W12A Service Area Amendment Environmental Screening Process

1.0 IntroductionThe W12A Landfill is approved by the Ministry of Environment and Climate Change (MOECC) toaccept solid, non-hazardous waste generated within the boundaries of the City of London fordisposal and Municipal Hazardous and Special Waste (MHSW) generated from London andMiddlesex County at the HSW Depot located at the W12A Landfill for transfer to appropriaterecycling/processing sites. The W12A Landfill is also approved to accept residential waste fromThames Centre in the winter months when their landfill is closed provided a corresponding amountof waste from London is shipped to Thames Centre in the summer months when their landfill isopen. The location of the W12A Landfill and its approved service area (area from which it canaccept materials) is shown on Figure 1.

The City of London is proposing to accept waste from five locations that are outside W12A Landfill’scurrent approved service area. These locations and the types of waste to be accepted are:

1) Lake Huron water treatment plant (water treatment plant process residuals),2) Elgin Area water treatment plant (water treatment plant process residuals),3) TRY Recycling’s Clarke Road facility (construction and demolition (C&D) recycling process

residuals and residential garbage),4) Thames Centre (curbside collected municipal waste and no shipping a corresponding amount

of City waste to the Thames Centre Landfill) and5) Elgin County MHSW.

It is proposed to accept materials from these new locations because:

• Lowers cost— Cost for London to operate the landfill is lowered because of ‘economies ofscale”. Tipping fees for the municipalities and organizations using the W12A Landfill are lowerthan alternative disposal locations.

• London waste — Over 80% of the waste from the new areas is generated as a result ofproviding services to residents of London (e.g., clean drinking water, recycling location for C&Dwaste).

• Regional coordination — London and several nearby municipalities already work together onrecycling programs. Accepting MHSW from Elgin County and municipally collected garbagefrom Thames Centre is a continuation of the regional approach to finding solutions formanaging waste. For example, accepting MHSW from Elgin County will provide a convenientlocation for its residents to take their MHSW which should reduce the amount of materialending up in the garbage.

Increasing the service area of the W12A Landfill will require the City to fulfill the requirements ofthe Environmental Assessment Act (EAA) by completing an Environmental Screening and toamend its Environmental Compliance Approval (ECA) issued under the Environmental ProtectionAct (EPA). These requirements are described in Section 3.0.

Details on the W12A Landfill are provided in Section 4.0. No other changes to the landfill areproposed other than increasing the service area to accept waste from the five locations listedabove. There will be no changes to the 1) landfill’s approved rate of fill (amount of waste thelandfill can receive in a year, 2) types of waste that can be accepted, 3) size or capacity of thelandfill or 4) engineering controls to protect the environment and mitigate nuisance impacts.

W12A Service Area Amendment Environmental Screening Process

3.0 Approval Processes

3.1 Environmental Assessment Act (EAA)The EAA regulation for waste management projects allows for projects/undertakings that meetspecified criteria to be assessed via a scaled down version of the normal EnvironmentalAssessment process called an Environmental Screening Process. The Environmental ScreeningProcess is used for routine projects that have predictable and manageable environmental effects.Increasing the service area of a landfill is one of the projects that are allowed to proceed throughthe Environmental Screening Process.

The Environmental Screening Process is a self-assessment process that is to involve the followinggeneral steps:

• publication of Notice of Commencement of the Environmental Screening project/undertaking,including a description of the project;

• application of specified criteria to identify potential environmental effects of theproject/undertaking, which will include a summary of any identified environmental effects;

• consultation with interested persons, Aboriginal peoples and government agencies;• development of impact management measures should they be required as a result of

environmental effect assessment and public consultation;• further consultation with interested groups; and• preparation and publication of an Environmental Screening Report summarizing the results of

the project review, consultation, mitigation and impact management measures.

This process is illustrated in detail in Figure 3. The reader is referred to the document Guide toEnvironmental Assessment Requirements for Waste Management Projects(http://www.ontario.ca/document/guide-environmental-assessment-reguirements-wastemanagement-projects) for further details on the Environmental Screening Process.

3.2 Environmental Protection Act (EPA)In Ontario, landfilling sites and other waste management activities are subject to Part V of the EPAand the regulations made under the Act. The basic legislative framework for waste management isdefined in Part V and the regulatory requirements for the design and operation of waste disposalsites are included in Regulation 347 General — Waste Management.

