Page 11 Tighe&Bond N1093-PO15 April 5, 2022 John Borgesi, PE, Assistant Director/Town Engineer Town of North Andover Division of Public Works 384 Osgood Street North Andover, MA 01845 Re: Proposal for Professional Engineering Services Permit Year 4 Stormwater Program Assistance Dear John, We are pleased to provide you with this proposal to continue assisting the Town of North Andover in meeting requirements of the Environmental Protection Agency's (EPA's) National Pollutant Discharge Elimination System (NPDES) Phase II Stormwater Program. The following Scope of Work provides the Town with support to complete multiple Permit Year 4 (PY4) requirements of the 2016 Small Municipal Separate Storm Sewer System (MS4) General Permit. SCOPE OF SERVICES Phase 1 - Catchment Investigations and Wet Weather Screening Tighe & Bond will begin systematic implementation of the Catchment Investigation Procedures developed as part of the IDDE Plan. Work under this Phase includes: Task 1.1 Field Work Preparation Desktop Assessment of"Complete" Catchment Areas According to Section 2.3.4.8.c.ii.i.c of the General Permit, "where catchments do not contain junction manholes, the dry weather screening and sampling shall be considered as meeting the manhole inspection requirement. In these catchments, dry weather screenings that indicate potential presence of illicit discharges shall be further investigated pursuant to [Section] 2.3.4.8.d [of the General Permit]. Investigations in these catchments may be considered complete where dry weather screening reveals no flow; no evidence of illicit discharges or SSOs is indicated through sampling results or visual or olfactory means; and no wet weather System Vulnerability Factors are identified."Tighe & Bond will review dry weather screening results and mapping to determine catchments that can be considered complete. Development of Investigation Plan We will further prepare for field work by developing electronic field forms for use in ArcGIS Online and Survey123, select catchments and outfalls to be investigated, gather input from Town staff about the presence or absence of system vulnerability factors (SVFs) within each catchment to be investigated, complete a preliminary refinement of catchment delineations for the selected catchments, and develop of a GIS mapbook of the investigation areas. The key junction manhole(s) that are identified under this Task will be noted as such in the Town's GIS mapping. For planning purposes, we will select 30 High Priority catchments for the investigation plan. We will review and confirm the investigation plan with Town staff prior to field work. 120 Front Street, Suite 7 Worcester, MA 01608 Tel 508.754.2201 Task 1.2 Dry Weather Key ]unction Manhole Inspections Tighe & Bond will perform five (5) days of field work to screen key junction manholes during dry weather conditions. We will identify and investigate up to 75 junction manholes/catch basins within catchments ranked as High Priority in the Town's IDDE Plan and after dry weather outfall screening. For budgeting purposes, we assume that 15 manholes will be inspected per day, and that 40% (30) of the key junction manholes will have dry weather flow. During inspections, we will implement the catchment investigation procedures and inspect each key junction manhole for the presence of dry weather flow and illicit discharges. We will verify and update connectivity as needed in the GIS mapping; however, if significant changes need to be made, Tighe & Bond will limit field edits and address under a future phase of work. If this occurs, we will note areas needing substantial mapping improvements in the summary report described below. If flow is present, we will use field test kits to complete in situ screening of ammonia, chlorine, and surfactants. It may be necessary to open the next upstream and downstream structures to isolate the source of flow. We will enter field observations, photos, and in-situ screening results into GIS using an iPad. If applicable, we will refine the catchment delineations in GIS after field work is completed, based on updated connectivity found in the field. Assumptions: • We will complete field work with one (1) Town staff member and one (1) Tighe & Bond staff member. Town staff will be responsible for opening structures as required and providing a municipal truck with lights for traffic control. • A glass bottle of hazardous waste (less than 1 gallon) generated with the surfactants test kits will be disposed of by the Town. • The cost of police details is not included in this proposal. Invoices will be billed directly to the Town if details are required. This proposal does not include follow-up activities to identify source, remove source, or complete confirmatory sampling. • This initial catchment investigation will not