INSTRUCTIONS TO BIDDERS
1. Return of Tender Deposits The tender deposits of all unsuccessful bidders will be returned as soon as the bids have been checked for errors and a recommendation has been made to award the contract. The tender deposit of the successful bidder will be returned as soon as the contract is executed by the Owner.
2. Tender Deposits The tender deposit, shall serve as surety that, upon acceptance of the bid, a contract will be entered into for the proper performance of the work within fourteen (14) days of contract award.
The said tender deposit shall be forfeited and surrendered as the agreed amount of liquidated damages, in case of failure of the Contractor to enter into a contract as described above. The said tender deposit will be returned after the contract has been signed, and the required Bonds, Workers’ Compensation Board Clearance Certificate, and Insurance Certificate(s) have been furnished and approved by the Owner.
3. Withdrawal of Tenders A tenderer who has already submitted a tender may submit a further tender at any time up to the official closing time. The last tender received shall supersede and invalidate all tenders previously submitted by that Tenderer. A Tenderer may withdraw his tender at any time up to the official closing time by delivery of a letter bearing his signature and seal as in his tender, to the Owner. No other means of notification will be considered.
Where the Owner calls several tenders for opening on the same date and a tenderer submits tenders on all or more than one of the tenders, it is permissible, after the opening of tenders on one job, for a tenderer to withdraw tenders from further jobs, providing the tenderer is the low bidder on the tender call just opened and the further tenders have not been opened. Tenders withdrawn under this procedure cannot be reinstated.
4. Acceptance or Rejection of Tenders The Owner reserves the right to reject any or all bids as the interests of the Owner may require, without stating reasons therefore, and the lowest or any tender will not necessarily be accepted.
IB - 1 City of Niagara Falls Contract 2020-263-12 Chippawa Parkway Culvert Rehabilitation
Tenderers shall keep their tenders open for acceptance for forty five (45) days after the closing date. Withdrawal during this period will result in forfeiture of the tender deposit.
5. Unbalanced Tenders and Discrepancies Tenders that contain prices which appear to be so unbalanced as likely to adversely affect the interests of the Owner may be rejected.
When in a tender the amount tendered for an item does not agree with the extension of the estimated quantity and the tendered unit price, the unit price shall govern and the amount of the total Tender Price shall be corrected accordingly.
In the case of an error in addition, the correct sum of the amounts shown for each tendered item shall be deemed to be the total tender price regardless of the amount submitted by the tenderer.
6. Informal Tenders A tender shall be rejected as informal for any of the following reasons: a) Late bid. b) Incorrect tender form or envelope. c) Bids completed in pencil. d) Incomplete bids, including failure to include addendum. e) Bids with qualifications. f) Bid not signed and/or sealed. g) Erasures, overwriting or strikeouts not initialed. Tender award will be made on the basis of the specified items.

A written addendum will be sent to all tenderers if, in the opinion of the Contract Administrator, it is required.
8. Quantities are Estimated The quantities shown for the items in the Form of Tender are estimates only and are for the sole purpose of indicating to tenderers the general magnitude of the work. For any work done or materials supplied on the unit price basis, the Contractor will be paid for the actual measured quantities at the respective unit prices tendered.

It is strongly recommended that the Contractor use a trench box to install the watermain, sanitary sewer, storm sewer catchbasin leads, water services and any other pipes.

The height of the trench box shall be from 150mm below the bottom of the pipe to the level of the existing ground.
If the Contractor does not use a trench box as described above, then payment for the Granular >A= material will be based on the theoretical dimensions, which are as follows:
Width: Follow OPSD 802.010, OPSD 802.030 and OPSD 802.031 as applicable Height: From 150mm below the pipe to the level of the existing ground surface. Length: Equal to the pipe length
Therefore, to calculate Granular >A= weight (tonnes): Granular >A= (tonnes) = 2.4 x (Width x Height x Length - (π x D2 x L) / 4)