Section 27 of the Act requires that an ECA be obtained from the Ministry of the Environment andClimate Change (MOECC) for the establishment, operation, alteration or enlargement of alandfilling site. The ECA governs the overall design and operations of the site including how largethe site is to be, the types of waste to be accepted and where waste can come from. To changeany of these conditions requires an amendment to the site’s ECA. The amendment processrequires public consultation (can be done in conjunction with EnvironmentalAssessment/Environmental Screening Process) and the submission of technical information to theMOECC for approval.

The reader is referred to the document Guide to Applying for an Environmental ComplianceApproval (https://dr6j45jk9xcmk.cloudfront. net/documents/962/5-8-2-eca-guide-en . pdf) for furtherdetails on the ECA process.

4.0 WI2A Landfill

4.1 BackgroundThe W12A Landfill is located at 3502 Manning Drive in the City of London approximately 1.5kilometres west of Wellington Road (see Figure 1). The landfill is bounded by roads to the southand west and agricultural land to the north and east. All but one of the adjacent properties to thenorth and east of the landfill are owned by the City of London.

The W12A Landfill is approved by the MOECC (ECA # A042012) to accept solid, non-hazardouswaste generated within the boundaries of the City of London for disposal and MHSW generatedfrom London and Middlesex County at the HSW Depot located at the W12A Landfill for transfer toappropriate recycling/processing sites. The W12A Landfill is also approved to accept residentialwaste from Thames Centre in the winter months provided a corresponding amount of waste fromLondon is shipped to Thames Centre in the summer months when their landfill is open.

Information on the landfill’s approved rate of fill, types of waste that can be accepted, size/capacityof the landfill and engineering controls to protect the environment and mitigate nuisance impacts aresummarized in the following sections of this report. The reader is referred to the document W72ALandfill Site 2074 Annual Status Report for further details on Wi 2A Landfill. A copy of thisdocument is available from the Solid Waste Management Division, City of London (emailifavalarlondon.ca or call 519.661.2500 ext. 2794).

4.2 Rateof FillThe current ECA permits the annual disposal (referred to as the “rate of fill”) of 640,000 tonnes ofwaste. The historical quantities and types of waste received at the site is presented in Table A-iin Appendix A and summarized in Table 2 below.

Table 2 - Waste Quantities Received at the WI2A Landfill

Tonnes Description of Activity

220,000 Waste received in 2014

235,000 Average annual amount of waste received for disposal for 5 year period 2010- 2014

240,000 Average annual amount of waste received for disposal for 5 year period 2005 - 2009

275,000 Highest 5 year average annual amount of waste received for disposal 1984 - 1988

310,000 1987- the largest annual amount of waste_(garbage) received

380,000 1989 - the largest annual amount of waste (garbage and clean fill) received

200,000 Projected waste in 2015

240,000 Projected waste if proposed service area expansion is approved

The average quantity of waste being disposed of at the landfill averaged 235,000 tonnes per yearover the five year period ending in 2014.

Recently, two large commercial waste management customers have reduced and nowdiscontinued using the W12A Landfill to dispose of waste from their London based customers, infavour of disposing of that waste at their own landfills located in southwestern Ontario. It isunknown when or if the two customers may return to using the W12A Landfill. This, coupled with areduction in the amount of contaminated soil coming to the landfill, is expected to result in a 20%drop in tonnes arriving at the Wi 2A Landfill. It is estimated the annual amount of waste receivedfor disposal to average approximately 200,000 tonnes per year (without the proposed changesidentified in this report).

Page 7

W12A Service Area Amendment Environmental Screening Process

No change to the landfill’s approved tate of fill is required in order to accept waste from theproposed expansion of the landfill’s service area.

4.3 Types of WasteThe W12A Landfill is licensed to receive solid non-hazardous municipal waste for disposal andMHSW waste for transfer. The definition of municipal waste in Regulation 347 General— WasteManagement includes water treatment plant process residuals, C&D recycling process residualsand residential garbage.

No change to the landfill’s approved list of materials is requited in order to accept waste from theproposed expansion of the landfill’s service area.

4.4 CapacityThe W12A Landfill is approved for landfilling on 107 hectares within its 142 hectare site area andhas a total approved disposal volume of 13,800,000 m3 (including final covet).