include the use of sandbags to capture trapped flow. Manholes with some evidence of an intermittent discharge will be flagged for further investigation and an approach will be discussed with Town. • If a pipe segment has been identified as having a potential illicit discharge, additional downstream investigations will only be conducted at key junction manholes to determine relative increase or decrease in flow and water quality screening results. • If a suspected illicit discharge is isolated to a specific pipe segment, Tighe & Bond will make recommendations for further action. It may be necessary for the Town to perform CCTV, smoke testing, or dye testing/dye flooding in the surrounding area to pinpoint the illicit discharge. These services are not included in this scope of work. • The Town will be responsible for any corrective action required "to identify and eliminate [any] illicit discharge as expeditiously as possible" identified in Task 2.2 and 2.3 in accordance with the timeline and record keeping requirements in Sections 2.3.4.2 and 2.3.4.8.e of the General Permit. Tighe & Bond will provide input and guidance throughout the process, if applicable. - 2 - Task 1.3 Wet Weather Outfall Screening For catchments with one or more SVF, Tighe &Bond will perform three (3) days of wet weather screening at the associated outfalls. We will use the field screening and laboratory analysis methodology similar to previous outfall sampling efforts, except in wet weather conditions. This will include collecting and sending samples to a certified laboratory for analysis of surfactants, ammonia, E. coli, and TMDL and impaired waters requirements, as well as performing in situ screening of chlorine, temperature, conductivity, salinity, and additional TMDL and impaired waters requirements if necessary. As described in Task 1.1, we will work with the Town to confirm the presence of SVFs within each catchment prior to field work. For budgeting purposes, we assume that each catchment to be investigated will have one or more SVFs and will require wet weather sampling at the outfall. We will complete the wet weather screening field work with one (1) Town staff member and one (1) Tighe & Bond staff member. Task 1.4 Summary Memorandum Tighe & Bond will summarize the work completed in a memorandum that includes a summary table and map with findings, recommendations, and a log of junction manhole and outfalls inspected. This memorandum will be added to the IDDE Plan as an appendix. Phase 2 — Phosphorus Source Identification Report Appendix H Part II.b of the General Permit requires that the Town develop a Phosphorus Source Identification Report and an evaluation of properties with potential retrofit opportunities for areas of the MS4 within the Merrimack River Watershed. The Phosphorus Source Identification Report must be complete by June 30, 2022 and submitted with the Permit Year 4 annual report due in September 2022. In Permit Year 3, the Town completed a BMP retrofit assessment in accordance with Section 2.3.6.d of the General Permit through a Merrimack Valley Planning Commission (MVPC) grant, which includes possible retrofit sites at the North Andover High School and the Town Hall parking area. Based on discussions with Town staff, the proposed recreation complex at the Atkinson School is another possibility for installation of BMPs. Additionally, Appendix H requires the Town to evaluate the properties identified under these requirements for the next planned infrastructure, resurfacing, or redevelopment activity planned for the property (if applicable) OR planned retrofit date; the estimated cost of redevelopment or retrofit BMPs; and the engineering and regulatory feasibility of redevelopment or retrofit BMPs. The Town has to provide a listing of planned structural BMPs and a plan and schedule for implementation in the Permit Year 5 Annual Report, then plan and install a minimum of one structural BMP in a catchment with high phosphorus load potential as a demonstration project within six years of the permit effective date. To meet the Appendix H requirements, Tighe & Bond will complete a phosphorus source assessment with the following elements in accordance with General Permit requirements: • Calculation of total urbanized area within the Town's jurisdiction that is within the Merrimack River watershed, incorporating updated mapping of the MS4 and catchment delineations produced pursuant to Part 2.3.4.6 of the General Permit. • All screening and monitoring results pursuant to Part 2.3.4.7, targeting the receiving water segment(s). • Impervious area and directly connected impervious area (DCIA) for the target catchment. Tighe & Bond will estimate DCIA based on EPA Guidance. • Identification, delineation, and prioritization of potential catchments with high phosphorus loading. - 