3. PROJECT DESCRIPTION
3.1. Project Title
Construction of Adjud Municipality Bypass.
Phase: Feasibility Study
3.2. Location
There are two solutions for the location of the By-Pass for Adjud Municipality, as follows: either the West location, or the East location, on the superior terrace of Trotuş and Siret Rivers.
3.3. Achievement and Operation of Scheme
The period of execution proposed for the bypass of Adjud municipality is one year. The operation time and schedule of the scheme is not limited.
3.4. Investment Opportunity
Adjud Municipality is located in the North-East area of Vrancea County, in the upstream of the confluence of Siret River with Trotuş River. After Focşani municipality, Adjud is the second center of interest in the county.
Adjud Municipality is situated at the junction of the following road directions: on the East to Oneşti municipality, on the North to Bacău and Suceava municipalities and the other adjacent cities and villages.
The national road DN2 that crosses Adjud city from South to North is located in the meadow area of Siret River, linking the localities situated in the South of Adjud, such as Mărăşeşti, Focşani, Buzău, Ploieşti, Bucharest, with the localities situated in the North: Bacău, Paşcani, Suceava.
Numerous county roads and village roads, modernized or not modernized, start from Adjud municipality, linking the villages and communes in the area with the municipality. Adjud is a link node between the municipalities Focşani and Bacău, and has road connections with the adjacent localities, by the national roads and village roads that cross over its territory: - DN1 to the South – East (Adjud – Turda) - DN2 both to Focşani and to Bacău – Suceava - DN11 to Oneşti and to Podu Turcului - Dc21 to Adjudul Vechi Presently, the transit traffic is developing exclusively by crossing the municipality, including the center area. Note that the city streets are narrow, not entirely modernized; resulting traffic congestions in the railway station area and in the
5
northern exit area (especially the road to Oneşti municipality), narrow junctions, small radius curves, etc.
These factors cause difficult traffic conditions, degrading and wearing the road structure on the existent main roads as a consequence of the overstress resulted from the heavy and intense traffic, increasing the number of accidents, the significant environmental pollution on the entire surface of the central area of the city, besides framed on both sides by habitation buildings.
The traffic increase together with the improvement of traffic safety raise the necessity of black spots elimination over this section through the construction of a bypass that will make the connection between national, county and local roads and will lead to: - increase of traffic capacity by the improvement of traffic flow; - elimination of municipality traffic jams; - development of a comfort plan for the road users; - increase of traffic safety; - reduction of accident number; - improvement of municipality environment through the reduction of NOx and sonic pollution;
The two solutions have been discussed in the meeting of the Technical Economical Commission (CTE) of NAR Bucharest, the most convenient solution to be accepted and evaluated in the phase of Feasibility Study and then to be detailed in the Working Drawings phase of the Technical Design.
3.5. Project Description
This chapter presents briefly the two solutions, presented and discussed to the meeting of CTE – NAR Bucharest, respectively to the Council of Vrancea County:
The possible solutions for the by-pass, having the lengths of approx. 5.3 km, respectively approx. 7.8 km, are the following:
Solution 1: In the East of Adjud Municipality, on the location of the future Motorway Ploieşti – Sculeni = 7.8 km.
Solution 2: In the West of Adjud Municipality, on the location the future Motorway Ploieşti – Sculeni = 5.3 km, with two possibilities: Sub-Solution 1, with approach into the city by the interchange designed on DN 11A. Sub-Solution 2, with 3 roundabouts for approach into the city.
This Project has the objective to improve the traffic conditions and the environmental conditions in Adjud municipality, as well as to regulate the traffic, to decrease the noxa agents’ concentration reducing the air and noise pollution resulted from traffic.
6
The deviation of transit traffic from DN2 shall radically release the traffic in the central area of Adjud municipality and also on the DN2 routes on the direction Bacău – Focşani, from DN11A on the directions Oneşti – Bârlad.
Two possible solution have been studied: Solution 1: In the East of Adjud Municipality, on the location of the future Motorway Ploieşti – Sculeni Solution 2: In the West of Adjud Municipality, on the location the future Motorway Ploieşti – Sculeni.
Solution 1 – East Solution
The fields existent around Adjud city are plane and cultivated with cereals, and only after approx. 3 km out of the city appear the crests of the hills along the route of DN 2 to Sascut – Bacău.
The route of this by-pass, as national road, detaches from DN 2 to the right, after crossing Trotuş River, by a roundabout with Rext.=30.50m to the right, then overpasses the railway Bucharest – Suceava, continues to the North on the same location with Moldova Motorway, up to the area of Cellulose & Paper Factory VRANCART.
After crossing Trotuş River, the by-pass inscribes, on the first 2.00 km, close to a secondary railway with access to marshalling yard Adjud, outside its safety area, where is also a stone paved road, then on the next kilometer it inscribes into the East side of the marshalling yard, continuing the next 3.00km, at the periphery of Vrancart Factory.