Based on a topographic survey, it is estimated that the remaining disposal volume is approximately3,500,000 m3 as of January 2015. After allowing for final cover (380,000 m3) anddaily/intermediate cover (assume 4 parts waste to 1 part soil), 2,500,000 m3 of disposal capacity isavailable for waste. This will provide between 8 and 14 years of capacity depending on howresidential, IC&l and C&D processing residual waste is managed in the future. With no changes inthe existing waste management practices it is estimated that the W12A Landfill will have 10 to 11years of capacity. The reader is referred to Appendix A for the site life calculations.

No changes to the landfill’s approved landfilling area or capacity are required in order to acceptwaste from the proposed expansion of the landfill’s service area.

4.5 Engineering ControlsThe landfill has a number of engineering features/controls to protect the environment and reducenuisance impacts. These engineering features/controls include leachate collection systems,stormwater management ponds, landfill gas collection and flaring system, groundwater monitoringwells, etc.

No changes to the landfill’s engineering features/controls are proposed in order to accept wastefrom the proposed expansion of the landfill’s service area.

4.6 Land Use ConsiderationsThe majority of land within 500 metres of the landfill is in agricultural production. Other land usesinclude an aggregate pit, vacant land, radio transmission towers, single family dwellings,vegetative areas and a Material Recovery Facility owned by the City.There are a total of 11 single family residences within 500 metres of the landfill. Four of theresidences are owned by the City and rented out.No changes to the landfill’s land uses, zoning or Official Plan designation are proposed in order toaccept waste from the proposed expansion of the landfill’s service area.

4.7 TrafficIn 2009 the City retained IBI Group to conduct a transportation impact assessment for proposednew land uses on Manning Drive adjacent to the W12A Landfill. The proposed new land useswere a Materials Recovery Facility (MRF) and a leachate pre-treatment plant (both planned Cityfacilities). The main body of the report is provided in Appendix B and summarized below.

The traffic study examined the adequacy of the existing roadway network by determining if theroadway network could accommodate future traffic volumes. The impact assessment assumed nogrowth in traffic volumes expect for the City facilities on Manning Drive. The projected 2015 trafficvolumes for these facilities from the report are presented in Table 3.

Notes1. Data from Exhibit 3-2 Proposed New Land Uses Adjacent to W12A Landfill, Transportation Impact

Assessment (IBI Group, 2009). Exhibit has vehicle counts for 2008. IBI Group increased vehiclescounts for trucks by 10.5% per year and for small vehicles by 4% per year.

2. Data from Exhibit 3-3 Proposed New Land Uses Adjacent to WI2A Landfill, Transportation ImpactAssessment (IBI Group, 2009). Vehicle estimates assume the Material Recovery Facility is processing50,500 tonnes per year (conservative estimate).

3. Data from Exhibit 3-4 Proposed New Land Uses Adjacent to WI2A Landfill, Transportation ImpactAssessment (lBl Group, 2009).

The 2009 traffic study concluded...

In summary, the findings of this study indicate that the roadway network, in itspresent state, can accommodate projected increases in site traffic without theneed for operational improvements

A summary of the 2014 waste tonnages and number of vehicles using the Wi 2A Landfill and theMRF are presented in Table 4 (next page). The City did not proceed with the construction of aleachate pre-treatment facility. Table 4 shows that the annual traffic to City facilities on ManningDrive was 80,000 per year or 53% of the annual traffic volume used in the IBI report. The lowerthan projected traffic volume is a result of a reduction in waste going to the landfill instead of theprojected increase, slower growth of recyclables coming to the MRF and not proceeding with theconstruction of the Leachate Pre-Treatment Plant.

Designated Haul RouteThe existing and future designated haul route for the W12A Landfill is shown on Figure 4.Currently all vehicles are required to access the W12A Landfill by travelling on Wellington RoadSouth to Manning Drive. When the Wonderland Road South/Highway 401 interchange iscomplete, vehicles will also be allowed to travel on Manning Drive from the new interchange toreach the landfill.

Construction of the new Highway 401/Wonderland Road interchange began in 2014 and isexpected to be complete in late 2015. Manning Drive between the landfill entrance andWonderland Road immediately south of the new interchange is also being reconstructed in 2015.

This section of Manning Drive is identified as a 24-hour truck route but is currently subject to springload restrictions. This project will upgrade the road to standard widths, improve the pavement

5.0 Waste TypesAs discussed in Section 1.0, it is proposed to increase the service area of the W12A Landfill toinclude waste from five additional sources. The waste types that will be coming to the W12ALandfill from these five sources are water treatment plant process residuals, construction anddemolition recycling process residuals, municipal waste and municipal hazardous or special waste(MHSW). Each of these waste types is described below.

