken into account differences in the density of water to eliminate the change in the proportion of cash flows due to two‐way. The results of these calculations ‐ for bathymetry fairway 1968. Bathymetry and the fairway of 1998. ‐ summarized in the Table. 41 and Tab. 42.

Comparative analysis of the results presented above estimation section mean annual runoff Oder in Szczecin Lagoon strait connecting with the sea it indicates that a planned upgrading fairway approx. 3 ÷ 5% greater than the volume of the outflow is directed pigs. Consequently, the volume of effluent waters of the Oder straits: strange and ‐ through the Little Lagoon ‐ Foam will be reduced by about. 1 ÷ 2 ÷ 2% and 3%. But this should not significantly change the functioning of aquatic ecosystems, water bodies separated on these areas: JCWP Lagoon Kamieński JCWP and Kleines Haff. Underline requires that JCWP Kleines Haff has been recognized by Germany for the coastal waters and therefore within the meaning of the Water Framework Directive as not being substantially influenced by freshwater.

In [23] Apart from the above. damming the flow coefficients for each connection Szczecin Lagoon for specific dates expansion of shipping lanes of the basin, also determined resultant damming the flow rate for the whole system of connections and average values likely bleed water level between the Baltic Sea and the Lagoon. An estimated average bleed dates for all the characteristic expansion of the sailing routes taken flow value equal to the average annual 620 m3 / s. For older dates, the value of this ‐ mainly due to the greater forest cover of the Odra river basin and reduced water consumption by the economy ‐ should be considered underestimated. Despite this, presented in [23] The calculation results show that the scale of the former hydrological changes were much larger than today's changes.

Designated in [23], values of coefficients and damming the flow of water between the average bleed Lagoon and the Baltic summarized in Tab. 43. In the last line of the table determined in this study of these parameters determined for the state after the planned upgrading fairway to 12.5 m ..

water in the Szczecin Lagoon to the elevation almost equal to the average water level in the Pomeranian Bay. The consequence of this is:

intensive exchange of water between the Pomeranian Bay and Lagoon called spiętrzeniami storm in Pomeranian Bay, raising the average salinity of the Szczecin Lagoon - conversion of the former in a fresh water tank brackish water. Extreme rise of water level in the Szczecin Lagoon and lower the Oder, constant self-Channel deepening Mielinski and Piast.

The planned modernization of the fairway Swinoujscie‐Szczecin to a depth of 12.5 m is the continuation of this process. The question therefore arises whether the change shown above hydrological regime, due to this upgrade will not:

a major enhancement to extreme water levels in the Szczecin Lagoon and the lower Odra, resulting in an increase of flood risk in this area, significant changes in salinity waters of the Szczecin Lagoon, which is a threat to ecosystems a significant change in water velocity strait Świny, and in particular the speed of bottom.

In 1999. Under the [15], by means of the above. model ESTURO ‐ previously calibrated and verified ‐ simulated variations of modernization strait Świny (eg. partition Lateral Świna elongation Channel Piastowskie, reducing the depth of the channels and Mielinski Piastowskie, execution of the orifices in the channels) and their builds. These calculations were done for the bathymetry of the track 1998. In all embodiments, it was assumed increase of the channel width of the marine bottom 90 m to 110 m. Simulated hydrodynamic two situations: the average storm (which occurred during the period 10 to 10.20.1985 r.) And extreme storm (which occurred during the period of 31.10 ÷ 7.11.1995 r.). In order to evaluate alternatives comparisons were performed, among others, changes maximum water levels in the lagoon selected points (ie. the outlet of the channel Piastowskie to flooding in the area of thinning in the south‐east and north‐west of the Lagoon).

In view of this volume, the most interesting variant is the shortness Channel Mielinski and Piastowskie to 10.5 m, referred to as a variant of 10.5 m. This option as it allows to estimate the scale that may be changes in the level of water and its salinity in Szczecin Lagoon a change the depth of the shipping channel. Presented in [15], the simulation results indicate that the flattening of the channel bottom and Mielinski Piastowskie to a depth of 10.5 m in relation to the bathymetry 1998. Resulted in only a 2‐3 cm change in the highest levels of water under ordinary storm.

According to [13, 16], using the model ESTURO, we were also performed testing the effect of deepening a fairway strait Świny from 10.5 m to 12.5 m 14.5 m. (12.5 mi variant embodiment of 14.5 meters) levels and flow in Szczecin Lagoon and its salinity. It was found that increases the water level in Szczecin Lagoon caused by changes in the depth of the water path is small. Variant of 12.5 m in the inflow simulated storm average, the increase of water level was approx. 3 cm variant of 14.5 m ‐ another approx. 3 cm [15]. Small increases in the water level in the Vistula result from relatively short periods of influx of marine waters (1‐2 days) and a large area of the basin.

Changes in salinity in the Szczecin Lagoon, resulting from the different variants of modernization of the strait Świna assessed on the basis of the average salinity of the lagoon, which is determined from the value of the salinity in the individual layers twenty points located throughout the basin, obtained by simulating the average storm. In [15] are set to values determined in this way the average salinity flooding in terms of the average storm prior to infusion of saline (11.10.1985 r. H. 0.00) and after the storm (10.21.1985 r.). They show that the shortness of the bottom of the Piast Canal Mielinski and to a depth of 10.5 m (10.5 m variant), in relation to the 1998 bathymetry., Resulted in a slight decrease in the salinity of the waters of the Szczecin Lagoon. The average salinity of the storm was 0.881 in this embodiment dog (from 0.702 to dog the storm)

According to [13, 16] obtained in the comparison result of the simulation options: 10.5 m, 12.5 m and 14.5 m field distribution salinity and flow in surface layers and in the layers of bottom Szczecin Lagoon not indicated a significant effect of deepening the waterway in a strait Świny the range of propagation in the Lagoon seawater flowing thereto. It should be emphasized, however, that the above. Simulations were performed with a depth leaving the fairway for Lagoon Oder and at ‐10.5 m. Deepening the track at these parts to 12.5 m will mean a greater range of salt water wedge wezbraniach after heavy seas.

In [15, 16] also included resulting from simulations using a model ESTURO applications in assessing the impact of the proposed variants of modernization seaway Świny strait on the hydrodynamic conditions prevailing in the strait. It was found that with increasing depth of the waterway increasing flow Channel Piastowskim. Thus, assuming the flow in the embodiment of 10.5 m for 100%, the estimated desired track deepening to 12.5 m will increase the flow rate of approx. 20% and deepening to 14.5 can be more than ten percent. Speed at the bottom of this channel while rated as similar in all variants. At the same time stressed that the strait Świna since the construction of the Piast Canal and Mielinski is steadily deepening, whose rate in the period 1950 ÷ 1999 rated for 2 to 4 cm / year.

As part of the ongoing work on the IBW PAN specific guidelines for the design of the target solution hydrotechnical Swinoujscie‐Szczecin, using package trisula (delft3D‐flow) has been developed

129

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

Also Strait Świny model [17]. This model ‐ based on the bathymetry of 1998. ‐ served, among others, to study the hydrodynamic conditions in the Strait of Świna The side with the Old and pigs in a situation of deepening the fairway to 12.5 m. in 2009. This model has been upgraded in the field of bathymetry. Also the modified grid in order to more accurately track the position of the mapping aqueous [43, 44]. Made using this model simulations indicated that:

the current conditions of the bathymetry of the Strait of bottom Świny speed greater than a predetermined threshold speed (the speed of blurring) of 0.45 m / s are low heads of water between Świnoujście and AND gate of rail or between channels A and gate Swinoujscie larger and equal to 0.2 m (the probability of bleed water on the values of approx. 10%),

as a result of the proposed changes in the seaway Strait Świny change the slope of the water table, particularly in the channels and Piastowskie Mielińskim, which will result in changes in water velocity. Under the inflow of water into the Lagoon will be a slight increase in near-bottom water velocity in the region Cumulative Świna. Whereas, under the water outflow from the lagoon, in the case of an abrupt increase in water level in the basin, there will be a significant increase in speed in the region of bottom Piastowski Canal.