3 - • Identification of potential retrofit opportunities or opportunities for the installation of structural BMPs during redevelopment. This assessment will include properties within the Merrimack River watershed, as well as the properties with possible retrofit opportunities identified by MVPC and Town staff. We will develop an overall GIS figure showing phosphorus loadings by parcel within the watershed. We will also prepare a preliminary "mapbook" showing available GIS data for the potential retrofit sites (i.e., orthophotograph site plan with soil type, groundwater depth, nearby water resources, etc. that would impact design and construction of a stormwater BMP). Tighe & Bond will meet with the Town to review the initial Retrofit Inventory developed by MVPC, impervious area and phosphorus loading analysis completed under this Phase, and preliminary mapbook, as well as discuss schedules for planned physical capital projects (including storm and sanitary sewer infrastructure projects and paving projects), current storm level of service, and other applicable ranking criteria. We will work with Town staff to priority rank the retrofit sites. It is assumed this meeting will be held in-person. After the meeting, we will perform a site visit to confirm characteristics of the top ranked properties on the Retrofit Inventory for up to five locations. For the top five properties on the final Retrofit Inventory, Tighe & Bond will prepare 11x17 planning-level site sketches that include a brief description of the recommended MS4 modification or retrofit opportunity, a conceptual design and site sketch, estimate of BMP pollutant removal, an estimate of annual operation and maintenance needs and costs, and an opinion of probable design, permitting, construction costs. Stormwater management BMPs will be optimized for phosphorus removal in accordance with TMDL requirements. Deliverables: Tighe & Bond will develop a summary report documenting the work completed under this Task. It will include the Phosphorus Source Identification Report assessment, GIS figure with phosphorus loading, retrofit site sketches, opinions of probable cost, and a plan and schedule for implementation of the structural BMPs under the Retrofit Inventory and Impaired Waters requirements. We will provide an agenda and handouts for the meeting with Town staff. Phase 3 — BMP Inspections In accordance with Section 2.3.7.a.iii.6 of the General Permit, all Town BMPs (excluding catch basins) must be inspected annually. As part of the Town-wide Operations and Maintenance (O&M) Plan developed in Permit Year 2, Tighe & Bond prepared a standard operating procedure (SOP) for BMP inspections and maintenance consistent with the Massachusetts Stormwater Handbook. We will use this SOP as a baseline to develop an electronic inspection form that can be used to log inspections. The Town has 56 stormwater BMPs, of which 19 are noted as detention basins, and 115 open channels (swales, ditches) in the current GIS mapping. Two (2) Tighe & Bond staff will complete up to seven (7) days of field work to complete inspections at the 19 mapped detention basins and 115 open channels. We assume approximately 10 basins and 20 open channels can be inspected per field day. We will include photographs of the BMPs and open channels and log any deficiencies found during the inspections. If new municipal detention basins are discovered during field work, we will add them to the GIS mapping and complete an inspection. After the inspections, we will review data collected to make recommendations and a brief update to the Town-wide O&M Program, including a 5-year action plan for prioritized BMP maintenance, a recommended inspection schedule based on BMP type, and an updated BMP inspection and maintenance SOP if needed. - 4 - Assumptions: • Note that these inspections will focus on stormwater basins and open channels only and inspections at the 37 other proprietary units or recharge BMP types included in the GIS will not be completed this year, as these BMPs require identification of specific O&M manuals to confirm inspection procedures and needed equipment. However, we will identify these BMPs in the recommended inspection schedule and updated SOP noted above. We assume the Town will compile the O&M manuals for these BMPs and they can be added to the inspection program in a future permit year or inspected by the Town to confirm any maintenance needs. • It is assumed Town staff will complete the annual inspections of municipal stormwater BMPs in future Permit Years in accordance with General Permit requirements. As such, it is recommended that Engineering Division staff attend a portion of the BMP inspections as feasible to learn the BMP inspection process and field form. Phase 4 — Drainage System Mapping and GIS Support Tighe & Bond