Process residuals from the Lake Huron plant are currently being sent to a closed landfill in theMunicipality of South Huron and being used as fill. It is expected that this option will no longer beavailable in the near future and it is proposed to send the residuals to the W12A Landfill.

The process residuals from the Elgin Area plant are currently being discharged back into Lake Eriehowever a residuals management facility is under construction and once completed will capturethe residuals. It is proposed to send the capture residuals to the W12A Landfill. The residualsmanagement facility is expected to be operational by early 2016.

Estimates of the average daily, peak daily and average annual quantities generated at the LakeHuron and Elgin area plants are presented in Table 5. Overall, it is estimated that on averageapproximately 20,000 tonnes per year of process residuals will be generated from the two watertreatment plants (assuming an average of 54 tonnes is generated 365 days a year).

5.1 Water Treatment Plant Process ResidualsIt is proposed to accept process residuals from the Elgin Area and Lake Huron water treatmentplants. This waste is generated when turbid water from the lakes is pumped into the watertreatment plants and the suspended solids causing the turbidity are removed. The residuals aregenerated from filter backwash waste water and other intermittent plant process waste streams.This process residual is soil like in nature (i.e., suspended sediment from turbid lake water). Apicture of the water treatment plant process residuals and the water treatment plant processresiduals being loaded onto a truck for transport is shown in Figure 5 below.

1. Data for Lake Huron treatment plant from Residual Management Facility (CH2M HillLimited, 2010). Volume estimated assuming residual is 25 percent solids.

2. Data for Elgin Area treatment plant from Elgin Area Water System, ResidualsManagement Facility, Pre-Design Report (AECOM, 2010). Volume estimated assumingresidual is 20 percent solids.

3. Residuals are generated 365 days/year.4. Design Table from above mentioned reports are presented in Appendix C.

The process residuals consist of approximately 20% to 25% screened sediment and 75% to 80%water by weight. Grain size analysis (Appendix D) of the process residuals from the Lake HuronWater Treatment Plant shows the screened sediment is 70% medium to fine grain sand and 30%silt and clay. The material has a slight decomposing aquatic vegetation smell. This material willbe acceptable as daily cover material and therefore should have limited or no impact on the site lifeof the W12A Landfill. Process residuals from the Elgin Area Water Treatment Plant are expectedto have similar grain sizes.

The Lake Huron plant will average seven to eight trucks per week with a maximum of three in oneday. Each load is approximately 20 m3 (20 tonnes). It is estimated that upon completion of theirresiduals management facility, the Elgin Area plant will average 10 to 12 trucks per week with amaximum of 10 trucks in one day. In estimating the maximum number of trucks in one day, it isnoted that some of the residuals generated can be stored and shipped the following day.

Chemical testing of the process residuals from the Lake Huron plant shows that the material meetssoil quality standards for agricultural land use except elevated concentrations of the F2 fractionand F3 fraction for petroleum hydrocarbons. (For testing purposes, petroleum hydrocarbons arenormally divided into four groups (fractions) depending on the length of their carbon chain.Generally, the shorter the length of the carbon chain, the more volatile the compound is.)

These test results are summarized Appendix E. The Certificates of Analyses are also presented inAppendix E.

The Lake Huron Primary Water Supply System (LHPWSS) is currently investigating the source ofthe petroleum hydrocarbons within the Residuals Management Facility (RMF). One potentialsource is the thickeners used to thicken and reduce the volume of the residuals before dewatering.There is the potential for the petroleum hydrocarbons to be caused by a grease ring build up. Inlate 2014 the LHPWSS had the equipment manufacturer in to assess this and they made somechanges related to the grease seal to the north and south thickeners. The persistent low levels ofpetroleum hydrocarbons may now be due to recirculation of the water at various points within the

Page 13

AI1A A.- Fnvironmpntil Scrppnin Prnrsc

RMF. The LHPWSS is currently considering removal of any remaining petroleum hydrocarbonsthrough the use of oil absorbent socks/booms with future consideration for additional methods ifrequired.

5.2 Construction and Demolition Recycling Process ResidualsIt is proposed to accept construction and demolition (C&D) recycling process residuals from TRYRecycling’s Clarke Road facility (ECA# A040146) located at 21463 Clarke Road, RR#1 Arva.This facility is located just outside of the north eastern boundary of London with a majority(between 80% and 90%) of the materials processed at this facility being generated from London.