Bearing in mind that the planned modernization of the fairway will not stop the progressive deepening of the Strait Świna Project provides for filling existing channels Mielińskim trims and Piast dredged material originating from dredging work on the fairway. This will improve the safety of embankments on the track and at the same time eliminate the possibility of higher than estimated above reshuffle flows between pigs and Dziwna foam.

The retention time of the body of water is expressed as the ratio between the volume of a river, the annual supply. Volume JCWP Szczecin Bay, based on [76] can be estimated approx. 15,57 thousand. km3. Planned deepening and widening of the waterway extending through the JCWP an increase of the volume of approx. Approx. 0.08 km3 and will not cause virtually no change in the retention time of the water reservoir.

Project implementation in no way affect the meteorological conditions in the area of the Szczecin Lagoon.

Modification of the depth of the waterway at approx. 11.4 km (which consists of deepening to the ordinate 12.5 m or filling up the trims to the local elevation of 12.5 m), increase the width and depth of the fairway for approx. 27.5 km , mijanki embodiment and the construction of new or extension of existing storage facilities dredging spoils will cause changes in the configuration of the bottom surface 9 ÷ 10 km2, approx. 2.5% of the entire lagoon JCWP Szczecin.

the total length of shoreline located within the basin islands. Depending on the variant adopted storage of excavated material and design solutions adopted, it may be several kilometers (approx. 5% of the length of the current shoreline analyzed JCWP). The project will therefore affect the shape of the Szczecin Lagoon JCWP both in the plan, such as in terms of the depth (bathymetry).

Planned Project work affecting the bottom, ie. Deepening and widening of the existing fairway with the staggered arrangement and the motor unit and the construction of islands / island of refulatu or extending existing landfill refulatu not cause significant in scale JCWP Szczecin Bay, changes in the structure of a quantitative and a substrate base ( The particle size, the content of organic compounds). They do not involve a change in the organic compounds in bottom sediments. The work carried out for the gutter are in the existing deep fairway. The proposal provides no new fortifications or bottom edges in the area JCWP Szczecin Lagoon, in the framework of the planned investments associated with the strengthening of the bottom relate to only 0.02% of the JCWP.

The Szczecin Lagoon phenomenon tide does not occur [3, 36], thus indicated in the Regulation of the Minister of the Environment of 22 October 2014. On the classification of surface water bodies and environmental quality standards for priority substances for the evaluation of morphological conditions index structure of the band tides ‐ described by plant cover and composition shore vegetation belt subject to tides ‐ is not for this body of water use.

To assess the impact of the Project and related projects on ecological potential JCWP Szczecin Lagoon in terms of morphological elements may be used indicator of the impact WskWp, used for the initial determination of heavily modified water intermediates (see chap. 4.1.3.2). Demonstrate that the morphological changes resulting from the planned investment result in a significant change in the indicator WskWp impact, would give the basis for the assertion that the implementation of this investment may result in a reduction of the ecological potential in terms of morphological elements and, consequently, change the overall assessment of the JCWP. A significant change in the morphological elements may also affect the selection of the biological elements of that body and thus lead to the deterioration of her general condition. The approach used in [7], wherein the assessment of the effect of the second stage of the modernization of the fairway for environmental purposes. Made according to [7. 31] quantify the morphological changes within the body of water JCWP upon completion of the step shown that the proposed project will result in only approx. 1 the percentage change in impact indicator (WskWp = 20:27). This made it possible to recognize that it will not significantly affect the ecological potential JCWP Szczecin Lagoon in terms of morphological elements.

In the case of the Project and related projects, changes affecting the value of the indicator is the impact of changes in the scope of:

surface of the aggravated fairway (approx. 4.7 km2)

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

surface exposed to violation of sludge (approx. 1.25 km2 in connection with the embodiment of the passing place at the Lagoon) spoil storage area (with a preferred embodiment of the three islands approx. 3.8 km2) quays length (about 642.2 m).

Made according to [7, 31] quantification of the lesions in the JCWP Szczecin Lagoon the project and the accompanying investments are shown in Tab. 44. These changes result in an increase in the value of the indicator for the impact of WskWp 21.91. Stacked ‐ ie. Resulting from the modernization of the whole Swinoujscie ‐ Szczecin and the associated track operatively investment ‐ increase this ratio would be 2.63%, which in comparison with the projected increase in the depth of the track 2 m ‐ according to the author of this volume ‐ no longer allows argue that the project does not affect the ecological potential JCWP Szczecin Lagoon in the range of morphological elements. In contrast, the potential impact of the above. morphological changes in the ecological potential of the JCWP in terms of macrozoobenthos presented in Chap. 4.2.3.1.

It should be emphasized that in the current legal status of a heavily modified body of water in the field of transitional hydromorphological elements is broadcast a'priori Class II. In the case where the classification of the biological elements JCWP indicating their poor environmental potential, irrespective of the classification results hydromorphological elements (as well as physical and chemical) of the JCWP suitable class V ecological potential.

Measles JCWP from Párnica to the mouth. Project and associated developments in no way interfere with the continuity of morphological JCWP Measles from Párnica to the mouth.

Interference in the form of a trough and its variation width and depth of this section refers only to JCWP, on which the fairway. Width at the bottom of this track is now 90 m, while the width of the river is much greater. It is a water mirror 180 ÷ 200 meters and more, and downstream of the Inoujście ‐ called Domiaza ‐ even 300 to 400 m. [22]. The maximum depth JCWP Measles from Párnica to the mouth below the connection Przekop Mielenski correspond to the current depth technical or fairway is its greater. This applies in particular Domiąży, which rises to a depth of 12 m, and locally up to 14 m.

Extending fairway to 100 m and the bottom of the deepening to 12.5 m will increase the cross sectional area of the trough. For example, in track section of km 53.000 to km 54.700 increase in cross sectional area of the trough in relation to the cross‐sectional area of the fairway of current technical parameters can be estimated at approx. 7 ÷ 13%, for the section from 55,400 to km 59,100 to approx. 12 ÷ 14%, and the section from km 60.500 to km 62.900 approx. 8 ÷ 16% [27]. It can therefore be assumed that the modernization fairway within JCWP Measles from Párnica to the mouth will not greater than 16% strength increase of cross‐sectional area of its channel.

Measles JCWP from Párnica to the mouth of the river network is part of the lower Oder. United and flows (and velocity) in the individual sections of the network that network dependent feature the level of the sea and the river flows from the top (see rozdz.4.1.2.3). Determination of the value ‐ and in the case and the flow velocity on the direction of ‐ for given boundary conditions bathymetric and requires a calculation using suitable hydrodynamic models. Bathymetry change at one of the sections of the river network may result in changes in flow speed on both this and the other sections of that network. In Tab. 45, as an example, shows the values of the average velocity in one of the sections Domiąży and obtained by means of developed at the Maritime Institute of Gdansk, Branch Office in the hydrodynamic model of the lower Oder to flow characteristic Oder multi‐year 1949 ÷ 1989 and the average water level in Trzebież [29 ]. This table also contains the estimated change in the water velocity after the modernization of the fairway. Due to the fact that Domiaza is a section of the river network, which is headed up the flow of the river, it was possible

133

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

concluded that the change of flow rate in this section only result from changes in the surface of its cross‐section. The values should be treated as indicative, including no less indicate they modernization of the fairway will not cause a significant change in the average speed occurring on this section JCWP in different situations hydrodynamic determinowanych sea level and flow from the top of the Oder. No comprehensive research model on potential changes in stocks and flows in the lower Odra river network caused by the modernization of the fairway does not allow, however, to assess whether the impact of this investment in relation to other sections of the Oder JCWP from Párnica to the mouth will be as insignificant. According to the author of this volume, should therefore be considered

Project and associated developments do not affect the groundwater.