will provide up to 45 hours of GIS support to the Town, which may include, but is not limited to, the following: • Ongoing improvements for data reliability and functionality of ArcGIS Online applications and overall drainage GIS. • Additional ESRI applications needed for the Town's field efforts, data management, and MS4 program tracking, including under the IDDE Program and municipal good housekeeping program (e.g., catch basin cleaning, quarterly SWPPP inspections). Phase 5 — Permit Year 4 Annual Report and SWMP Update Per Section 4.4 of the General Permit, the Permit Year 4 Annual Report is due to the EPA and the Massachusetts Department of Environmental Protection (MassDEP) by September 28, 2022. Tighe & Bond will assist the Town with preparation of the Annual Report, including the following tasks: • Use EPA's reporting template to document the Town's actions toward meeting stormwater program goals and milestones. This includes completing a "self- assessment," which is an evaluation of activities completed during Permit Year 4 compared to the requirements of the General Permit. • Attend one meeting with Town staff to aid in development of the annual report, and specifically to verify and document stormwater management activities completed during Permit Year 4. This meeting will be held remotely via conference call and screen sharing. • Deliver the Annual Report to the Town for certification. Upon certification, Tighe & Bond will electronically submit the report to EPA and MassDEP. • Compile documentation, with the Town's assistance, for Permit Year 4 activities to be added to the Town's Stormwater Management Program record keeping files. After Annual Report submission, an updated Stormwater Management Plan will be provided and should be posted online. We may also prepare updates to the Town's IDDE Plan and/or inventories of buildings, facilities, parks, open space, and vehicles and equipment developed for the Town-Wide Operations and Maintenance Plan, as applicable based on changes to the program in Year 4, for the Town's internal record keeping. - 5 - u, While preparation and/or submittal of the items included in our Scope of Work are required by the General Permit, an on-time preparation/submittal does not guarantee overall program compliance in the eyes of the EPA, nor does it eliminate the possibility of a comprehensive compliance audit. ASSUMPTIONS AND EXCLUSIONS The following items are not included in this Scope of Work: • Section 2.3.6 (parts b and c) of the General Permit requires the development of reports assessing local guidelines, bylaws, regulations, and procedures that affect the creation of impervious cover and use of green infrastructure by June 30, 2022. The Town of North Andover is participating in the MVPC grant to complete a Street Design and Parking Lot Guidelines Assessment Report and Green Infrastructure Feasibility Assessment Report, which we assume will meet General Permit requirements. We suggest carefully evaluating the recommendations for consistency with Town goals and schedules, as the General Permit requires that "the permittee shall implement all recommendations, in accordance with the schedules, contained in the assessment [and] ... report in each annual report on the status of this assessment including any planned or completed changes to local regulations and guidelines". • Section 2.3.6 (part d) of the General Permit requires that the Town identify a minimum of five Town-owned properties that could potentially be modified or retrofitted with BMPs by June 30, 2022. Last Permit Year, North Andover participated in a MVPC grant' to complete this assessment, which we assume is sufficient to meet General Permit requirements. SCHEDULE We will work with town staff to determine a suitable schedule for interim project milestones. The Scope of Work will be complete no later than June 30, 2022. FEE Tighe & Bond will perform these services for a lump sum fee of $76,000, invoiced monthly based upon percentage complete. In the event that the scope of work is increased for any reason, the lump sum fee to complete the work shall be mutually revised by written amendment. The summary table below provides the anticipated break out of the project by Phase and is presented to give the Town a better understanding of how the project budget was developed. Invoices will be submitted based on the total project fee and not individual line item budgets. Phase Description Budget 1 Catchment Investigations & Wet Weather Screening $28,000 2 Phosphorus Source Identification Report $19,500 3 BMP Inspections $17,000 4 Drainage System Mapping & GIS Support (45 hours) $6,000 5 Permit Year 4 Annual Report and SWMP Update $5,500 Total Fee $76,000 MassGEP MSG Municipal Assistance Grant Report, Merrimack Valley Stormwater Collaborative, June 30, 2021.