These materials generally arrive at the TRY Recycling facility from London in one of four methods:1. Delivered directly by TRY Recycling customers conducting business in London;2. Private haulers that serve customers in London and take materials to TRY Recycling;3. Direct delivery by Londonets; or4. Materials that are collected at the City’s EnviroDepots and picked up by TRY Recycling.

Approximately 80% of the C&D material processed at the TRY Recycling facility is recycled while20% becomes process residuals. The process residual generated is solid non-hazardous wasteconsisting of film plastic, insulation, flat roofing, bulky items like mattresses and couches and othermaterials that cannot be recycled. An example of C&D residuals is shown in Figure 6.

The quantity of C&D process residuals is expected to average approximately 20,000 tonnes peryear and may vary from 15,000 to 30,000 tonnes per year (see Table 6).

The number of trucks is expected to average 15 per week and will vary from an average of two tofour trucks per day (Monday to Friday). It is expected the maximum number of trucks on anysingle day will be 10.

5.3 Municipal GarbageIt is proposed to accept municipal garbage from a small vehicle drop-off depot (referred to as anEnviroDepot) located at the TRY Recycling composting facility (ECA# 7474-5E3QC8) at 21462Clarke Rd, RR#1 Arva and municipally collected residential curbside garbage from the municipalityof Thames Centre.

The City of London contracted TRY Recycling to open the EnviroDepot in the fall 2014 to serveresidents in the North of London. Currently the facility can only accept yard materials includingleaves but an application has been filed with the MOECC to amend the facility’s ECA to allow theEnviroDepot to accept a wide range of materials including residential garbage. The majority ofwaste brought to this depot will be from London residents. This waste is currently going to theW12A Landfill but the TRY depot will provide a more convenient location once it opens. TheEnviro Depot will also accept materials from non-City of London customers using the TRYRecycling facility but the majority (between 80% and 90%) of materials generated are expected tooriginate from London. It is estimated that the maximum annual amount of residential garbage thatwill be generated is 500 tonnes. This translates into approximately one truck per week.

The City has an agreement with Thames Centre toaccept municipally collected residential garbageduring winter months (so that the Thames CentreLandfill can close in winter months) and in return theCity can dispose of an equivalent amount ofresidential garbage in the Thames Centre Landfill inthe summer. Thames Centre collects approximately800 tonnes during the winter season (see Table 7).There will be approximately 100 to 110 trucks peryear with the maximum number of trucks on any day being 3.

5.4 Municipal Hazardous and Special Waste (MHSW)The W12A Landfill Site also contains a MHSW depot where all MHSW waste accepted istransferred to appropriate recycling/processing facilities for management. The facilities currentlybeing used are listed in Appendix F. It is proposed to accept MHSW from the County of Elgin.There is currently no permanent MHSW depot in the County of Elgin. Residents can take somematerials (e.g., paint, batteries, fluorescent tubes/bulbs) to local retailers while proper disposal ofother materials (e.g., solvents, pesticides, fertilizers) is limited to the occasional special collectionevents held by the local municipality. Having access to a permanent MHSW depot will provideconvenience to the residents of Elgin County and encourage the proper management of thesematerials instead of placing them in the garbage. Having more customers to London’s MHSWdepot (referred to as a Household Special Waste Depot) will lower its operating costs due to“economies of scale”.

The City and six of the seven local municipalities that make up Elgin County already work togetheron recycling. Recyclables from these municipalities come to London’s Manning Drive RegionalMaterial Recovery Facility located beside the WJ2A Landfill. The City and these municipalitieshave aligned their recycling programs to accept the same materials and undertake joint educationand awareness campaigns. Having Elgin’s residents use the City’s Household Special Waste(HSW) Depot is a natural progression of the municipalities collaborative approach to find regionalsolutions that are more effective than having individual municipalities finding their own solution.

The MHSW brought to the HSW Depot by Elgin County residents is expected to be similar innature as that brought by London and Middlesex County residents. An estimated breakdown ofthe material is shown in Figure 7.

The City of London has approximately 170,000 households and in 2014 generated about 400tonnes of material (about 2.4 kilograms/household) from 9,000 visits (about 1 visit per 20households). Assuming the same generation rate for Elgin, the W12A Landfill HSW depot wouldreceive approximately 900 visitors per year bringing 40 tonnes of MHSW.