From this point, the by-pass is turning to the left, crosses the two overpasses existent on the county road Adjud – Adjudul Vechi and then inscribes on a designed location, perpendicular on DN2, returning to DN2 by a roundabout, in the same point where the West Solution of by-pass also returns to DN2.
To allow the access in DN 11A there will be required a road link to DN 2, of approx. 600m length, this link detaching from DN 11A before the entrance in Adjud, and the connection to DN 2 to be at the exit from Adjud, to Bacau (before the overpass for the railway Adjud – Onesti).
The length of this solution of by-pass, by the East, is approx: L=1.5+4.1+1.6=7.2km.
Taking into account the link with DN11A, the total length is: L=7.2+0.6=7.8km.
Starting from the principle mentioned at the beginning, that the By-Pass for Adjud Municipality must become, in the future, the first lane of Moldova Motorway, can be demonstrated that by this location (the East Solution) the by-pass shall not require additional investments, and the works executed for the by-pass shall be totally included into the Motorway.
7
Solution 2 – Solution West
This location is located in the West side of the city, the most part being situated in the meadow of Trotuş River.
The West Solution detaches from DN 2 after crossing Trotus River by an alignment of 1.5km length, from the national road curve to the left, having R = 500 m.
By a curve to the right, having the radius of approx. 1200 m, the route continues to DN 11A, crossing it with another alignment, at approx. 300 m before the entrance in Adjud. This last alignment, extended, crosses the existent axis of DN 2 before the ramp foot of the overpass for the railway Adjud – Onesti.
The length of this solution, by the West of Adjud, is approx. 5.00 km.
Not that the actual DN 2, at both entries to Adjud municipalities, becomes an auxiliary road and links to the solution of by-pass by roundabouts, with Rext=30.50m. Similarly shall be treated the junction of this solution with DN11A by a roundabout.
The above information leads to the question of carrying out only one entrance and only one exit to Adjud, and for this reason the West Solution has 2 Sub-Solutions. Sub-Solution 1 where the access to the municipality is carried out by only one point, more precisely by an interchange designed at the junction of by-pass with DN11A. Sub-Solution 2 where the accesses in the municipality are carried out by 3 points arranged as roundabouts: in the South at the detaching point from DN2, in the West at the junction with DN11A and in the North at the point of returning to DN2.
The approval of one of these two sub-solutions must take into account the conclusions of the public consultation, also considering the point of view of the local authorities and of the National Company of Motorways and National Roads in Romania. The length of the West Solution of by-pass is 5.3 km.
If the West locates the Moldova Motorway, only 2.7km of the by-pass shall be included, compared to the East Solution, also specifying that the optimum location of the future Motorway, from Focsani direction, is between the railway Bucharest – Suceava and Siret River: - Two overpasses: over the railway Focsani – Bacau and over DN2, in the South - Skew bridge over Trotus River and not a normal bridge, like in the East Solution - Three overpasses, over: DN2, railways Adjud – Onesti and Adjud – Bacau
Note the route complexity and difficulty as concerns the geo-morphological conditions and natural obstacles, as well as transport ways (roads and railways) characteristic to the entire area proposed for the execution of by-pass for Adjud municipality – important railway node, situated between the river beds of two large rivers: Trotuş and Siret.

4. EXISTING SITUATION
4.1. WATER
4.1.1. Surface Water
Surface Waters Condition
Internal Rivers Condition: - Hydrographical network total length: 1756 km - Length of water courses monitored for quality: 638,3 km from which, on quality categories, according to STAS 4706/1988: Category I = 83 km Category II = 339,3 km Category III = 56,8 km Category – degraded =159,2 km.
Physical and Chemical Qualities for Surface Waters, according to the Basic Norms for Quality
The following table presents the quality category for water courses in the area of interest, in the monitoring sections:
Quality Category Crt Water Supervision No Course Area Coli-Bacilli RO GM TS GEN C% mg/l
1 Siret Adjudu-Vechi II I II II 51,7 50.000
2 Trotuş Adjud II I II II 47,5 227.250
Physical and Chemical Qualities for Surface Waters, according to the Norms for Piscicultural Waters
According to STAS 4706/1988, the watercourses in natural state or arranged, natural and storage lakes, classify in 3 quality categories (I, II, III) as concerns the domain of utilization.
The waters of Quality Category I, along with other domains of utilizations (drinking water, breeding, alimentary industry, irrigations, swimming pools, etc), are also used for the reproduction and development of salmonoids, as well as supplying with water the salmonae piscicultural arrangements.
9
The waters of Quality Category II are used in the domain of reproduction and development of natural piscicultural base, as well as for supplying the water to the piscicultural arrangement, with the exception of salmonae arrangements.
Siret River is inscribed in this category of quality, after the entrance in the county to Adjudu – Vechi and up to the confluence with the Danube River on 189.3km, as well as Trotuş River, on 14km.
4.1.2. Underground Water
The monitoring of underground waters quality is carried out by the network of observation boreholes, the physical and chemical analyses being performed once a semester, by exploitation – captures and boreholes for supervision near the industrial platforms.
