Request for Determination of Applicability MassDOT Impaired Waters Remediation ! North River ! Sergeant James Ayube Memorial Drive(Bridge Street Bypass), Salem, Massachusetts • 1 .0 INTRODUCTION • • This Request for Determination of Applicability(RDA) is being submitted by the Massachusetts • Department of Transportation - Highway Division (MassDOT) pursuant to the Massachusetts Wetlands ! Protection Act(MWPA; MGL Ch. 131, s. 40) regulations (310 CMR 10.00 at seq.) for the impaired waters remediation project for the North River located along Sergeant James Ayube Memorial Drive (Bridge ! Street Bypass) in Salem, Massachusetts (see Figure 1 — USGS Locus and Figure 2— Project Overview). ! MassDOT has specific obligations to manage stormwater discharges from its roadways and properties ! through its National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer • System (MS4) General Permit. The United States Environmental Protection Agency(EPA) Region 1 has recently required three modifications to MassDOT's Stormwater Management Plan developed under its ! MS4 NPDES permit: 1)to describe control measures and best management practices for impaired • waters identified under Section 303(d) of the federal Clean Water Act without Total Maximum Daily Load • (TMDL) restrictions, 2) to assess within five years all waters with TMDL restrictions, and 3) to propose schedules for the implementation of required Best Management Practices (BMPs) as they are identified • and to implement these BMPs within five years. ! MassDOT has recently undertaken analyses to address stormwater runoff to impaired waters in urban ! areas covered by the MS4 permit. The overriding purpose of the Impaired Waters Remediation Program ! is to identify and prioritize impaired waterbodies where MassDOT stormwater runoff has the most impact, ! identify the appropriate BMPs to address the situation, complete the design and permitting of the BMPs and construct them as quickly as possible. MassDOT Highway Division conducted an Impaired Waters Assessment of the North River. This assessment utilized impervious cover as a surrogate for stormwater related pollutants, estimating ! potential stormwater impacts from MassDOT discharges on the river.This assessment also evaluated the ! effectiveness of existing stormwater BMPs to develop a target level of impervious cover reduction required to ensure that stormwater is not the cause of the impairments. The assessment recommended • the modification of an existing BMP to reduce stormwater contributions of pollutants from MassDOT • property to the maximum extent practicable.This RDA is submitted in support of the proposed ! modification. ! 1 PROJECT DESCRIPTION • • 2.1 SITE DESCRIPTION • ! Located in the northbound shoulder of Sergeant James Ayube Memorial Drive (Bridge Street Bypass), • directly east of the North River between Northey Street and Conant Street, is an existing detention basin that was constructed in 2008 as part of the Bridge Street Bypass project. The basin's overall footprint is roughly 17,500 square feet. A 1 V:2H side slope leads down to a 12,000-square-foot sloped basin bottom. • Stormwater flows enter the basin by way of seven flared end structures, four of which enter the basin ! . directly while the remaining three discharge to a drainage ditch that conveys flows to the basin. No • sedimentation forebays are provided at any of the inlet structures. The outlet structure consists of a ! headwall and an 18-inch outlet pipe, with its invert at the basin bottom, located on the western side of the ! ! Q TETRA TECH 1 • • • • • Request for Determination of Applicability MassDOT Impaired Waters Remediation • North River • Sergeant James Ayube Memorial Drive(Bridge Street Bypass), Salem, Massachusetts • basin that extends to the North River beneath the roadway and railroad. The basin does not include any • overflow/spillway areas, an outlet control structure, or other characteristics that would indicate it is providing anything more than incidental water quality treatment. Additional features at the basin include a • 4-foot high chain link fence along the bikeway/sidewalk for pedestrian safety. • According to MassDOT's record plans, approximately 1.1 acres of pavement from Sergeant James Ayube • Memorial Drive discharge into the basin. The record plans also indicate that roadway runoff from roughly • 0.9 acres of adjacent residential streets is directed to the basin. • The investigation of the existing detention basin, drainage ditches and associated drainage infrastructure • confirmed that they were generally constructed in accordance with the design plans. Both the existing • detention basin and ditches were well vegetated, which includes the invasion of Phragmites within the basin's footprint. A noticeable amount of trash and debris was encountered, with a significant amount of • buildup adjacent to the headwall and 18-inch outlet pipe. • 2.2 PROPOSED WORK • • The proposed project consists of the conversion of the existing detention basin into an infiltration basin. • By definition, an infiltration basin stores the recharge volume or water quality volume below the lowest • outlet of the basin, and allows it to infiltrate into the underlying soils over a period of time following a storm event. MassDEP requires pretreatment of infiltration BMPs. With adequate pretreatment, an infiltration • basin is credited with an 80%Total Suspended Solids (TSS) removal rate. According to MassDEP, • pollutant removal efficiencies are 50% -60%for Total Nitrogen, 60% - 70%for Total Phosphorus, 85% - • 90%for Metals, and 90%for Pathogens. • Based on field observations,the bottom of the existing detention basin is approximately 3 feet above the • estimated seasonal high water table, providing sufficient separation to groundwater for the conversion to an infiltration basin. Furthermore, the soils encountered generally consist of"Sandy"soils demonstrating • an adequate infiltration rate. • Modifications to the existing detention basin consist of adding sediment forebays or pretreatment • manholes at each inlet location to provided adequate pretreatment, constructing an outlet control • structure in place of the existing headwall to provide temporary storage of the water quality volume, achieving peak rate