Planned Project work and investments associated with the work of violating the bottom will not cause a substantial change in the scale JCWP structure and substrate bottom JCWP Odra from Párnica to the mouth. Dredging will trough existing fairway remaining in the maintenance. Provided for strengthening the bottom will be performed on the surface approx. 0.016 km2 and a length of approx. 0.26 km as the length of courses relevant to JCWP of 24.047 and the average width of approx. 200 m is negligible share.

Measles JCWP from Párnica to the mouth was considered heavily modified body of water due to the longitudinal development (the waterfront and sea defenses arising from the function of port and shipping). Broadening and deepening running within the JCWP fairway does not involve the creation of new buildings and existing only with security. However, in the context of accompanying investment in this JCWP no plans to create new berths (except elongation of 35 m waterfront Harvesters Peninsula Eve). It should therefore be considered

4.2.3.3. physicochemical elements

Transparency During the implementation phase of projects part of the program will be a temporary decrease the transparency of water due to dredging work carried out within their borders.

When carrying out dredging work, by means of dredging buckets to the surface in contact with the surrounding water, which leads to a dilution of the top layer of the precipitate collected. Freed in this way, part of the organic detritus (muds) and the fraction of mineral clay, silt or fine sand ‐ under the influence of surface currents and subsurface wave and ‐ no sediments around dredgers, but is kept as a suspension by increasing the turbidity of the water.

According to [10], the predominant fraction of sediment covering the bottom Szczecin Lagoon fairway and its surroundings are fine sands or mules very coarse and coarse. the share of organic matter in the sediments depending on the period and position ranges from less than 1% to over 20%.

In order to estimate the expected range of influence of the spread of the ore during dredging Szczecin Lagoon calculation resultant angle φ characterizing the movement of the grains sludge during sedimentation (angle characteristic falling grains), which depends current speed v and the speed of sedimentation of grains precipitate in water ie .:

Settling velocity of grains precipitate in the water was determined using an empirical relationship Onoszki: ρ 9.45 ‐ 1 0.8 [Cm / s]

ρ 50

where ρ is the density of water, and ρs density solid.

As best characterized median diameter particle deposits in the area of fairway assumed d50 = 0.15 mm and d 50 = 0.03 mm

The range spread excavated material (turbidity) was calculated from the relationship:

where hp It is the maximum depth of a natural body of water adjacent to the current track or the depth of the fairway. The calculations were performed for the following assumptions:

– water density ρ = 1.002 g / cm3.

– solid density ρs = 1.6 g / cm3. – the depth of the body of water or waterway hp = 6 m, 10.5 m – water current velocity v = 5, 20 cm / sec (see chap. 4.1.2.2) and the results are summarized in Tab. 46a and Tab. 46b.

Moving seaway vessel may influence the slope and on its bottom by an underwater excavation waves and the return current caused by the movement unit and the water and shock caused by operation of the propeller (called. Zaśrubowy current). According to [45] of the vessel the return current flowing along the edge of the waterway may be estimated at approx. 2.0 m / s. Current zaśrubowy according to [56] of the vessel at a speed equal to 2 m / sec is estimated to be 1.5 m / s. Ww. speed is higher than the speed recognized for the diminishing of the fairway (0.45 m / s), but also comparable to that occur during periods of storm surges [45]. This means that the movement of vessels on the fairway may cause local and short‐lived decline in water transparency in the gutter of the fairway, which will not have a significant impact on the ecological potential JCWP Szczecin Lagoon in terms of this indicator.

nutrients Due to the fact that the work performed will be drawn on the existing and continually in the maintenance pogłębianym seaway, the content of the general form of nitrogen and phosphorus in the extracted ore should not be particularly high. The release of these elements and their dissolved forms of the water column in the course of the dredging works will be similar in nature as in the storm ‐ after termination of forcing agent after a relatively short time will inherently return to the pre‐existing balance between the above‐mentioned content. substances in sediments and water. According to the Guidelines on exemptions from the environmental objectives [74], it should be considered that due to fluctuations in such a way that the water quality does not require the application of Article. 4, paragraph 7 of the Water Framework Directive.

Substances particularly harmful to the aquatic environment In the course of the dredging works release of substances may be particularly harmful to the aquatic environment accumulated in the bottom sediments and to increase their concentration in the medium to the level of toxicity to aquatic organisms.

performed inside surface waters, should check if the output does not have the properties of "eco‐toxic" (H14) and does not contain the ingredients listed in Annex 4 in concentrations exceeding the concentration limits of hazardous substances.

For the purposes of this law, 'eco‐toxic' is considered waste which presents or may present immediate or delayed risks for one or more sectors of the environment. Attribution of the properties' eco‐toxic "‐ in accordance with Note 1 in Appendix 3 ‐ is made on the basis of the criteria set out in Annex VI to Council Directive 67/548 / EEC of 27 June 1967. On the approximation of laws, regulations and administrative provisions relating to the classification, packaging and labeling of dangerous substances (Journal. machines. No L 196, 08/16/1967, p. 1). However, in accordance with note 2, where appropriate, apply the limit values specified in Annexes II and III to the Directive of the European Parliament and Council Directive 1999/45 / EC of 31 May 1999. on the approximation of laws, regulations and administrative provisions of the Member States relating to the classification, packaging and labeling of dangerous preparations (Dz. Office. EC L 200, 30.07.1999, p. 1).

The Polish legislation ‐ Article. 2 paragraphs. 6 The Minister of Environment dated 13 May 2004. On the conditions in which it is recognized that the waste is not dangerous ‐ condition for recognition of that waste listed hazardous waste does not possess ecotoxic (H14), is the lack of toxic effects in conditions screening tests conducted with a standard aqueous extract from waste. A list of these tests is provided in Appendix 2 to the above. Regulation.

In the absence of the relevant Polish regulations to check whether in ore that will be mined in the course of implementation of the planned investment is the lack of border crossings concentrations of substances hazardous to the aquatic environment can be used to Regulation (EC) No 1272/2008 on classification, labeling and packaging of substances and mixtures (CLP). This regulation implements into EU law the second edition of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) by the United Nations. It entered into force on 20 January 2009. The CLP Regulation amended Regulation (EC) No. 1907/2006 (REACH) and gradually, with appropriate transitional periods.

, CLP [54] lists of hazardous substances include a hazard classes, categories / sub‐class / type within a given class of risks specific concentration limits (if different from the general concentration limits given in Annex I to the regulation) ‐ the excess of which qualifies the substance to dangerous and potential value of "M", used in the classification a mixture in which the substance is present.

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

Among the hazard classes has been awarded the class' hazardous to the aquatic environment ", which have been separated five categories: Category 1 Acute and Chronic Categories 1 ÷ 4. For the hazard class, the following basic values (expressed in percentages by weight):

for Acute Category 1 and Chronic Category 1 ‐ 0.1% for chronic category 2 to 4 ‐ 1%.

Where the above. combination of substances in relation to the specified categories of risks is given M‐factor, the basic limit value must be adjusted using the appropriate formula given in the Regulation.

In the case of using excavated to build islands, excavated material should be treated as waste. It must, however, comply with the conditions contained in the Regulation of the Minister of Environment dated 11 May 2015. In the recovery of waste outside installations and equipment [51].