Concentrations determined on Supervision Boreholes:
Indicators Crt. Sampling Hydrographic Borehole No. Location Basin Code 2+ NO3 Fe 0 1 2 3 4 5
F1 - 0,29 1 Adjudu-Vechi SIRET F7 85,1 0,31 F8 54,1 1,13
For the underground sources (that represent the main water supply source), the only operation for water treatment is the chlorination with gaseous chlorine at the Purification Station Suraia – Focsani and “Water House” Adjud.
4.2. AIR
Air Quality in the Area
In the Report for the Environmental Impact Evaluation Study, the air quality in the bypass route area is based on the data from the local authorities for environmental protection.
As concerns the emissions, the gases with greenhouse effect (CO2, CH4, N2O, NOx, CO, NTM, COVNM) at the level of the county result mainly from the industrial activity, the road transport having a significant influence only for the SOx emissions.
The emissions of NOx resulted from road represent approx. 20.5% of the total emissions of the county and the emissions of NMVOC, CO, CO2 and N2O represent approx. 5 – 8% of the total.
10
The emissions of CH4 and NH3 resulted from road transport are insignificant at the level of emissions for the county. Based on the tests carried out by A.P.M. on air samples taken from the area of Adjud municipality, for which NH3, NO2, SO2 and total powders in suspensions were determined, with the exception NH3, all the maximum admissible limits have not been exceeded. As far as the heavy metals are concerned, the lead has recorded the highest level in the county, which is approximately 90% from the road traffic. Based on the measurements carried out by A.P.M. Vrancea, it was established that the concentration of lead from the particles in suspension that were taken from the air does not exceed the maximum admissible limits. Generally, the air quality in Vrancea County is good.
For NO2, SO2 and sedimentary particles the annual average concentrations were not exceeded. An exception is the indicator of sediment powders, for which the CMA values were exceeded in the point of Public Fields Administration Ramnicu Sarat, the cause being the very intense road traffic. In addition, based on the measurements carried out there was no record of acid rainfall on the county territory. In order to get information regarding the air quality on the bypass route, were used the measurements and the observations done by NAR near Adjud locality. The chemical indicators specific to the road transport activity, respectively SOx, NOx; ammoniac and total powders in suspension have been analyzed. Based on the analysis of the laboratory test results it was observed that the concentrations of air pollutants from the designed road area are way below the maximum admissible limits.
Thus, SO2 and NO2 are 4 – 6 times under the CMA, the ammoniac was not identified and the total powders in suspension are approx 5 – 8 times under CMA.
4.3. SOIL
4.3.1. Aspects regarding the Quality and Use of the Soils in the Area
The present conditions of the SOIL environmental factor is stressed in the chapter hereby through the laboratory tests carried out by ICIM on samples taken from the road area.
The tests carried out on the soil samples were aimed to identify the pollutants specific to the road traffic, especially the metals and petroleum products, in order to create a reference in the monitoring activity.
11
The soil samples have been taken from the by-pass designed location.
On the logs, along with the values resulted for the pollution indicators in analyze, are also mentioned the admissible values (MAC, according to the Order No. 758/1997).
Note that all the analyzed parameters are situated much below the admissible limits that are specific to the soil pollution.
The pollutants concentrations inscribe in the normal values for soil.
The lead and oil petroleum products from the by-pass route inscribe in the normal values for soil.
In the road area, the soil quality is affected by the following factors: - Lower local fertility - Erosion grade in combination with landslip areas - Green pollution by weeds grown on the fields remained without cultures - Industrial pollution on limited areas - Strictly limited pollution in the perimeter of some disaffected zoo-technical farms.
4.4. BIO-DIVERSITY
4.4.1. Vegetation
The wild flora of Vrancea County includes 1375 species and 99 sub-species of superior plants, of 109 families and 515 types, from which 34 are ferns, 9 are gymnosperms and 1332 angiosperms.
Geo-botanically, the most part of the county is included into the Euro-Siberian Region, with: European East-Carpathian Province and the Circumscription of Moldo- Transilvanian Flis in the mountain area and the Balkan–Moessic Province and Circumscription Southern Moldova in the hilly area.
The field area is included in the Iran – Turanian Region with Ponto–Sarmatic Province and the Field Circumscription Baragan – Inferior Siret.
Referring to floristic, there have been identified over 150 vegetal associations, and in the mountain and hilly areas we note numerous endemical species such as: Aconitum moldavicum, Campanula carpatica, Cardamine glanduligera, Chrysanthemum rotundifolium, Dianthus kitaibelii ssp. spiculifolius, D. tenuifolius, Hepatica transsilvanica, Poa nemoralis ssp. rehmanni, Ranunculus carpaticus, Sesleria heufferiana, Symphytum cordatum, Thymus comosus, as well as natural monument species: Taxus bacata, Leontopodium alpinum, Cyprypendium
12
calceolus, Trollius europaeus, and in the field area: Fritillaria meleagris (identified in the year 2000). Generally, the state of wild flora corresponds to stational conditions.