Landtek Limited is pleased to submit the geotechnical investigation report for the proposed rehabilitation structure (## about 650 of the existing gabion retaining walls at the culvert S053C) on Chippawa Parkway ELLIS m west of Stanley Avenue in the City of Niagara Falls, Ontario. The work was authorized by Engineering Inc. on behalf of the City of Niagara Falls on December 7, 2012.
A 2011 municipal bridge appraisal report indicates that the gabion baskets are rotating away from the support and settlements in the As roadway with the result that there has been reduced lateral roadway. well, the appraisal report indicated that although the concrete channel of the culvert appeared in good condition there was evidence of erosion and loss of subgrade support under the concrete channel.
Boreholes 1 and 2 were drilled on December 19, 2012, each to a depth of 5. 0 m, and at the west and east on site plan, in ends of the culvert respectively. The locations of the boreholes are shown the drawing 1 Appendix C. Photographs of typical site conditions are presented in Appendix D.
The ground surface elevations at the borehole locations were surveyed by City of Niagara Falls forces and were provided to Landtek Limited. The elevations refer to the geodetic datum.
SITE AND SOIL CONDITIONS
The subject site is at the location where an existing tributary watercourse to the Welland River crosses Chippawa Parkway, about 650 m west of Stanley Avenue in Niagara Falls. The ground levels at boreholes 1 and 2 were 175.4 m and 175. 0 m respectively and the water level of the watercourse at the time of the borehole drilling was approximately 4. 4 m below the centreline road grade at the middle of the bridge.
soil Warren and younger Geologic map data [ 1 and 2] indicate that the predominant overburden is Lake information pre -Iroquois stratified clay, silt, and sand that overlies shaley dolostone bedrock. The geologic 2] also indicates that the bedrock depth is in the order of 30 m to 35 m.
The borehole findings are consistent with the available data and indicate that native layered and fractured overlain with extends to depths of 1. 4 m at silty clay is the predominant native soil, The clay is fill that borehole 1 on the west side of the culvert and 1. 1 m at borehole 2 on the east side. The boreholes were terminated at 5. 0 m and bedrock was not encountered, SPT values in the silty clay range from 14 blows to 41 blows and indicate the stratum ranges from stiff to hard in consistency.
Boreholes 1 and 2 were drilled in the westbound and eastbound lanes respectively and there was about 75 mm of bituminous material over granular that had a thickness of 530 mm and 685 mm approximately at the two boreholes.
SOIL RETAINING WALL CONSIDERATIONS
subgrade support conditions for wall The existing native silty clay soil provides competent retaining construction such that there is no concern for long term differential settlements and base instability under movement which has the retaining wall. The existing gabion basket walls are distorted due to lateral resulted in ground settlement behind the walls and in the roadway. New soil retention systems and/ or and /or soil reinforcement to retaining walls should be constructed and should utilize tie -backs improve type lateral stability. Appropriate soil retaining systems for the project site are considered to be a gravity gabion basket wall with geosynthetic geogrid reinforcement layers, as illustrated in Figure 2, or a
geosynthetic reinforced earth type wall system as illustrated in Figure 3. The geosynthetic reinforced
earth system with geogrid and geosynthetic materials can include an erosion blanket with topsoil on the face to facilitate vegetation regeneration that results in the remedial soil retention work blending into the overall geometry and natural landscape of the area and a " seamless" wall of natural vegetation growth. Proposed Gabion Wall Rehabilitation, Welland River Culvert on Chippawa Parkway File: 12290 City of Niagara Falls, Regional Municipality of Niagara, Ontario Page ii January, 2013 EXECUTIVE SUMMARY
Proprietary design systems such as the Maccaferri systems provide similar capability with natural vegetation regeneration on the face of the gabion wall. Both the gabion basket soil retention system and the geosynthetic reinforced earth system have the advantage that construction can be carried out using conventional construction equipment and methods.
The recommendations provided in the previous section and illustrated in Figures 2 and 3 of the report text constitute design and construction concepts and require design analysis based on required finished surface grades, traffic loading impact, and slope inclinations. This work will form part of the preparation of design drawings and specifications with quantities for contract document and tendering purposes.
CHANNEL CONDITIONS
The concrete channel of the watercourse is supported on the native silty clay and although the concrete appears in sound condition and the flow is not impeded there is evidence that some scour and undermining of the concrete at the inlet and outlet ends ( refer to Photographs 3 and 4 in Appendix D) has occurred over the years. The silty clay is a fine grained soil with greater than 50 % of the soil particles passing the O. O75 mm sieve and the majority of the particles being clay size. Soil erodibility can be assessed using the Wischmeier Nomograph [ 3] and for the soils at the site the soil erodibility factor (K) is less than about 0. 5 which relates to a soil with a moderate resistance to erosion. This is consistent with the evidence that there has not been extensive progressive erosion under the concrete channel.
It is recommended that the voids under the concrete channel at the inlet and outlet ends of the culvert be filled with concrete ( 20 MPa nominal 28 day strength) prior to proceeding with any channel improvements see Figure 4 in the report text).
It is recommended that the creek bed upstream and downstream of the concrete lined culvert section should be treated with channel protection to dissipate flow and reduce the erosion and scour at the concrete lined channel section. The options for channel protection are rip -rap stone such as OPSS 1004 R -50 material, and rock filled Maccaferri gabion mats or an approved alternate. The gabion mats are designed as a rock -filled cellular basket structures and the cost effectiveness and application of the gabion mats should be reviewed with the supplier. All proposed creek bed alterations should be undertaken in full communication and with the approval of the Niagara Peninsula Conservation Authority.
PAVEMENT REINSTATEMENT CONSIDERATIONS
The installation of soil retaining systems will involve excavation back into the road and therefore road restoration will be required. Given that Chippawa Parkway is a bituminous surfaced road that accommodates a low volume of mixed car and truck traffic and there is no indication that the existing road is a high volume heavy commercial truck route, the pavement reinstatement can consist of hot mix asphalt on granular base or a bituminous surface treatment on granular base, The recommended asphalt pavement structure for reinstatement is given in Table 2 of the report text. The City of Niagara Falls may, however, have a standard pavement section that is preferred for the class of road.