In the framework [42] in the Swinoujscie ‐ Szczecin were obtained core sample with a length of 1.0 m with a depth of 1 m and a depth of 1 to 2 m below the bottom and with a length of 2.0 m with a depth of 1 to 2 m below the bottom . With the above. core samples then averaged formed assays, representative of the respective 2‐kilometer lengths fairway. These attempts were tested chemical, consisting inter alia the determination of the metal content, ie .: arsenic, chromium, zinc, cadmium, copper, nickel, lead and mercury. In each of the above‐mentioned contents of the samples. Metal was much lower ‐ in some even dozens of times ‐ than the limit permitted in the Regulation of the Minister of Environment dated 11 May 2015. in the recovery of waste outside installations and equipment [51].

Given in [42] above‐mentioned results. studies of bottom sediments taken from the track in the field of aqueous inorganic micropollutants, which are indicators of water quality from the group of particularly harmful to the aquatic environment are summarized in Tab. 47. This table shows the maximum values of the abovementioned concentrations. substances identified in the collected samples (expressed in mg / kg DM and percentages by weight) and the limits and categories of hazards to the aquatic environment established for these substances in the CLP Regulation, as well as the limits laid down in the Regulation of the Minister of Environment dated 11 May 2015. in the recovery of waste outside installations and equipment [51].

By analyzing the above‐mentioned concentrations. metals contained in the harmonized classification and labeling of dangerous substances attached to the CLP [54] in any of the test samples did not exceed sludge concentration limits resulting in that the presence of these metals in the ore it would be classified as causing a risk.

By analyzing the above‐mentioned concentrations. metal, as indicated in [51] as the release determining ore for use in the construction, development and maintenance of the construction of hydraulic structures, in any of the samples tested, there was no sediment exceeded permissible values.

Considering the above it can be concluded that the project carried out under the dredging work will not result in increased plasma concentrations of the above. substances particularly harmful

After the cessation of dredging work in a relatively short period of time will be spontaneous return to the pre‐existing balance between the content above. substances in sediments and water. According to the Guidelines on exemptions from the environmental objectives [74], it should be considered that due to the fluctuations in water quality does not require the application of Article. 4, paragraph 7 of the Water Framework Directive.

In light of the above analysis it should be considered that the project will have no significant impact on the ecological potential JCWP Mouth Świna JCWP Szczecin Lagoon and JCWP Odra from Párnica to the mouth in terms of physical and chemical elements.

4.2.3.4. Water quality indicators determining the chemical status.

In the course of dredging work could be the release of priority substances and other pollutants listed in Annex 9 to the Regulation of the Minister of the Environment of 22 October 2014. on the classification of surface water bodies and environmental quality standards for priority substances ‐ which include both Microfouling inorganic and organic ‐ accumulated in sediments bottom.

In Tab. 48 is given in [42] concentrations of inorganic micro‐cadmium, nickel, lead, mercury ‐ included in the priority substances ‐ marked in the bottom sediment samples taken from the fairway. This table also contains the limits established for these substances in the Regulation of the Minister of Environment dated 11 May 2015. In the recovery of waste outside installations and equipment [51] and the limits and categories of hazards to the aquatic environment established in the CLP Regulation [54].

Concentrations above. inorganic micropollutants in sediments collected within a seaway does not exceed the specified limits for them. There is therefore no basis to conclude that the presence of these substances in the excavated material would be classified as causing a threat to the aquatic environment. Their eventual release in the course of dredging work will not have a significant impact on the chemical state JCWP Szczecin Lagoon as a whole.

As organic micropollutants determined by many organic compounds, usually characterized by a considerable biochemical stability in the environment. The most common of these are polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs). These include: a pesticides, surfactants (SPC), chlorinated organic compounds (CHZO), esters, alcohols, glycols, aliphatic and aromatic amines, phenols. A common feature of compounds of the groups

Structural are strong accumulation of living organisms, and bio‐magnification of the trophic chain.

The collected under [42] samples of bottom sediments of the water path in addition to the above mentioned contents. metals was determined as the concentration of polycyclic aromatic hydrocarbons, PAHs, polychlorinated biphenyls (PCBs).

The contents of the above. organic micro‐pollutants in sediments collected in the area JCWP Szczecin Lagoon and JCWP Odra from Párnica to the mouth do not exceed specified for them in the CLP [54] limits, and in many cases they are significantly lower than them. It can therefore be concluded that these substances have a limited adverse effects of biological or absence of the aquatic environment.

It should be emphasized that the allocation JCWP Szczecin Lagoon and Estuary Świna chemical status below good decided exceeding the annual average concentrations of tributyltin ether pentabromodifenylowego and octylphenol, while JCWP Odra from Párnica to the mouth ‐ exceeding the annual average concentrations of tributyltin.

Compounds of tributyltin (TBT) were used as an antifouling marine paints covering the bottom of the hull, and as an antifungal agent in the textile industry, in water‐cooling systems, as paper mills and breweries. Furthermore, either they used for the preservation of wood. At present, the use of TBT in antifouling paints and biocides is prohibited, while the concentration of these compounds in other formulations products or in any part thereof, may not exceed 0.1% by weight. However, tributyltin compounds ‐ for ease of sorb on particulates ‐ accumulated in bottom sediments and will unfortunately remain there for a long time. Distribution TBC to less toxic compounds mono‐ and dibutyl, because there is much slower than in bottom sediments in water. TBT in water is decomposed by light (photolysis), and micro‐organisms (biodegradation), hence the half‐life in this environment ranges from several days to several weeks. In contrast, under anaerobic conditions in sediments open bodies of water the half‐life of TBT is from 1 to 2 years, while in the bottom sediments collected eg. In ports, bays, estuaries up to ten times longer [59].

According to the CLP [54] tributyltin compounds are classified as dangerous for the environment and very toxic to aquatic organisms and may cause long‐term adverse effects on the aquatic environment (N, R50 R53 ÷).

Polybrominated diphenyl ethers (PBDE) are mainly used as a means of flame retardant materials [9, 59]. They are used in the production of building materials (primarily insulating foam), plastic parts for electrical and electronic equipment, marine and industrial coatings for the protection of container and furniture and automotive upholstery. They are stable compounds sparingly soluble in water, but exhibiting a strong affinity for fat, which are easily accumulated in living organisms. In the European Union prohibition on the use or placing on the market of pentaBDE and octaBDE, if the concentration of these compounds in the product preparation or exceeds 0.1% of the total weight and a ban on the use of decaBDE in electrical and electronic equipment.

Octylphenol (OP) are used in the manufacture of phenolic resins (used in the gum during processing in order to produce tires) and plasticizers

148

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

and antioxidants in the plastics and resins. OP poorly soluble in water, but readily sorb to the organic matter in sediments [59].

Taking into account the results of the chemical status JCWP identified and presented above characteristics of the substance determining the classification under this condition as well it can be presumed that in bottom sediments Świna estuary, Szczecin Lagoon and the Oder River to the mouth of Parnica are accumulated quite substantial quantities. In carried out on the project studies sludge [42], the contents of TBT, PBDE, and OP has not been determined, and it is not possible to determine whether the areas in which they will be carried out dredging those substances are present in amounts rendering the excavated spoil must be regarded as waste dangerous.

Nevertheless it should be noted that the Project also performed tests in order to determine whether the envisaged to select fairway sediments do not possess the properties and components in concentrations causing that they could be regarded as hazardous waste [55]. These analyzes were performed for the average of ‐ the three core samples taken from a depth of 0 ~ 2 m below the bottom ‐ sediment samples from the three points in the reference line in, ie. in km: 47.900 (JCWP Odra from Párnica to the mouth), 62.700 and 65.325 (Dig Mieleński). In these samples was determined content of metals (arsenic, chrome, zinc, cadmium, copper, nickel, lead and mercury), PAH and PCB and characteristics:

irritant H4 (pH) caustic (pH) infectious H9 (range: Clostridium perfringens, Salmonella sp., group coli, Pseudomonas aeruginosa). H5 harmful (in terms of acute toxicity to Daphnia, acute toxicity to fish) H6 toxic (in terms of acute toxicity to Daphnia, acute toxicity to fish) H14 ecotoxic (in terms of acute toxicity to Daphnia, acute toxicity to fish).