The most natural grade aspect is assured by the forestry, pluriene brush, of natural – fundamental type in the mountain and hilly area, where the damage produced by the meteo-climatic and biological factors are insignificant (breaking and pulling down by wind and snow, drought, sickness and pests), compared to the artificial brushes drawn out from the natural habitations, such as pine cultivated on plain.
The by-pass of Adjud Municipality crosses several agricultural fields and pastures.
4.4.2. Fauna
The wild fauna of vertebrates is specific to the habitats of trans-palearctik area, among which: 40 species of mammals, 220 species of sedentary birds, of passage, winter and summer guests (53 are nestling), 9 species of reptiles, 12 species of bathrachia, 32 species of fish, mentioning that the effectives of mammal fauna are maintaining in constant limits.
Referring to birds, we note the disappeared big birds of prey: Gyps fulvus, Aegypius monachus and Aquilla crysaetos, the reduced effectives of insectivore birds in the plain habitats, strongly anthropized as a consequence of mechanization and chemicals used in agriculture, as well as the reduced forestry brushes in the area. Note the disappeared specie of bustard (Otis tarda), considered monument of nature.
The aqua-fauna is distributed on zones: - The superior course of the rivers of Vrancei Mountains is the trout area, where the anthropic impact is minimum - The middle course of the rivers is the barbell area, with predominant negative impact resulted from domestic dumping - In the inferior section (broad snout area) the pollution results from the residuals of zoo-technical and industrial activities.
In the forests of Vrancea county live the following species of animals: bear, lynx, marten, boar, hart, deer, grouse, squirrel, salamander, mountain lizard, common viper, Carpathian salamander, pheasant.
4.4.3. Natural Habitats, Natural Reservations
Among the natural habitats left we mention the following: fresh water habitats, grassland and shrubbery habitats and forest habitats.
13
The biocoenosis of the ecologic system of the area has suffered a major transformation along the years resulting in the replacement of spontaneous forest vegetation by agricultural crops in the process of natural system substitution.
As concerns the quality aspects, the agriculture cultures are reflected by one dominant specie, with secondary weed species found mainly on the margins of approaches around the cultivated parcels.
The weeds specific to the area, growing on the margins of cultivated areas and also penetrate into the crops are: the thistle (Onopordon acanthium), the wormwood (Artemisia absinthium) and graminaceae species such as Agrostis, Calmagrostis, Corex.
The main species of spontaneous flora from the agricultural crops are: Bromus sterilis, Bromus squarrosus and Aegilops cylindrica together with: Asparagus officinalis, Ballota nigra, Anagallis arvensis, Cirsium vulgare, Canabis ruderalis, Centaurea diffusa, Papaver rhoeos.
The areas of natural pastures are generally small including the same species of herbaceous dominated by Botrichloa ischaemum.
On the more steep slopes there is a natural vegetation which includes species like Fetusca vallesiaca and other herbaceous species like: Allium taurium, Stipa capillata, Poa bulbosa, Solanum dulcamara together with some wooden species: Morus Alba, Acer tataricum, Ulmus.
The terrestrial fauna of the agricultural ecosystems in the designed road area include the representative elements specific to forest areas together with the species that occurred due to the agricultural crops.
4.5. LANDSCAPE
The area around Adjud municipality is a plane area, alternative with small depressions of hilly relief, having a varied restorative landscape.
The landscape is dominated by the alternant cultures, giving varied colors.
The construction period is a stage with a limited duration therefore the natural equilibrium and the landscape will be improved after the completion of works. Therefore the landscaping works are not required during the construction stages.
Resinous trees and shrubs, which maintain their green foliage all the year, and dedidous trees with falling leaves, which have the advantage of seasonal chromatic variation, represent the vegetation proposed for the landscaping.
The main issue of landscaping works is the grass seeding. The grass strips on both sides of the route in the safety area form exclusively the vegetal scenery. They cover the embankments and have an important role in the soil stabilization. The
14
grass areas also make evident the shrubs. In addition, the horizontal areas from yards and parking lots are proposed to be lawns with trees and shrubs.
4.6. SOCIAL AND ECONOMICAL ENVIRONMENT
4.6.1. Demographical Data and Population Health
As size, Adjud Municipality is the second in the county, after Focşani Municipality and consists of the locality – called Adjud plus the localities included in Adjudul Vechi, Şişcani and Burcioaia, having a number of 21200 inhabitants.
The density of population in the administrative territory is 103.58 inhabitants/km2. This value shows that the population is denser than in the other cities of Vrancea County, with the exception of Focşani city, and than the national average of 95.8 inhabitants/km2.
The population average age in Adjud city and the afferent localities is 30.3 years for men and 32.6 for women, values representing a very young population, younger than the national average of 32.0 years.
The average fertility in Vrancea County is approx. 2.05 children/woman (1992), compared to the national average of 1.8.
The average mortality is very reduced (6.6 – 7.1%).