1. 0 INTRODUCTION
Landtek Limited is pleased to submit the geotechnical investigation report for the proposed rehabilitation of the existing gabion retaining walls at the culvert structure ( # S053C) on Chippawa Parkway about 650 m west of Stanley Avenue in the City of Niagara Falls, Ontario. The work was authorized by ELLIS Engineering Inc. on behalf of the City of Niagara Falls on December 7, 2012 and was carried out in accordance with the Landtek proposal # P12166 dated November 21, 2012.
A 2011 municipal bridge appraisal report indicates that the gabion baskets are rotating away from the roadway with the result that there has been reduced lateral support and settlements in the roadway. As well, the appraisal report indicated that although the concrete channel of the culvert appeared in good condition there was evidence of erosion and loss of subgrade support under the concrete channel.
The primary objectives of the investigation were:
1) Determine the native subsurface soil and groundwater conditions at the site,
2) Provide recommendations with regards to the gabion wall rehabilitation and the channel
soil erosion;
3) Provide design and construction recommendations with respect to the restoration of
pavement approaches to the site;

2. 0 METHODOLOGY
Following utility clearances, boreholes 1 and 2 were drilled on December 19, 2012, each to a depth of 5. 0 m, and at the west and east ends of the culvert respectively. Split spoon samples and Standard Penetration Tests ( SPT's) were taken in the boreholes during the drilling at selected depths. The drilling was completed by an experienced soil drilling contractor and full time supervision of the drilling and sampling operations was carried out by personnel of Landtek Limited. The locations of the boreholes are shown on the site plan, drawing 1 in Appendix C. Photographs of typical site conditions are presented in Appendix D.
The ground surface elevations at the borehole locations were surveyed by City of Niagara Falls forces and were provided to Landtek Limited. The elevations refer to the geodetic datum.
The soil samples were transported to the Landtek Limited laboratory and visually examined to determine their textural classification. Moisture contents were carried out on all samples. Density determinations were completed on intact cohesive samples.

3. 0 SITE AND SOIL CONDITIONS
The subject site is at the location where an existing tributary watercourse to the Welland River crosses Chippawa Parkway, about 650 m west of Stanley Avenue in Niagara Falls. Figure 1 illustrates the location of the subject site. The ground levels at boreholes 1 and 2 were 175.4 m and 175. 0 m respectively and the water level of the watercourse at the time of the borehole drilling was approximately 4. 4 m below the centreline road grade at the middle of the bridge.
Geologic map data [ 1 and 2] indicate that the predominant overburden soil is Lake Warren and younger pre -Iroquois stratified clay, silt, and sand that overlies shaley dolostone bedrock. The geologic information [ 2] also indicates that the bedrock depth is in the order of 30 m to 35 m.