In [55] it was found that the obtained precipitates do not possess the properties and components in concentrations causing that they could be considered as hazardous waste.

It should be assumed that with displacement ‐ as a result of the Project under the dredging ‐ particles of sediment into the water column will desorption of TBT PDBE and OP, which may cause secondary pollution JCWP analyzed. Studies sorcji and desorption of the selected hazardous organic compounds ‐ with the above mentioned like. strong hydrophobic substances ‐ indicated [5], that by increasing the concentration of these compounds in water due to leaching of sludge in a short time, the re‐sorption and returning the water / sediments equilibrium. In the case of pesticides and polychlorinated biphenyls this state was achieved after approx. 4 weeks in the case of chlorophenols after approx. 2 weeks ‐ thereby confirming the high stability of combinations of these compounds from the sediment particles (strong hydrophobic 149

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

dredging intensity of the transition to the water, both cited above. of test compounds and TBT PDBE and OP will be limited. Notwithstanding the above, in order to minimize any secondary pollution analyzed JCWP indicated to limit the scrubbing process the particles sediment into the water column through the use of dredges equipped with a sealed collecting systems.

Possible increase in concentration of the above‐mentioned. inorganic and organic micro‐ pollutants listed in Annex 9 to the Regulation of the Minister of the Environment of 22 October 2014. on the classification of surface water bodies and environmental quality standards for priority substances, caused by dredging works, will have temporary and local character. After the termination of the work in a relatively short time will inherently return to the pre‐existing balance between the contents of the micropollutants in sediments and water. According to the Guidelines on exemptions from the environmental objectives [74], it should be considered that due to the fluctuations in water quality does not require the application of Article. 4, paragraph 7 of the Water Framework Directive.

In light of the above analysis it should be considered that the project will have no significant impact on the chemical state JCWP Mouth Świna JCWP Szczecin Lagoon and JCWP Odra from Párnica to the mouth.

4.2.4. Evaluation of the impact of the Project on protected areas.

4.2.4.1. Areas for the protection of habitats or species.

According to the developed in the [62] the method for setting targets of water bodies, the environmental objectives protected area identified on the JCW apply only to those sections of the body of water in which these areas are located, and not the entire body of water. These objectives may, however, have implications well beyond the protected area to which they apply, but only to the extent that is necessary for their achievements in this area.

In this volume the impact of the Project and the so‐called. related projects on individual species and ecosystems in the cards listed JCWP Mouth Świna JCWP Szczecin Lagoon and JCWP Odra from Párnica to the mouth based on the results of the inventory made for the Project [26].

JCWP Estuary Świna The card JCWP Mouth Świna indicated no areas for the protection of habitats or species for which the maintenance or improvement of water is an important factor in their protection.

JCWP Szczecin Lagoon The card JCWP Szczecin Lagoon listed a total of 12 areas intended, among others, to habitat or species for which the maintenance or improvement of water is an important factor in their protection, ie .: 1.

Fairway and their proximity is not the largest concentration of birds, such as are usually formed on areas defined izobatami from 0.5 to 5 m [39]. From Fig. 15 shows that the most abundant species present in the vicinity of the fairway are cormorants and mergansers, and thus primarily ichtiofagi. These birds are constantly exposed to disturbance. During the dredging project related impact will be severe. According to [39] does not provide, however, that it had a significant negative impact on the need to protect the SPA Szczecin Lagoon, due to the fact that the severity of this impact will be short‐lived and limited to a small ‐ in relation to the entire surface of the JCWP and SPA ‐ area. A similar nature will be occurring in the course of dredging, turbidity and release of the substance contained the sediments. The impact of this effect on the birds will not be significant, taking into account that they stay within a large, ‐ gutter outside of the track ‐ comparatively shallow tank, wherein during strong winds and odmorskich surges naturally occur re‐suspended sediment. Expected after the completion of the project a more intensive use of the fairway ‐ manifested primarily movement larger units ‐ should not cause a significant increase in enough noise that he threatened the whole SPA. wherein during strong winds and odmorskich surges naturally occur re‐suspended sediment.

The range of impact of the planned work will remain the following habitats:

1130 estuariesFor which is required as far as possible to preserve the natural and encapsulated flow, preservation of the natural processes of flow and mixing of fresh and salt waters and the exclusion of further antropogenizacji coastal zone ‐ The project does not provide housing outflow, will not cause a significant change in the natural processes of flow and mixing fresh and salt waters, Piast Canal and Canal Mieliński przekopami are artificial, for which there are no plans for further transformation of the coastal zone;

and species:

twaite shad, for which requires the presence of spawners and the presence of juveniles flowing into the sea, and patency of migratory routes from / to the sea - The project does not result in the loss of patency of migratory routes from / to the sea. At the beginning of the twentieth century twaite shad species it was relatively common in Szczecin Bay water [26]. There are records from that period describe his massive and very spectacular spawning strings. Last recorded twaite shad spawning the island Chelminek existed until the 50s of the last century, and the last recorded his strings were observed spawning in 1953 ÷ 1955. Currently, only occasionally caught are single specimens of that species. This does not exclude the possibility of the behavior of the modern twaite shad spawning grounds in the vicinity of Trzebież. The project does not interfere in this area Szczecin Lagoon. sea lamprey, for which is required to maintain patency of migration routes and conservation of the natural riverbed, including sediments, sections potentially spawning - The project does not result in the loss of patency of migratory routes from / to the sea and does not interfere in the sections of river beds that could provide spawning places; thick shelled river mussel, for which is required a riverbed or natural zrenaturyzowane, the natural structure of the DNA substrate, the concentration of nitrate ≤2mg / l N-NO3 - Design major undertaking, ie. dredging work will be conducted under degraded by humans as a result of daily use track associated with the movement of vessels, as well as periodic work carried out dredging, will not, therefore, a direct threat to this species benthos, due to the occurrence skójki gruboskorupowa in the area of the island Chelminek in [39] points to the need for the efficient carrying out dredging work in this area not to unnecessarily prolong the period of water turbidity.

In a special area of conservation (SAC) Estuary Oder and Szczecin Lagoon dredging will be carried out on the fairway, the construction of the island or islands of excavated material originating from that

dredging. SAC Mouth Oder and Szczecin Bay was created in order to maintain or restore the proper state, and protection of the following species of aquatic habitats and water‐ dependent:

1130 estuaries1150 Lagoons and lakes Przymorskie, 1230 cliffs on the coast of the Baltic Sea 1340 Inland salt meadows, pastures and rushes, 3150 oxbow lakes and natural eutrophic reservoirs, 3270 Sealed muddy riverbanks, 6410 fluctuating Molinia meadows, 6430 ziołorośliny mountain or riverside, 7140 Transition mires and quaking (mostly vegetation with Scheuchzerio‐ Caricetea), 91D0 bog woodland, 91E0 Łęgi willow, poplar, alder and ash. twaite shad (Alosa fallax) Asp common (Aspius aspius) lamprey (Lampetra fluviatilis), blow (Pelecus cultratus).