The peak number of visitors from Elgin County, approximately 20 per day, is expected to occur onSaturdays.

5.5 Potential Additional Waste Quantities and TrafficTable 8 provides a summary of the additional waste quantities to be managed at the W12A Landfilland the number of vehicles expected.

5.6 Potential Impact of Landfill CapacityWith no changes in the existing waste management practices it is estimated that the W12A Landfillwill have 10 to 11 years of capacity.

Table 8 shows an average of an additional 41,000 to 42,000 tonnes/year would be disposed of atthe landfill. Only 21,000 to 22,000 tonnes of this waste would consume capacity as it is expectedthe water treatment plant process residuals (20,000 tonnes/year) can be used as daily cover andtherefore not consume any capacity designated for managing waste.

Over 10 years there would be approximately 210,000 to 220,000 tonnes of additional C&D processresiduals and residential waste that would require disposal. This is estimated to consumeapproximately 350,000 m3 to 400,000 m3 of capacity based on an average density of 0.7 tonnesper m3 and a 4 to 1 waste to cover soil ratio. This would reduce the site life of the W12A Landfill byapproximately one year. This leaves 9 to 10 years capacity assuming no other changes to currentwaste quantities being disposed at the W12A Landfill.

The reader is referred to Appendix A for detailed site life calculations.

6.0 Anticipated Environmental Effects

As part of the Screening Process a proponent must apply a standard set of screening criteria inorder to identify if the project has any potential environmental effects. The screening criteria arepresented in the form of a checklist with the option of a “Yes” or “No” response. The proponent isto answer “Yes” even if the proponent believes that a potential environmental effect could likely bemitigated. The completed screening for this project is presented in Table 9.

The only criteria identified with the potential for environmental effects was “Might this project causenegative effects related to traffic?”. This potential effect was identified because annual and dailytraffic to the landfill will increase and traffic patterns change if the landfill accepts wastes from theproposed new sources.

In general, other potential environmental effects were determined to have a minimal or no effectbecause:

• there is no change to the approved types of waste being received;• there is no change to the approved size or capacity of the landfill;• there is no change to the approved engineering controls at the landfill;• the total waste being disposed of at the W12A Landfill, including the potential additional

quantity of waste from the five new locations, will be less than the landfill’s approvedrate of fill; and,

• the expected quantity of waste coming to the landfill in 2016, including the potentialadditional quantity of waste from the five new locations, will be less than what has beencoming to the landfill in recent years because of the recent loss of two large wastehaulage customers.

A breakdown of the actual 2014 traffic, 2015 traffic projections from the IBI report and theexpected 2016 traffic if the changes to the service area of the landfill proceed are presented inTable 10.

This Table shows that the projected annual volume of traffic in 2016 is less than projections inthe IBI report. The IBI looked at scenarios where all the landfill and MRF traffic came fromWellington Road (current designated haul route) and where some of the traffic came from westof the landfill entrance (using a portion of the future addition to the designated haul route) due totrucks ignoring the designated haul route. This report concluded that the “roadway network, inits present state, can accommodate projected increases in site traffic without the need foroperational improvements”

It is also noted the quantity of waste to be received at the landfill if service area increased will beless than the quantity of waste received in many previous years in the past due to declining wastevolumes.

All the new traffic to the site will use the designated haul routes to the landfill (see Figure 4).

Considering the above, the increase in the number of vehicles going to the W12A Landfill isexpected to have minimal or no net environmental effects.

7.0 ConsultationlNext Steps

7.1 OverviewThe public consultation program for the Environmental Screening Process is outlined in thefollowing sections. The program will allow interested persons the opportunity to participate in thescreening process by providing comments on any issues or concerns regarding the proposedproject. The City will utilize newspaper publications, direct mailings and the City website tocommunicate the Notice of Commencement of Screening, progress on the screening process, andNotice of Completion of Environmental Screening Report. Interested persons will include the W12ALandfill Public Liaison Committee (PLC), public, Aboriginal communities, and governmentagencies.

7.2 City of London Public CommitteesW12A Landfill Public Liaison Committee (PLC)

As a courtesy, and in accordance with the intent of the PLC, City staff discussed the possibility ofthe City proceeding with an Environmental Screening to make changes to the W12A Landfill’sservice area, at a regularly scheduled PLC meeting (see Appendix G). City staff discussed theCity’s intention to apply to change the service area of the W12A Landfill with the W12A LandfillPublic Liaison Committee (PLC) at four meetings (meetings 25, 26, 31 and 32). The minutes areprovided in Appendix G.