5. ENVIRONMENTAL IMPACT
5.1. Impact on Water
5.1.1. Impact on Waters during the Construction Period
We appreciate that the emissions of pollutants (resulted from site specific traffic, materials manipulation and lay-down, etc) that may get directly or indirectly into the surface or underground waters are not significant and do not modify the category of water quality.
The quantities of pollutants that usually get into the water curses during the execution period shall not affect the aquatic ecosystem and the water usage. Only by accidental discharge of large amounts of combustibles, oils or construction materials the aquatic environment could be damaged.
As concerns the possibility of phreatic water pollution, we appreciate it to be relatively reduced. It will be required to store the carburant in tightened reservoirs, to carry out the plants maintenance (washing, repairs, replacing the spare parts, oil changing, carburant supply, etc) only in special arranged areas (concrete platforms provided with settlers).
According to the Order No.1146/2002 for the Approval of Normative concerning the reference aspects for surface waters classification, the water courses intersected by the by-pass were inscribed in Quality Class II. The water from precipitations that is to discharge into these waters after washing the site platform shall not modify the waters quality category.
For the waste waters resulted from the site organizations must be respected the limits of pollutants existent in the waste waters evacuated into the water resources established according to NTPA – 001, in case they will be evacuated after purification into a water course adjacent to the site organizations.
If they will be evacuated in the existent sewerage network of a locality adjacent to the site, the maximum admissible concentrations are specified by NTPA – 002 “Normative concerning the Conditions of Evacuation for the Waste waters into the Localities Sewerage Networks”.
If after purification the waste sewage will be discharged on the adjacent fields, our suggestion is to impose the limits stipulated by STAS 9450 – 88 “Technical Conditions of Quality for Waters to be used for Agriculture Irrigations”.
16
5.1.2. Impact on Waters during the Period of Operation
The waters chronic pollution specific to traffic results from the wastewaters containing pollutant substances, waters resulted from precipitations that wash the road surface. The brut value of pollutants in these waters was presented in chapter 4.1.5.
To protect the quality of surface waters, the Romanian laws do not include the evaluation of pollutants dispersion. The Normative NTPA - 001/2002 specifies the maximum limits of pollutants into the wastewaters evacuated into the water resources.
The maximum concentrations of some pollutants specific to road traffic admitted for evacuation into the watercourses are the following (according to NTPA - 001/2002): - Total materials in suspension (MTS) 60 mg/dm3 3 - Bio-chemical Oxygen consumption (CBO5) 20 mg/dm - Chemical Oxygen consumption (CCO - Mn) 40 mg/dm3 - Oil products 1 mg/dm3 - Lead Pb 0,2 mg/dm3 - Zinc Zn 0,5 mg/dm3
We also mention that the sum of heavy metals ions must not exceed the concentration of 1 mg/dm3.
The irizations of oil products appeared into the outlets are interdicted.
Considering the prescriptions of Romanian Laws, the efficiency of water purification measures shall be appreciated by the concentrations of purified wastewaters evacuated into the watercourses crossed, without taking into account the debits of these courses.
The relatively restrictive character of Romanian Laws in this field is justified for the protection of watercourses situated in the road section in study.
In the conditions of an adequate purification of waste waters, that reduce the brut concentrations of pollutants by 75 – 95%, the evacuation of waste waters resulted from the by-pass into the adjacent water courses shall not affect significantly their quality. It is obligatory to obtain the purification efficiency prescribed by NTPA – 001/2002.
We appreciate that the underground waters are not to be affected by the chronic pollution specific to the traffic on the designed road.
Also, the fine alluvium strata of the surface assure an adequate protection for the phreatic underground waters. For the aquifer horizons of depth, the by-pass presence does not represent a risk factor for pollution.
17
Influence on Aquatic Ecosystems and Water Usages The purification measures designed for the wastewaters shall assure a minimum risk of pollution for the aquatic ecosystems and the usages. The pollutant substances evacuated into the watercourses shall not modify their quality class. Possible Positive Effects for Waters Quality As a result of measures designed (gutters, ditches, slope protections) to collect and evacuate the precipitation waters we appreciate the soil erosion and uncontrolled sediments in the road area to be reduced. Comparatively with the actual situation, the quantities and the concentrations of particles in suspension resulted from streaming waters shall be reduced, consequently improving the quality of surface waters referred by “materials in suspension”.
5.1.3. Water Protection Measures
5.1.3.1. Water Protection Measures during the Construction Period
At the actual phase, the Project does not provide the exact location of site organizations, or their number, that must be subsequently established by the Constructor.
It is recommended for the site organizations to be located far from the surface waters, forests and outside the localities. However, in order to limit or eliminate the impact, are designed special works, such as: purifying installations for wastewaters (septic tank) resulted from site organizations, settler for the concrete plant, etc.
The Constructor must obtain Approvals and Certificates for the operation of these objectives and the installations they serve, from the Organizations in charge.