The range of impact of the planned work will remain the following habitats:

1150 As the coastal lagoons and lakes (coastal lagoons), Are required to preserve natural roads, rhythm and regime at least the occasional supply salty waters, salinity maintenance (optimally> 500 mg / dm3), the behavior of various plants (optimally at least 4 communities hydrophytes preserved occurrence stonewort); in a proper condition is acceptable natural eutrophy (transparency 0.5 ÷ 1 m, inorganic nitrogen 0.3 ÷ 6.5 mg / dm3 total phosphorus of 0.1 ÷ 0.5 mg / dm3 a pH of from 6.5 to 9) . The project will not change the rhythm and power of the regime salty waters of the Szczecin Lagoon. Will be preserved natural way to power. Construction of artificial islands for the implementation of one of the proposed variants (or variant thereof having one of three islands) will not have a negative impact on aquatic plant. This is due to their absence and unfavorable conditions for development in the planned location of artificial islands. [26] But can have positive character associated with the creation of new habitats for flora (colonization by species of reed islands, the emergence of halophilic species and / or subhalofilnych, macrophytes development in the coastal zone of islands) and fauna.

The creation of new islands will reduce the area of habitat coastal lagoon in 1150, which did not significantly deplete its resources, both in the Oder Estuary SAC and Szczecin Lagoon (approx. 369 hectares, or approx. 0.88% of the habitat), and in the country [39 ]. During storage refulatu may cause deterioration in transparency of the water and concentration changes of nitrogen and phosphorus (temporary increase in the level of eutrophication). This will be a negative impact on the habitat, but the short‐term (only during the construction of the islands). Both the proposed location, as well as the number and size of the islands and the material from which it will be built, should not interfere with the functioning of the habitat in the long term [26].

Project's impact on the species of waterfowl indicated in the card JCWP Odra from Párnica to the mouth in relation to SPAs Szczecin Lagoon is discussed in the section on JCWP Szczecin Lagoon. With tab. 50 shows that during the inventory of nesting birds in JCWP Measles from Párnica to the mouth of the only species identified in these species is the usual reed, users requiring water rushes reed. The project slightly interferes with the current state of the environment in this area. The total length of the so‐called. boundary collision is approx. 5.6 km, the sea defenses will be made only on the length of approx. 1.5 km. Possible spontaneous transformation of the shore (landslides) will concern only approx. 8.7% of the length of undeveloped shoreline currently JCWP Odra from Párnica to the mouth. It is estimated that this will cause loss of habitats for one pair of breeding ordinary Reed within OSO Szczecin Lagoon (the entire area of the Oder from Párnica to the mouth for a total of two pairs, including for JCWP 1). Ww. sea defenses will be made outside the JCWP Odra from Párnica to the mouth.

A special protection area (SPAs) Forest Goleniowska was created in order to maintain or restore the proper state of protection of the following water birds:

corncrake ordinary (crex crex ) Requiring preservation moisture exclusion and dewatering moist and wet meadows ‐ Draft does not disturb the current environmental condition in this respect, not refer to such areas; Ordinary crane (Grus grus) in need of preservation mosaic wetlands in the landscape, including the behavior of highly flooded zabagnień and exclusion of dehydration - Draft not impede significantly the current environmental condition in this regard, does not interfere because of wetland areas. While the destruction of rushes bordering SPA Goleniowska Forest, the coastal zone of the fairway, which has approx. 9.1 km, is expected to be only a length 165 m (approx. 1.8%) ‐ in the so‐called. collision boundary. It should be noted that these places remain in a natural state (without strengthening) will rebuild the rushes; ordinary white‐tailed eagle (Haliaeetus albicilla) Requiring behavior large and diverse complexes wetlands and water bodies rich in water birds, with little penetration of human behavior calm surface and edges of water as feeding site ‐ area of which the draft has long been used for shipping and a peaceful feeding site, while the project does not interfere in the basin adjacent to wetlands and reservoirs. The total length of the so‐called. boundary collision is approx. 5.6 km, the strengthening of the boundary will be made only to approx. 1.5 km. Possible spontaneous transformation of the shore (landslides) will concern only approx. 8.7% of the length of undeveloped shoreline currently JCWP Odra from Párnica to the mouth. Ww. sea defenses will be made outside the JCWP. It is estimated a traveler (Luscinia svecica) requiring behavior character bog habitat - Draft does not disturb the state of the environment in this area;

W within the limits of JCWP Measles from Párnica to the mouth portion special protection area (SACs) Mouth Oder and Szczecin Bay dredging will be implemented on the fairway. No significant effect of the project on the ecosystem of the lake in 1150 and Lagoons Przymorskie was shown in the section on JCWP Szczecin Lagoon.

Dredging in JCWP Odra from Párnica to the mouth may indirectly affect the coastal zone and part of the land. In the so‐called. Local collision edge (see Sec. 3) may cause the lower edge of the water. Self‐destruction will occur within those areas habitat of a szuwarowym (reed and sedge), forestry (Salix and alluvial ash‐alder) or zaroślowym (muddy bushes willow). It should be noted that the so‐called leaving places. collision boundary in its natural state (ie. without strengthening) will rebuild the above. vegetation.

W within the limits of JCWP Measles from Párnica to the mouth portion of the SPA Mouth Oder and Szczecin lagoon can lead to the destruction of habitats in the edge region with a total length of approx. 540 m (see Tab. 50).

According to [26] in the above. Mouth portion SPA Oder and Szczecin Bay ‐ ie. on the east bank of the Oder (Raduń) at the height of the island Karwasz small ‐ there is a small surface habitat 91E0 Łęgi willow, poplar, alder and ash. In accordance with the provisions of this tab JCWP habitats of these it requires: hydration (including, if applicable, the growth of inundation) normal from the viewpoint of the appropriate subtype (plant community), natural or nature zrenaturalizowany and hydrological regime streams if adjacent to carrs. The project does not interfere with the current state of the environment in this area. A possible loss of the habitat (see Tab. 50) would occur at the edge of a length of approx. 140 m.

Measles JCWP from Párnica to the mouth bordered by including, among others, Debina Radolin islands and a special area of conservation (SAC) Dolna Odra. Located in the peripheral zone of the habitat islands 91E0 Łęgi willow, poplar, alder and ash described in [26]. A possible loss of the habitat (see tab.49) would occur at the edge of a total length of approx. 1700 m.

Ww. loss of habitat 91E0 Alluvial willow, poplar, alder and ash surface, due to its winding up, will not affect significantly the surface of this habitat in the region and in the country. They do not disrupt the functioning of the alluvial occurring in the vicinity of the planned arrangements [26].

Planned Project and investment accompanying the construction, expansion or modernization of quays will be performed outside the above. Special Areas of Conservation.

From the above analysis conducted it shows that the negative impact of the Project and the so‐ called. investment occurring in the accompanying JCWP Szczecin Lagoon and JCWP Odra from Párnica to the mouth of protected species and ecosystems dependent on groundwater is quite limited. This is due largely to the fact that these projects will be implemented primarily in the areas of

179

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

already used economically and strongly transformed. In contrast, analysis and assessment made in the framework of the report on the environmental impact [39] led to the conclusion that the proposed modernization of the fairway, after the application of mitigating measures will not have significant adverse effects on items to protect Natura 2000 sites and will not violate the integrity of the network of these areas .

4.2.4.2. Areas for recreational purposes, including bathing.

There is no reason to believe that the project will adversely affect the JCWP located in Lagoon Szczecin Mouth and JCWP Świna bathing or will be an obstacle to their formation. JCWP mentioned are used for recreational purposes, and the planned modernization of the fairway will not cause restrictions in this regard. Measles JCWP from Párnica to the mouth, due to economic use, not intended for recreation or bathing. It is, however, relatively intensively used for sailing yacht and motorboat. The planned modernization of the fairway will not cause restrictions in this regard.

Project implementation, the use of mitigating measures, is therefore not a threat to the achievement of environmental objectives for protected areas within the boundaries of JCWP Mouth Świna JCWP Szczecin Lagoon and JCWP Odra from Párnica to the mouth.