control and offering a drawdown device for maintenance, as well as some minor • regrading to incorporate a flat basin bottom. As part of the regrading effort, since this area has acted as a • detention basin without pretreatment for the past seven years, the topsoil layer within the limits of the • basin bottom will be removed and replaced with new material meeting the specifications of ordinary borrow and/or loam borrow. • • Work within Wetlands Protection Act jurisdiction includes modifications to the existing detention basin located east of the North River on the east side of the Bridge Street Bypass, which is located within the • 200-foot Riverfront Area of the North River. Project plans are included in Appendix A. • • • • • ®TETRA TECH 2 - • • • • • Request for Determination of Applicability MassDOT Impaired Waters Remediation • North River • Sergeant James Ayube Memorial Drive(Bridge Street Bypass), Salem, Massachusetts • 1 WETLAND RESOURCES • • Within and in the vicinity of the project area, there are four resource areas regulated under the MWPA. • These include Coastal Bank, Land under the Ocean (LUO), Land Subject to Coastal Storm Flowage • (LSCSF), and Riverfront Area, all associated with the North River. • The proposed project is located east of the North River on the east side of the Bridge Street Bypass and • is located within the 200-foot Riverfront Area of the North River. • According to the applicable Flood Insurance Rate Map for Essex County, Massachusetts (Map Number 25009C0419G, dated July 16, 2014), the proposed project is not located within the 100-year floodplain • (Figure 3), nor is it located within the 100-foot buffer zone of the Bank of the North River. • 3.1 OTHER RESOURCES • • The proposed project is not located within Priority Habitat of Rare Species or Estimated Habitat of Rare • Wildlife, as designated by the Massachusetts Natural Heritage and Endangered Species Program (MA • NHESP).There are no Certified or Potential Vernal Pools, also designated by MA NHESP, in the vicinity • of the project area. • The project is not located within an Outstanding Resource Water(ORW), Designated Port Area (DPA), or • an Area of Critical Environmental Concern (ACEC). • Mitigation measures will be put in place to protect the resource areas in the vicinity of the project. • Overall,the project will result in a significant environmental benefit. • 1 IMPACTS • • The proposed project is located in Riverfront Area. In accordance with the Riverfront Area General • Performance Standards (310 CMR 10.58 (4)), the proposed project will have no significant adverse • impact on the Riverfront Area. • The proposed project will not impact specified habitat sites of rare wetland or upland, vertebrate or • invertebrate species. The proposed project will have no impact on vernal pool habitat. • There is no practicable and substantially equivalent economic alternative to the proposed project with less • adverse effects. • Within 200-foot Riverfront Areas, alteration of up to 5,000 square feet or 10%of the Riverfront Area within the lot(whichever is greater) may be allowed. However, under 310 CMR 10.58 (4) (d), those areas used • for structural stormwater management measures are excluded from the calculation of square footage of • alteration of Riverfront Area. As such, there will be no impact to wetland resource areas from this • project. • • • • • O TETRA TECH 3 • • • • • Request for Determination of Applicability MassDOT Impaired Waters Remediation • North River • Sergeant James Ayube Memorial Drive(Bridge Street Bypass), Salem,Massachusetts • 1 CONSTRUCTION MITIGATION • • Construction mitigation is provided, as described below. • Prior to work commencing on the site, there will be a pre-construction conference with the contractor. The • purpose of this meeting will be to coordinate the best methods for erosion and sedimentation control, • protection of wetland resource areas in the project vicinity, and other construction-related issues. In general, the following sequence of events will occur: • • A temporary compost filter tube will be placed at the location of the outlet pipe until the pre- treatment structures and outlet control structure have been installed to limit the migration of sediment laden runoff into the North River. Compost filter tubes will also be placed around any • temporary topsoil stockpile area. • Erosion and sediment control devices will be inspected at least once every seven (7) calendar • days OR at least once every fourteen (14) calendar days and within 24 hours of the end of a • storm event of 0.5 inches or greater. • During construction, disturbed areas will be kept to a minimum and vegetative stabilization of • these areas will occur as soon as possible. • If applicable, temporary seeding, mulching, or other suitable stabilization measures will be used • to protect exposed areas should unprotected soils remain exposed for prolonged periods. • 1 CONCLUSION • • The proposed stormwater management improvement project includes modifications to the existing • stormwater BMP located along the Bridge Street Bypass in Salem. The project is designed as part of the • MassDOT Impaired Waters Remediation Program to reduce pollution contributions from stormwater. The proposed BMP improvements effectively reduce the impervious cover of the stormwater contributing area • to the impaired segment of the North River by capturing and treating stormwater rather than allowing it to • directly discharge into the river untreated. Under 310 CMR 10.58 (4) (d), areas used for structural • stormwater management measures are excluded from the calculation of square footage of alteration of Riverfront Area. Mitigation measures will be put in place to protect the resource areas in the vicinity of • the project. Overall, the project will result in a significant environmental benefit. MassDOT respectfully • requests that the Salem Conservation Commission find that these measures protect and promote the interests of the MWPA and issue a Negative Determination approving the work described in this RDA. • • • • • • • • • D TETRA TECH 4 • • • • • • • • • • • • • • • • • • • • o • • • • • • • • • • • • • • • • • • ' • • • • • � • ' w • • • • • • • • • • • • • • • • • • • • • • • • Figures • • • • • • • • • • • ...