The locations where the site organizations will be constructed must be established so as to avoid affecting the natural or human environment (by atmospheric emissions, by accidents resulted from the site traffic, by the materials manipulation, accidental unloading into the water courses of the plants transporting materials, noise, etc).
They must not be located next to sensitive areas (near water courses constituting water supply sources, near underground water captures) otherwise must be respected the conditions for their protection. Also, it is recommended to occupy areas as small as possible, to avoid taking out of the actual circuit of large fields.
For the site organizations and production bases must be designed a system for sewerage, purification and evacuation for sewage water resulted from the canteen, hygienic-sanitary spaces, as well as for meteoric waters that wash the site organization platform.
According to the number of persons to use the water here in sewage purpose, the system to be adopted shall have one or many septic tanks, periodically emptied,
18
or a purification station type mono-block to assure a high purification grade, so as the purified water to be discharged into an outlet or the neighboring fields.
The site organization platform must also be designed to assure the meteoric water collection by a system of paved ditches or gutters, where the particles might sediment before the water discharges, or there must be designed outflows conducting the water to the purification station for sewage waters.
During the works execution period, it is recommended to place settlers close to the watercourses.
5.1.3.2. Water Protection Measures during the Operation Period
The works designed to retain the pollutants during the exploitation must improve the quality of meteoric waters that wash the road platform before being evacuated into a natural receptor natural or the neighboring fields.
The works designed for capturing the meteoric waters (ditches, culverts) shall avoid the water standing on the road platform, keeping its surface in a good condition.
The water that washes the road platform contains diverse pollutants resulted from the road traffic (vehicles emissions, losses of oils and carburant, friction between tires and running way, etc) or being brought by the wind from the neighboring fields. We appreciate that a significant part of these substances shall be retained in the ditches.
To diminish the quantity of pollutants that may get into the surface waters or may infiltrate into the phreatic underground, also polluting the soil, must be designed oil settlers – separators, settling tanks and dispersion tanks.
To consider that a settler works efficiently if after the water purification the pollutants concentration shall diminish as follows: by 90% for the materials in suspension, by 75% for the chemical oxygen consumption (CCO) and for the bio- chemical oxygen consumption in 5 days (CBO5), and by 85% for heavy metals (lead, zinc).
The settling tanks and the oil settlers – separators shall be periodically cleaned, and the collected dross (material sediments and oils) shall be transported to an arranged cesspit.
These constructions shall be inspected periodically to verify if the slot or the overflow are not sealed, and the grill shall be also periodically cleaned from large floating particles that may remain between its interspaces (branches, wrappers, etc).
We note that in all the forecast alternatives for the road section the pollutants concentration in the purified water do not exceed the valued admitted by NTPA - 001 (normative that specifies the admissible limits of pollutants concentration in waste waters at the evacuation into the water sources).
19
During the maintenance activities currently occur other pollution sources, the most significant being the salt (NaCl) spread on the road during the frost periods. We appreciate that in hard winters approx. 5t/year/km of salt is spread to thaw the carriageway. This salt is washed by waters and infiltrated into the adjacent fields. The systematic studies elaborated in other countries attest that the ions of Na are less mobile and they fix into the soil on the first 10-40 cm. The ion Cl is more mobile and it may get into the underground waters. No dangerous pollution was noted on the environmental factors as a result of salt washed from the carriageway. Large quantities of NaCl may infiltrate into the soil in case of inadequate storage.
The maintenance activity shall use fertilizers and herbicide for the green areas on slopes and in the parking areas. The areas are small and the quantities of dangerous substances are also reduced. We appreciate the impact of this activity is insignificant in the designed road area, preponderantly agricultural and industrial.
5.2. Impact on Air
5.2.1. Air Impact During the Construction Period
The main air pollution sources have been classified as follows: • Construction Plants Activity • Transport (construction materials, prefabricates, personnel, etc) • Cement Concrete Preparation • Asphalt Mixture Preparation
In the site are also carried out other activities with potential air pollution, such as: carburant supply for plants and transport means, plants maintenance and repairs, heating the offices and the sewage water. The air pollution resulted from these activities is reduced during the construction period.
The emissions of air pollutants can be classified in emissions specific to carburant combustion in the engines (NOx, CO, COV, SO2, CH4, powders/PM, etc) and emissions specific to traffic and plants activities (powders in suspension and sediments).
Air Emissions in the Construction and Operation Period Construction Period Operation Period Specific Emissions Specific Emissions Pollutant Nature Total Total Emissions (kg/Km) Emissions (kg/Km) (kg/day) Daily Hourly (kg/day) Daily Hourly Nox 638,6 21,3 2,13 8718 97,0 5,7 CO 404,5 13,5 1,35 16.243 180,5 10,6 VOC 112,8 3,8 0,38 3.372 37,5 2,2

20
Examining the data presented in the Table above, we note that the hypotheses concerning the plants activity and the transport traffic, the hourly emissions of air pollutants, for 1km, during the construction period are 2 – 8 times smaller comparable to those for the operation period. The same dily emissions are 4 – 14 times smaller.