4.2.5. Conclusions.

The project generates effects that exacerbate existing or introduce new changes in the hydromorphological JCWP Szczecin Lagoon and JCWP Odra from Párnica to the mouth can worsen the ecological potential of these bodies of water failing to achieve or threaten their water environmental objectives of the Water Framework Directive.

Therefore, it is necessary to assess the possibility of applying derogations (derogations from the environmental objectives) Article. 4 paragraph. 7 Water Framework Directive. The assessment should be carried out by verifying the conditions for determining the establishment of such a derogation contained in Article. 4 paragraph. 7 and with reference to Article. 4 paragraph. And Article 8. 4 paragraph. 9 of the Directive.

5. Design Assessment for fulfillment of the conditions referred to in Article. 4 paragraph. 7 WFD.

Environmental objectives may be subject to exemption, provided certain conditions are met Article. 4 paragraph. 7 Water Framework Directive (WFD). The scope of these exemptions include the new changes the physical characteristics of surface water or changes in the level of groundwater bodies, or do not prevent deterioration of the status of surface water bodies (From good to very good) as a result of new forms of sustainable human development activities. .: The project entitled "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" is within this range. Carried out following analysis is to verify that it fulfills all the conditions set out in Article. 4 paragraph. 7 Water Framework Directive.

Have you taken all practicable steps to mitigate the adverse impact on the status of water bodies?

For the purposes of the Water Framework Directive practical steps means any measures that are technically feasible, are not associated with disproportionately high costs and are suitable from the point of view of the new modification or sustainable human activities.

Whereas the goal of the project, made detailed analysis and research on determining its scope so that it introduced new modifications to the physical characteristics of the exit section of the Oder, the Szczecin Lagoon and the Strait Świna ‐ based on the modifications made in the past ‐ were the least possible interference in the environment or have been this environmentally preferable. This applies in particular to the proposed gauge, and the intended method of development spoil originating from deeper fairway.

The width of the modernized fairway is designed so that at the least possible interference in the line of the Oder were obtained appropriate and safe conditions for sailing ships laid down on the track.

As variants development spoil originating from deeper fairway creation area indicated Szczecin Bay artificial islands (islands) The resulting environmental benefits are extensively discussed in [26, 39]. These islands will have a positive impact on the biological elements to be taken into account when assessing the status of water bodies, namely: – Underwater part of the strengthening of the coasts of islands will constitute the habitat of "artificial reef" among zasiedlanej the new colonies of zebra mussel Dreissena polymorpha variable ‐ mussels are preferably impact on water quality, reducing its turbidity and blooms and creating additional habitat for other invertebrates,

181

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

– varied coastline of islands facilitate the development of aquatic vegetation and / or rush, which will contribute to the creation of a mosaic of habitats for more species than currently exist in the region, – formation of a new adjacent islands, different from the previous syndrome, benthos can attract other species of fish – change of currents in the Lagoon, including leading to reduce the deposition of organic matter may lead to the presence in that area of new valuable species with higher environmental requirements, for example. skójki gruboskorupowa.

Within [69] also provides a number of measures aimed at reducing the adverse impact of the Project on JCWP Szczecin Lagoon and JCWP Odra from Párnica to the mouth:

used for deepening the fairway and spoil deposition equipment and technologies to minimize the extent of turbidity of the water and suspended sediment spread; the introduction, due to the need to secure the migration of fish and lampreys, term limits and time for the dredging and the obligation to perform such work under the supervision of environmental. And yes: – dredging in Roztoka Oder (ie. from approx. 36,000 km to approx. 45,000 km of track) and Mielińskim channels and Piast (ie. from approx. 5,100 km to approx. 17,500 km) during the period 01.10. ÷ 31.05. will not be carried out during the night (22: 00 ÷ 6: 00). Working in the period 01.10. ÷ 31.05 outside these hours must absolutely be done under strict environmental supervision (including ichthyological). In the remaining period, ie. 01.06. 30.09 ÷ dredging work can be performed without time limits provided environmental surveillance, – dredging in the rest of the track can be performed throughout the year, indefinitely, provided that an environmental supervision; carrying out dredging work on another, separate sections of the track from beginning to end as soon as possible, which means a one-time intervention in the bottom of the section after which it can be gradual and not interfere with subsequent interference in the bottom macrozoobenthos reconstruction. This applies, in particular, the region Chelminek Island, where there is a protected species benthofauna - thick shelled river mussel (Unio crassus); avoiding dredging in periods of backwater and northern and northwestern winds, which will limit the spread of suspended sediments in the top of the Oder, filling the existing channels Mielińskim trims and Piast Dredged materials derived from dredging works on the fairway; introducing the possibility of temporary suspension of the works in the cases of high-risk environment, especially fish and lampreys;

182

leave ‐ where possible ‐ places where the slope widened and deepened track interfere with the natural coastline of the river Odra (ie. the boundary collisions) without strengthening, which will retain the existing habitat or give them the opportunity to rebuild; not removing the coastal zone of the track on the section between Szczecin and Police, and the fugitive him channels, existing windfallen trees and tree roots, which will keep the animal refuges from different taxonomic groups; use to strengthen the banks of mainly natural materials, how to the least interfere with the environment and properly blend into the existing landscape; the exercise of artificial islands in the Lagoon under environmental supervision; conduct all work in a way that avoids water pollution and to minimize the consequences of the possible occurrence. And yes:  during the execution of dredging will be conducted constant supervision over the work of machines and their constant revisions in terms of technical efficiency, in order to avoid uncontrolled leakage of fuel and lubricants to the water,  will be introduced duty cleaning contaminants from the surface to drop out in the course of dredging works (eg. the branches, vegetation water, the old wooden structures, fishing nets, etc. residues.)  floating equipment used will be equipped with devices for collecting possible leakage of petroleum products from water surface,  in the event of leakage of oil to water will be applied to the mechanical collection from the water surface and absorbents,  in the case of filling material oil and petroleum using the corresponding means to prevent the entry of harmful substances into the water,  domestic waste during the construction phase will be collected in cesspools installed on vessels and received by specialized companies.

Is the cause modifications or alterations are specifically set out and explained in the river basin management plan for the river basin district required under Article. 13 WFD and the objectives are reviewed every six years?

The program was included in the renovation project water management plan in the area of the Odra river basin [81]. Public consultation of this document have been completed on 22 June. The final version, in force for the years 2015 ÷ 2021 is to be ready by the end of the year.

Is the cause modifications or alterations are of overriding public interest and / or benefits to the environment and to society of achieving the objectives of water protection are outweighed by the benefits of the new modifications or alterations to human health, the maintenance of human safety or to sustainable development?

Analysis of the socio‐economic and development opportunities and the region of Western Pomerania, confronted with the Union's policies, national strategies and expectations and social needs, indicates that the execution of the project entitled .: "Modernization of Swinoujscie‐ Szczecin to a depth of 12.5 m" speaks

socio‐economic development of the Szczecin Metropolitan Area and the region of western Pomerania

which should be regarded as an overriding public

interest. Implementation of this project will in fact:

Improving the availability of transport, and thus the competitive position of ports in Szczecin, Swinoujscie and Police,

Globalization of production and consumption is increasing trade and increased demand for transport services. Trucking ship high capacity / capacity contributes to significant savings in the cost of transport of goods, and thus to increase the efficiency of trade. Inadequate to the increasing size of ships the port availability prevents the reduction of the average costs of transport, and thus streams of goods are directed to other ports, ensuring the achievement of such benefits. As a result, the port loses traffic, transhipments and sizes supported trade. A decrease of the economic importance of both the port and other transport links in the chain. Is slowing down socio‐economic development of the whole region.