In general the PLC would prefer to not accept additional materials at the W12A Landfill; howeverthey are encouraged that should this be undertaken the proposed change is limited to pointsources of waste as opposed to an ambiguous change in the general geographic boundary of thecurrent service area. The PLC will have additional opportunities for input as part of theEnvironmental Screening. They will be included in all formal notices required as part of thescreening process and a copy of this draft Background Document will provided to the PLC for theirreview and comment.Advisory Committee on the Environment (ACE)

ACE reports to the Municipal Council, through the Planning and Environment Committee. TheAdvisory Committee on the Environment provides input, advice and makes recommendations onenvironmental matters affecting the City of London.

City staff will attend an ACE meeting to provide an overview of the Environmental ScreeningProcess and seek input.Agriculture Advisory Committee (AAC)

ACC reports to the Municipal Council, through the Planning and Environment Committee. TheAgricultural Advisory Committee provides input on agricultural and rural issues as a majorcomponent of land use planning and development, and provides liaison between agricultural andrural communities and the Municipal Council and helps to ensure that the City of London maintainsa secure, economically viable agricultural industry.

City staff will attend an ACC meeting to provide an overview of the Environmental ScreeningProcess and seek input.

Page 24

W12A Service Area Amendment Environmental Screening Process

7.3 Public ConsultationThe Environmental Screening Process requires two formal notices and four opportunities for publicconsultation.

The public consultation opportunities are:• Notice of Commencement of a Screening Project and release of Background Document;• consultation on the project description, screening criteria checklist completion, and

descriptions of potential effect;• consultation on the assessment of potential environmental effects and mitigation measures;

and,• Notice of Completion of the Environmental Screening Report.

Notifications of consultation opportunities will be issued through the following methods:• published in The Londoner newspaper (Notice of Commencement and Notice of

Completion);• notification to the PLC;• direct mailings to interested residents who asked to be part of the screening process;• direct mailings to property owners within 1,500 metres of the landfill; and• published on the City website.

Information on the Environmental Screening Process will be available on the City’s website whichwill have a dedicated page that includes:

• information on the Environmental Screening Process;• a copy of this draft Background Document;• a copy of all Notices;• a schedule of events; and,• an opportunity to comment on the project.

A copy of this draft Background Document will be provided to all residents that request a copy.

At each consultation opportunity, Staff proposed to meet with interested residents individuallyand/or in groups (depending on the preference of the residents) who want further details or whowant to speak directly to staff about any concerns or input they have. At the meetings, staff willexplain the project, provide information, answers questions and provide opportunities for residentsto provide comments.

An open house will held in September as part of the third consultation opportunity.

A list of interested persons along with comments received will be maintained and addressedthrough the screening process. Comments received will also be documented in the final screeningreport.

7.4 Aboriginal ConsultationThe Environmental Screening Process requires the proponent prepare a list of Aboriginalcommunities that may be potentially affected by or interested in the project. This list wasdeveloped in consultation with the Environmental Approvals Access and Service IntegrationBranch is presented in Table 11.

The notices mentioned in Section 6.3 will be directly mailed to each Aboriginal community includedin the list.

In April 2015 the City met with the Chief and two Councilors of the Caldwell First Nation. Thepurpose of the meeting was to build a stronger relationship between the community and the City ofLondon and to also determine which Municipal Class Environmental Assessments (MCEA’s) andEnvironmental Screenings would be of greatest interest to them. A list of ongoing and upcomingMCEA’s and Environmental Screenings was presented at the meeting including the plan toundertake an Environmental Screening Process to revise the ECA of the W12A Landfill site toexpand its service area to accept waste materials from outside of London. Each MCEA andEnvironmental Screening was not reviewed in detail at the meeting and the City will follow up withthe CaIdweIl Council regarding this Environmental Screening Process when the Notice ofCommencement is mailed out.

7.5 GovernmenUPublic Agency ConsultationA list of government agencies that may have jurisdiction or an interest in the review and approvalof this proposed project are included in Appendix H (MOECC and the Ministry of Transportation(Mb)). The first notice that will be issued to these agencies will be the Notice of Commencement.The City will also circulate draft Environmental Screening Reports to the appropriate agency