The carburant consumption, also for 1km of road or by-pass section, during the construction period is approx. 3 times smaller (hourly) and 5 times smaller (daily) than the consumption in the operation period.
Considering these hypotheses, the concentrations of pollutants in the area of plants activity and on the transport means route may be situated between the following values: 3 - NOx 0,05 – 0,1 mg/m - COVnm 0,3 – 0,4 mg/m3 - CO 0,8 – 1,4 mg/m3
These values can appear on short periods, for unfavorable weather conditions (wind perpendicular to the road, having the speed under 2 m/sec).
Laterally to the road path, the pollutants concentrations decrease with the distance to the road, after 20 – 30 m having approx. 50% and after 50 m having approx. 30% of the maximum values found at the road margin. After approx. 100 m, the air pollutant concentrations are insignificant (less than 10% of the values at the road margin).
The maximum potential concentrations, appreciated according to the values above, are at least 3 times smaller than CMA.
The main pollution in the site area is appreciated by pollutants concentration of 3 – 10 times smaller than CMA. The conclusion is that during the construction period the maximum admissible values for air pollutants concentrations shall not be exceeded in the area of site activities and on significant areas (hundred of sq.m for plants activity areas and tens of sq.m along the site roads). This conclusion refers to chemical pollutants (NOx, CO, COVnm, etc) and does not include the air pollution with powders in suspension and sediments.
According to the evaluation of air pollutant emissions during the construction period, the execution of earthworks (excavations, transports, compacting, etc), materials supply, cement concrete and asphalt mixtures fabrication, transport, etc, represent activities that generate significant quantities of dust/powders in suspension and sediments.
In the plants activity areas and on the transport means route the powders concentration in the air may frequently exceed 5 – 10 times the admissible concentration of 0.5 mg/cu.m (for protected areas).
The exceeding values may be greater in conditions of long time drought, earth roads, disregarding the minimum maintenance measures.
21
The effects of high concentrations of powders in the air are manifested, on people, by unpleasant sensations, discomfort, respiratory irritations, and even by sickness, after long-term exposure. The dust sediments on plants diminish the photosynthesis; reduce the growth and the productions.
The areas of air pollution with powders/dust are relatively limited in space, manifesting in the neighborhood of working points and transport means. According to the appreciations of US-EPA / AP – 42, the particles having the diameter more than 100µm sediment in short time, the sediment area being under 10m from the road margin. The particles of dimensions between 30µm – 100µm sediment in the first 100m laterals to the road. The particles of dimensions less than 30µm, respectively powders in suspension, sediment at distances of more than 100m.
During the construction period, the operations of cement and asphalt mixture plants represent activities of high potential for air pollution.
The pollution specific to asphalt plants manifests by emissions of toxic pollutants (NOx, CO, etc) resulted from combustibles combustion and emissions of powders/particles.
The evaluations of emissions in these plants areas have been presented above. The effect of these emissions on the air is local, only in the first 200 – 300 m after the plant installations location, in the case of asphalt plants.
Generally, the modern asphalt plants are provided with filters for retaining the pollutants, assuring low concentrations values that comply with the atmosphere protection norms, particularly with the Order No. 462/1993 “Technical Conditions concerning the Atmosphere. Norms for Limiting the Pollutant Emissions for Combustion Installations”.
Choosing a proper height for gas combustion furnaces ensures the conformation with the legislation regarding emissions.
It is the contractor’s responsibility to provide asphalt plant and sites for these plants (note that it is possible to be used only one plant).
All mentions about asphalt plants are also applicable to concrete plants, for the concrete plants being required measures to limit emission of powders, including cement particles.
The monitoring of emissions and imissions is obligatory.
5.2.2. Impact on Air during the Operation Period
The air impact evaluation of pollutant educed by analyzed sites made of mathematical modeling of pollutant dispersion, using a gauss type of model, the climatic model Martin and Tikvart.
22
The total concentration for a given mediation period is the sum of all sources’ concentrations for that period.
For short-term evaluation of air pollutant concentration on road area, the worst dispersion situation is atmospheric steadiness or weak wind perpendicular to the road direction. A 1m/sec wind speed, perpendicular on road, was taken into consideration for modeling.
The highest pollutant concentration is at road margin. At approx. 100m from the roadside, the pollutant concentration in the air is approx. 20% of the highest values.
Evaluation of air pollution on by-pass area is presented next, in comparison with the maximum accepted concentration set in STAS 12574 – 87 “Air in Protected Areas” and MAPM Order no. 529/2002.
We note that the maximum air pollution resulted from the traffic on the by-pass is given by the emissions of nitrogen oxides NOx, for which the maximum side road concentration, for short period (1 hour), in bad conditions of dispersion, may represent 28% of CMA. For the other analyzed pollutants, in the same conditions, the concentrations do not exceed 10%.