Increasing the attractiveness of ports in Szczecin, Swinoujscie and Police, will result in the development of both ports as the entire sea‐land transport chain that runs through the Szczecin and Swinoujscie further inland and to the south of Europe and Scandinavia.

Szczecin is an important transport hub in the Central European Transport Corridor CETC‐ ROTE65. It is expected that the improvement of accessibility for maritime transport will stimulate investments in new quay, logistics and warehousing centers and so. port facilities. These investments are already being prepared. Their execution will be justified only in the case of a seaway Swinoujscie‐Szczecin relevant technical parameters. This concerns in particular the investment ‐ defined in this study as accompanying.

184

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

Increasing the attractiveness of the region of West Pomerania as a place to invest and locate new businesses.

The consequence will be:

1. long‐term increase in the amount of goods and trade efficiency, thus increasing income from this source; 2. a significant increase in jobs ‐ mainly in the maritime economy, transport and logistics; 3. increase in spending of companies and workers of the port sector and transportation incurred for the purchase of external services and materials supply in other sectors of the economy of the region and the country; 4. stimulate the development of other sectors of the economy in the environment, in particular in the Szczecin Metropolitan Area and the West Pomeranian region, 5. improvement of the financial situation of municipalities through additional tax revenues, which will be able to be allocated eg. on the financing of public services that meet the needs of residents, 6. reducing the negative environmental impact of transport ‐ less pollution resulting from the use of transporting large quantities of goods by water, instead of transporting them by road smaller batches.

Is the beneficial objectives served by those modifications or alterations of the water body can not for reasons of technical feasibility or disproportionate cost be achieved by other means, which are a significantly better environmental option?

Failure to deepen Swinoujscie‐Szczecin to 12.5 m is that, to achieve similar socio‐economic benefits in the West Pomeranian region, loads equivalent to projected as a result of the planned investment growth of cargo handling in the port of Szczecin would have to be unloaded in the port of Swinoujscie and then transported to the Szczecin (and deeper into the country, according to their intended use): overland by car or by train waterway vessels using a smaller capacity.

There would also be a reverse situation ‐ goods supplied to Szczecin will have to be transported to the port of Swinoujscie and only there loaded onto large ships.

In the case of road transport would mean a significant increase in traffic on the route from Swinoujscie to Szczecin (national road S3) and the associated inter alia, increase in emissions and an increase in noise level. The need to transport approx. 2.87 million tons of cargo per year ‐ equivalent to projected growth of cargo handling in the port of Szczecin ten years after the completion of the Project [58] ‐ causes for the appearance on the tour additionally approx. 262 30‐ton trucks daily. A further expected in [58] after the next

185

The impact assessment of the project entitled. "Modernization of Swinoujscie‐Szczecin to a depth of 12.5 m" on water resources

ten years, the growth of cargo to approx. 6.94 million tonnes will require a further 371 above. trucks a day. So significantly greater truck traffic especially in summer, when tourist traffic is increased, will provide additional difficulties (traffic jams, less security on the road) for both the local community and visitors. It should be emphasized that the road section S3 Swinoujscie‐Szczecin runs partly through protected natural areas, including Wolin National Park and its further development (increased capacity) will most likely not possible. The negative impact on the environment will also have a faster destruction (wear) of the existing road infrastructure and the need for more frequent modernization works connected with it (eg. replacement of damaged road surface). Replacement of water transport by road transport is therefore broadly defined environment for the solution far worse.

Unfavorable to the environment, to a lesser extent, the situation would also have occurred in the case of transport of the above. the amount of cargo between Swinoujscie and Szczecin by train.

It not without significance is the fact that the water transport generates the lowest external costs, thereby minimizing its harmful effects on the environment. According to [18], the corresponding energy consumption for transportation of 1,000 tons of cargo at a distance 1 km is at the level of 20 kWh for water transport 45 kWh for rail transport and 122 kWh for road transport.

Replacement of transport water in the section between seaports Swinoujscie and Szczecin by trucking or rail ‐ depending on the type of cargo transport to the place of further purpose ‐ may require still one further transhipment. Economic analysis [18] indicate that at distances of less than 120 km, the transportation is broken unprofitable.

If desired transport larger quantities of cargo in a port in Szczecin by water transport, allowing the depth of the transit Swinoujscie ‐ Szczecin the current level will be associated with increased movement of the smaller vessels. This will have a negative impact on the wider environment. Can be a hindrance in ferry traffic in Karsiborze and urban crossing in Swinoujscie. May cause limitations in the development of water tourism in the estuary of the Oder.

In Tab. 51a and Tab. 51b summarizes the environmental costs of commutation from the port of Swinoujscie and Szczecin Police 1,000 tons of goods by various means of transport. These costs were estimated using "external cost calculator", recommended by the European Commission when proposing a transport projects [8]. It identifies individual marginal external costs of different modes of transport, which calculated the loss of others due to environmental degradation, loss of time and loss of other values indirectly related to the transport of 1,000 tons of cargo on the route 1 km away. They included: air pollution, climate change, noise, accidents, racing. Ww. costs were determined on the basis of data from 27 European Union countries.

With these tables it is clear that the use of maritime transport in the estuary of the Oder will generate the lowest environmental costs of commutation of cargo ‐ approx. 1.5 ÷ 3.5 times lower than the station, approx. 4 ÷ 5.5 times lower than the inland waterway and up approx. 6 ÷ 13 times lower than the car.

Within [58] estimate the savings made in the above. external costs that occur during the period of 2021 ÷ 2041 as a result of the Project. They are obtained as a result of:

shortening the distance of transportation in sea‐land part of the land transport chain running through the port in Szczecin and modal balance changing the structure of the operation ‐ respectively 93.83 and 353.32 m zł million zł. shorten the distance in the sea transport section above. transport chain ‐ approx. 237.55 million zł.

Given the above it should be considered that there are other measures that would constitute a significantly better environmental option for obtaining beneficial objectives, which are modifications of surface water bodies: PLTWIWB8 Szczecin Lagoon, Odra PLRW6000211999 from Párnica to the mouth.

Is the use of derogations does not exclude or compromise the achievement of the objectives of the WFD in other bodies of water within the same river basin district?

The use of the derogation of water bodies PLTWIWB8 Szczecin Lagoon and PLRW6000211999 Measles from Párnica to the mouth does not preclude achievement of the objectives Water Framework Directive other water bodies in Oder catchment area.

These JCWP part of the Oder estuary. Planned upgrading fairway can cause a change in distribution of the total volume of water outflow from the lagoon to the Baltic three strait. This should not, however, this change should not hinder the achievement of the objectives of the WFD in other appointed at the estuary of the transitional water bodies. The deterioration of ecological potential concern in terms of macrozoobenthos will concern only PLTWIWB8 Szczecin Lagoon.

Deepening and widening of the fairway Oder‐Przekop Mielenski may cause changes in the section of flow in the river network Parnica lower Oder below, which is, but this should not interfere with attainment of the objectives environmental homogeneous parts of river water above it.

Is the use of the derogation guarantees at least the same level of protection as the existing Community legislation? / Whether the project is consistent with the implementation of other Community legislation on environmental protection?

The use of the derogation in relation to water bodies: PLTWIWB8 Szczecin Lagoon and PLRW6000211999 Odra from Párnica to the mouth will guarantee at least the same level of protection as the existing Community legislation. The project is consistent with the implementation of other Community legislation on environmental protection. This issue has been examined in detail in the Report on the environmental impact [39].

With this in mind it should be considered that the project entitled .: "Modernization of the fairway Swinoujscie‐Szczecin to a depth of 12.5 m "meets the conditions of Article. 4 paragraph. 7 Water Framework Directive concerning the applicability of the derogation.