FIGURE 1 -- KEY PLAN OF SUBJECT SITE
The borehole findings are consistent with the available data and indicate that native layered and fractured silty clay is the predominant native soil. The clay is overlain with fill that extends to depths of 1. 4 m at borehole 1 on the west side of the culvert and 1. 1 m at borehole 2 on the east side. The boreholes were terminated at 5. 0 m and bedrock was not encountered.
EXISTING PAVEMENT
Eoreholes 1 and 2 were drilled in the westbound and eastbound lanes respectively and there was about 75 mm of bituminous material over granular that had a thickness of 530 mm and 685 mm approximately at the two boreholes.
FILL
Silty clay fill with some organic inclusions was encountered in each borehole to between 1. 1 m and 1. 4 m. The fill is mottled brown to grey -brown and moist. Proposed Gabion Wall Rehabilitation, Welland River Culvert on Chippawa Parkway File: 12290 City of Niagara Falls, Regional Municipality of Niagara, Ontario Page 4 January, 2013
SILTY CLAY
Native silty clay was encountered below the fill deposits and has a layered and fractured structure and contains scattered gravel sizes. SPT values in the silty clay range from 14 blows to 41 blows and indicate the stratum ranges from stiff to hard in consistency. The moist Bulk Specific Gravity ( BRD) is in the range of 2. 014 to 2. 161 and the moisture content values are in the order of 18 to 26 %.
The silty clay soil is considered to be a CL type soil on the Unified Soil Classification System which relates to inorganic silty clays of low to medium plasticity with liquid limits of less than 50 and greater than 50 % by mass of the soil particle sizes being smaller than 0. 075 mm.
GROUNDWATER
Groundwater seepage was not encountered in the boreholes during drilling and on completion the boreholes were open and dry.
The long term stabilized ground water table was not established however it is expected that the ground water level closely reflects the surface water conditions encountered in the watercourse.
The groundwater conditions and surface water flow conditions are expected to vary according to the time of the year and seasonal changes in precipitation. Water seepage is expected from soil fissures, layered peat deposits, and fill materials.

4.0 SOIL RETAINING WALL CONSIDERATIONS
The existing native silty clay soil provides competent subgrade support conditions for retaining wall construction such that there is no concern for long term differential settlements and base instability under the retaining wall. The existing gabion basket walls are distorted due to lateral movement which has resulted in ground settlement behind the walls and in the roadway. New soil retention systems and/ or retaining walls should be constructed and should utilize tie -backs and /or soil reinforcement to improve lateral stability. Appropriate soil retaining systems for the project site are considered to be a gravity type gabion basket wall with geosynthetic geogrid reinforcement layers, as illustrated in Figure 2, or a geosynthetic reinforced earth type wall system as illustrated in Figure 3. The geosynthetic reinforced earth system with geogrid and geosynthetic materials can include an erosion blanket with topsoil on the face to facilitate vegetation regeneration that results in the remedial soil retention work blending into the overall geometry and natural landscape of the area and a " seamless" wall of natural vegetation growth. Proprietary design systems such as the Maccaferri systems provide similar capability with natural vegetation regeneration on the face of the gabion wall. Both the gabion basket soil retention system and the geosynthetic reinforced earth system have the advantage that construction can be carried out using conventional construction equipment and methods.
The installation of a soil retaining system with tiebacks /geogrid reinforcement will require excavation back into the roadway and pavement restoration.

effectiveness and application of the gabion mats should be reviewed with the supplier. All
proposed creek bed alterations should be undertaken in full communication and with the approval of the Niagara Peninsula Conservation Authority.

6. 0 EXCAVATIONS
All temporary excavations and unbraced side slopes in the soils should conform to standards set out in the Occupational Health and Safety Act. The native silty clay is expected to be Type 2" soils according to the Occupational Health and Safety Act classification in Part III. Any fill or organic soils that may be encountered should be considered Type 3 to Type 4 soils which are characterized as previously excavated materials with a low degree of internal strength that can exhibit water seepage, saturation, and instability. In accordance with the Occupational Health and Safety Act, Paragraph 227 ( 3), the soil influencing the excavation must be classified as the type with the highest classification number. Excavation walls in soils that are characterized as Type 4 soils are required to be sloped back at 1 vertical to 3 horizontal from the bottom of the
excavation.
It should be possible to excavate the soils with a hydraulic backhoe. The stability of unbraced excavation walls is expected to be variable. The native very stiff silty clay soils should be stable 600 for short construction periods at slopes of about to the horizontal although wet and fractured soils may result in progressive sloughing to flatter slopes. For narrow excavation conditions in fill and organic soils, which cannot satisfy the Occupational Health and Safety Act requirements for unbraced side slopes, a trench box system should be used, or temporary shoring should be installed to maintain safe working conditions.
Groundwater seepage is expected to be variable and will depend upon the depth of the excavations, the time of year, and precipitation levels preceding construction that will also impact creek water levels. Water seepage in open cut excavations is expected below the watercourse water level. The seepage rate will depend upon the thickness and frequency of permeable layers and seams in the silty clay and whether there are sand layers connected to the water course. In general the silty clay is expected to have a low permeability. The details of the work and the scheduling of the work in the watercourse will require the approval of the Niagara Peninsula Conservation Authority.