The annual concentrations of the traffic pollutants in the road area, resulted from traffic, do not exceed 15% of MAC for NOx and NMVOC and 5% of MAC for the other analyzed pollutants. In conclusion, it can be said that the air pollution in the by-pass area, for the working period after 2010, will inscribe into the accepted limits for that period. From all analyzed pollutants, the nitrogen oxides (NOx) can induce major short-term pollutions of approx. 70% of MAC at the junctions with other important roads, and of approx. 55% in the other situations.
The accepted limit for synergetic pollutants is not exceeded. Air pollution evaluation in operation period (after 2010) are based on the fact that present pollution is percent of MAC according to STAS 12574, and it will be maintained after 2010, in accordance to the prescriptions of Order 592/2002.
Road traffic pollution has significant values on the roadside, up to 50 – 100m distances. The concentrations of pollutants, up to 50 – 100 m from the roadside, represent 10 – 20 % of the maximum concentration at the platform margin.
The appreciations made in this chapter regarding air quality in the by-pass area must be considered sufficient. Emission flows were analyzed according to the EURO 1 requests. The percent of high performance cars shall be continuously raised due to vehicles import, significantly reducing the pollutant emissions.
EURO 1 – EURO 4 European norms are very restrictive towards emission factors.
Although traffic values will increase in the next 10-20 years, the traffic pollutant emission flow will decrease, as a result of engine improvement and increase of the vehicles number.

5.2.3. Measures to Decrease the Impact
5.2.3.1. Protection Measures for the Air during the Construction Period
● Air contamination sources related to the activities on the road location and borrow pit areas are free open sources, disseminated on large areas with different characteristics from industrial sources or such. Therefore, the collecting-cleaning- evacuation devices of the polluted air/residual gas are out of the question.
The collecting-evacuation devices and the powder retaining is a problem to be resolved on the site area, for asphalt and cement concrete plants.
● Collecting-evacuation devices are necessary for the following equipment: - Lime and cement silos: sack filters (with recovery by vibration-shaking) = 99,9% efficiency; - Asphalt plant: local polluted air retaining plant in the aggregates drying and mixing area, with sack filters = 99,9% efficiency; - Filer bunker: local polluted air retaining plant with cyclone = minimum 75% efficiency.
For decreasing the emissions from the asphalt and cement concrete preparation plants it is advisable to use modern technology plants, as less pollutant.
● Vehicles emissions must be according to the technical specifications set out during the periodical technical inspections, as required for all registered cars in the country.
● Works regarding site organization must be properly conceived and performed with modern endowment in barrack camp and plants, in order to decrease the emission of air pollutant in the air, water and soil. Setting all of them in one site is good for the minimizing the impact areas and encouraging a proper and controlled service.
● Cement and lime flow will be strictly supervised from the railways stations up to the silos by acquiring closed compressed air systems, filters for silos, bunkers, tank cars with specialized spreading.
● Portal type structures will be installed at the exit of the borrow pits, to spread water on the ground, forming a crust, stopping the soil spreading due to wind or traffic.
● The plants and the transport means shall be periodically checked for carbon monoxide level and exhaust gas level and shall be put in operation only after removing any dysfunctions. For that, the construction sites must be provided with the necessary testing instruments. It is recommended to use only plants and transport means with diesel engines, that do not evacuate Pb, and produce less carbon monoxide.
● The transport means shall be supplied with carburant only at site organization central gas station. The fuel truck can refuel the plants on the site, but only in
24
locations with no dust emissions. ● Dusty technological operations, such as soil fillings, shall be reduced during windy weather or the surface areas more intensely moistened. Special care shall be taken for laying down the first layer, as it involves dust lime spreading.
5.2.3.2. Protection Measures for Air during the Operation Period
For the main pollution source, on current working period, which is the traffic on the by-pass, the devices for collecting-purification-dispersion are out of discussion.
Road traffic pollution emission systems are in low proportion in Romania. With the evolution of local engines technologies and the national legislation in this domain these systems will evolve, with good effects on the environmental quality.
The plants and the transport means shall be periodically checked for carbon monoxide level and exhaust gas level and shall be put in operation only after removing any dysfunctions. For that, the construction sites must be provided with the necessary testing instruments.
5.3. Soil Impact
5.3.1. Impact on Soil during the Construction Period
The main impact on soil during the construction period is as the consequence of temporary land occupying for temporary roads, platforms, supplying and production bases, site organizations, waste deposits, etc. The ecological reconstruction of the area is compulsory.
The impact on soil resulted from all the activities performed during the execution period is important. All the areas taken over will induce soil structural changes.
The types of impact on soil, identified during execution period are: Vegetal soil removal and construction of an artificial profile resulted fro the execution of embankments on the road territory. Soil profile degradation on 3-5 m depth resulted from the borrow pits exploitation. Soil erosion Loss of fertile soil genuine characteristics by improper storage from road unbinding. Fertile soil removing/degradation in area of technological roads or deviations of actual access roads. Splitting soil areas from ecological circuits, by using concrete. Accidental overflows of substances directly on the soil.