7. 0 SOIL MANAGEMENT CONSIDERATIONS
An environmental site assessment ( ESA) was not undertaken by Landtek Limited as part of the site investigation. Consequently, chemical testing of soil samples was not undertaken to classify the environmental properties of the soils. The chemical characteristics of the existing silty clay soils are not known although there was no obvious environmental issues based on visual and olfactory examination of the soil samples. If the contractor must dispose of excavated soils off site, the party responsible for the property receiving the soils may require chemical testing to be completed that meets site -specific soil quality criteria. Proposed Gabion Wall Rehabilitation, Welland River Culvert on Chippawa Parkway File: 12290 City of Niagara Falls, Regional Municipality of Niagara, Ontario Page 11 January, 2013
8. 0 PAVEMENT REINSTATEMENT CONSIDERATIONS
The installation of soil retaining systems will involve excavation back into the road and therefore road restoration will be required. Given that Chippawa Parkway is a bituminous surfaced road that accommodates a low volume of mixed car and truck traffic and there is no indication that the existing road is a high volume heavy commercial truck route, the pavement reinstatement can consist of hot mix asphalt on granular base or a bituminous surface treatment on granular
base. The recommended asphalt pavement structure for reinstatement is given in Table 2. The City of Niagara Falls may, however, have a standard pavement section that is preferred for the class of road.

Granular Basecourse
The granular base course materials should meet OPSS Granular A specifications. Quarried 20
mm limestone, crushed to Granular °A" gradation specifications, is recommended.
Hot Mix Asphalt
The binder course asphalt should meet current OPSS specifications for HL 8 Binder Course. The surface course asphalt should meet OPSS specifications for HL 3 material. The asphalt
cement binder minimum grade should be PG 58 -28 for both the surface course and the binder
course asphalt.
Compaction
Hot mix asphalt should be compacted to the criteria set out in the OPSS paving specifications, which requires 93 percent of the Marshall Maximum Relative Density ( MRD).

APPENDIX A LIMITATIONS OF REPORT
The conclusions and recommendations given in this report are based on information determined at the borehole locations. Subsurface and ground water conditions between and beyond the boreholes may be different from those encountered at the borehole locations, and conditions may become apparent during construction that could not be detected or anticipated at the time of the geotechnical investigation. It is recommended practice that Landtek be retained during construction to confirm that the subsurface conditions throughout the site are consistent with the conditions encountered in the boreholes.
The comments made in this report on potential construction problems and possible remedial methods are intended only for the guidance of the designer. The number of boreholes may not be sufficient to determine all the factors that may influence construction methods and costs. For example, the thickness of surficial topsoil or fill layers may vary markedly and unpredictably. Contractors bidding on the project, or undertaking construction on the site should make their own interpretation of the factual borehole information, and establish their own conclusions as to how the subsurface conditions may affect their work.
The survey elevations in the report were obtained by Landtek Limited or others, and are strictly for use by Landtek in the preparation of the geotechnical report. The elevations should not be used by any other parties for any other purpose.
This report was prepared for the City of Niagara Falls and their designated design consultant. Use of this report by another party, or any reliance on or decisions to be made based on it, are the responsibility of such parties. Landtek Limited accepts no responsibility for damages, if any, suffered by any other party as a result of decisions made or actions taken based on this report.
This report does not reflect environmental issues or concerns related to the property unless otherwise stated in the report. The design recommendations given in the report are applicable only to the project described in the text and then only if constructed substantially in accordance with the details stated in this report. Since all details of the design may not be known, it is recommended that Landtek Limited be retained during the final design stage to verify that the design is consistent with the report recommendations, and that the assumptions made in the report are still valid.

APPENDIX B Information for Contractors Performing Work on the Niagara Falls Drinking Water System APPENDIX B Performing Work on the Niagara Falls Drinking Water System
INFORMATION TO CONTRACTOR
Performing Work on the Niagara Falls Drinking Water System
In 2002, the Safe Drinking Water Act came into force, and changed how drinking water is tested, monitored and regulated in the Province.
Part of the SDWA requirements, is that all municipalities in the province must obtain a Municipal Drinking Water Licence for their drinking water system. In order to obtain a licence, all municipalities in the province are required to implement a quality management system (QMS) for their drinking water departments, in accordance with the Drinking Water Quality Management Standard. The City of Niagara Falls was required to apply for their licence and submit evidence of having implemented a QMS (by submitting an Operational Plan) by May 1, 2009 – and on September 9, 2009, the City received its Municipal Drinking Water Licence.
Section 5.1 of the City‟s licence it states that: The owner and operating authority shall ensure that any person authorized to carry out work on or to operate any aspect of the drinking water system has been informed of the SDWA, all applicable regulations made in accordance with that act, the drinking water works permit and this licence, and shall take all reasonable measures to ensure any such person complies with same.
Therefore, to ensure the City can demonstrate that contractors who perform work on the distribution system have been informed; contractor personnel must review the following information.
Who can operate the drinking water system? Section 12(1) of the SDWA specifies that only persons holding a valid Operator‟s Certificate can „operate‟ a municipal system.
The following activities are considered „Operating Functions‟ and therefore require a Certified Operator: Open and close valves and gates Isolate watermains and reconnect isolated watermains Flush hydrants Conduct water tests for the 24 operational parameters listed under O.Reg. 248/03 (i.e. testing for chlorine residual, turbidity, pH) Control flow or pressure of drinking water in drinking water subsystems Disinfect or treat water using chemicals Monitor gauges, meters and control valves related to distribution of drinking water Add chlorine or other chemicals to the distribution system Perform wet-taps
1 of 3 APPENDIX B Performing Work on the Niagara Falls Drinking Water System
Note: The above list is NOT considered to be exhaustive. Tasks that impact drinking water quality may also require a valid Operator‟s Certificate. Contact the Ministry of Environment for additional information.
Therefore, contractor personnel are not allowed to perform any of the „Operating Functions‟ listed above. If in doubt, check with the Municipal Inspector or Environmental Services Water Operator before performing a task.
Are there any special conditions/instructions etc. to be considered during water appurtenance installation? It is important to note that under Section 20(1) of the SDWA: No person shall cause or permit any thing to enter a drinking water system if it could result in: a) a drinking water health hazard b) a contravention of a prescribed standard; or c) interference with the normal operation of the system
Therefore Contractors should take all reasonable precautions to ensure that nothing enters the watermain during construction that could cause any of the above issues to occur (i.e. taking care to ensure the watermain remains as clean and debris-free as possible during construction, using only approved products during construction (i.e. if have to grease joints – must use a food-grade product)). This clause also means that authorized City staff will be examining the watermain construction on a regular basis to ensure compliance.
During Water Appurtenance Commissioning
According to the City‟s Drinking Water Works Permit, Section 2.3: All parts of the drinking water system in contact with drinking water which are: 2.3.1 Added, modified, replaced, extended; or 2.3.2 Taken out of service for inspection, repair or other activities that may lead to contamination shall be disinfected before being put into service in accordance with the provisions of the AWWA C651 – Standard for Disinfecting Water Mains.
Moreover, Section 10 of the City‟s licence states, in part, that: 10.1 Nothing in this licence or the drinking water works permit shall be read as to permit: 10.1.1 The discharge of a contaminant into the natural environment that causes or is likely to cause an adverse effect 10.1.2 The discharge of any material of any kind into or in any waters or on any shore or bank thereof or into or in any place that may impair the quality of the water of any waters.
2 of 3 APPENDIX B Performing Work on the Niagara Falls Drinking Water System
10.2 All reasonable steps shall be taken to minimize and ameliorate any adverse effect on the natural environment or impairment of the quality of water of any waters resulting from the operation of the drinking water system including such accelerated or additional monitoring as may be necessary to determine the nature and extent of the effect or impairment.
This means that, during the flushing of the watermain during and/or after disinfection – the waste water cannot be discharged into a storm sewer or onto land where it may enter a storm sewer or ditch, without be treated to eliminate the chlorine and reduce the toxicity. Even treated water from the existing distribution system cannot be “wasted” without treatment to eliminate the chlorine.
Summary The Municipal Drinking Water Licensing program is new. Therefore, our expectations may seem “higher” than other municipalities, or even from other projects previously completed in Niagara Falls. However, as more and more municipalities receive their licences), the general conditions will be identical from municipality to municipality – this process has created consistent “rules” for all municipalities, which should make it easier for contractors to work at different municipalities as the general “rules” will be the same.
You are expected to ensure your staff on-site are aware of these requirements, as well as any sub-contractors that will have contact with the drinking water system. City Staff is willing to attend on site to answer questions or go over the above information with your staff.
This is a new process for all, any comments you can provide that can improve this process is greatly appreciated.
