Chicopee Conservation Commission 274 Front Street Fourth Floor, City Hall Annex Chicopee, MA 01013

Subject: Notice of Intent Application Connecticut River Stormwater Improvements and the I-391 Resurfacing Project Chicopee, Massachusetts

Dear Commission members,

On behalf of the Massachusetts Department of Transportation (MassDOT) - Highway Division, AECOM respectfully submits nine copies (including one original and eight copies) of this Notice of Intent (NOI) for proposed stormwater improvements for review under the Massachusetts Wetlands Protection Act (WPA) and Implementing Regulations.

Improvements to existing stormwater management systems are proposed to be located adjacent to I-391 south on- and off-ramps at the I-391/Grattan Street (Rt. 141) Interchange (Exit 4) and at the on- and off-ramps at Exit 2 in Chicopee. The stormwater retrofits are part of the MassDOT Impaired Waters Program aimed at mitigating stormwater discharges to waterbodies through targeted upgrades to stormwater systems and installations of stormwater Best Management Practices (BMPs). The purpose of the stormwater retrofits is to improve water quality within the Connecticut River Watershed.

I-391 resurfacing work consisting of repaving and resurfacing of the roadway from Main Street in Holyoke to the I-391/Rt. 116 Interchange (Exit 2) on-ramp to I-391 north in Chicopee is also planned. This work is exempt from the WPA, as discussed in the attached narrative.

While six of the proposed stormwater BMP sites are located within the town of Chicopee, only one site (BMP #6) is located within an area subject to protection under the WPA (100-foot Buffer Zone). The construction of the proposed stormwater BMP will provide treatment of stormwater and attenuate flows prior to discharging to the Connecticut River. Project impacts have been minimized to the maximum extent practicable and no wetlands will be directly impacted from the proposed project activities.

Details of the construction activities are provided in the attached application and figures. Please advertise this matter and place it on the agenda for the August 15, 2018 Conservation Commission hearing. Enclosed with the NOI is a check made payable to the Town of Chicopee for $200.00 for the advertising fee and a check for the town share of the filing fee of $262.50. A check for the state filing fee for the amount of $237.50 has been sent to the Commonwealth of Massachusetts lockbox. We look forward to meeting with the Conservation Commission to discuss the proposed project at the hearing. If you have any questions, please do not hesitate to contact me at (978) 905-3219 or Jennifer Doyle-Breen, AECOM Associate Vice President, at (978) 905-2968.

1.0 Introduction

On behalf of the Massachusetts Department of Transportation – Highway Division (MassDOT), AECOM is submitting this Notice of Intent application (NOI) for the Connecticut River Stormwater BMP and I-391 Resurfacing Project, pursuant to the Massachusetts Wetlands Protection Act (WPA; MGL Ch. 131 s. 40) and its implementing regulations (310 CMR 10.00). Abutter notification is not required for projects proposed by MassDOT pursuant to Chapter 472 of the Acts of 1993 as approved on January 13, 1994. The location and extent of the work areas is shown in the figures in Attachment A.

The Connecticut River BMP and I-391 Resurfacing Project is being completed to maintain the condition of the Interstate 391 roadway and improve the quality of the stormwater runoff to the Connecticut River. The roadway resurfacing work is important to maintain a safe condition for the travelers utilizing this roadway. The planned resurfacing work consists of resurfacing and repaving I-391 from the Connecticut River bridge (Holyoke/Chicopee town line at mile marker 4.5) near the project’s northern end to the I-391/Route 116 Interchange (Exit 2) in Chicopee at the project’s southern end (mile marker 0.8) for a total resurfacing/repaving distance of 3.7 miles within Chicopee. These resurfacing and repaving activities are exempt from the MA Wetlands Protection Act (WPA) as described further below.

Work within Chicopee also includes improvements to existing stormwater management systems located adjacent to I-391 south on- and off-ramps at the I-391/Grattan Street (Route 141) Interchange (Exit 4) and at the on- and off-ramps at Exit 2 in Chicopee. The stormwater retrofit work is part of the MassDOT Impaired Waters Program aimed at mitigating stormwater discharges to waterbodies through targeted upgrades to stormwater systems and installations of stormwater BMPs. The purpose of the BMP work is to improve water quality within the Connecticut River Watershed. The BMP work will include construction of vegetated water quality swales and infiltration and exfiltrating bioinfiltration basins. The construction of the proposed stormwater BMPs will provide treatment of stormwater and attenuate flows prior to discharging to the Connecticut River. The nearby river segment that this area drains to (MA34-05 of the Connecticut River) is currently impaired for Escherichia coli, PCB in fish tissue, and total suspended solids (TSS). It has been determined that direct discharge of untreated stormwater from MassDOT roadways contributes to the impairment of this river segment. The capture and treatment of this stormwater will have the same efficacy as removing a portion of the impervious surface contributing stormwater to the project area. The construction of the proposed stormwater BMPs will provide treatment of stormwater and attenuate flows prior to discharging to the Connecticut River. The proposed stormwater BMPs located within Chicopee are in the vicinity of I-391, on the east side of the Connecticut River. One BMP is located within 100 feet of a wetland. Additional BMPs and /or resurfacing are planned for Holyoke, West Springfield, and Agawam.

Project component exemptions and additional jurisdictional details are discussed further below.

A00860 - 23 Proposal No. 607560 - 106915

2.0 Exempt Resurfacing Activities

Resurfacing activities along I-391 are proposed to improve and maintain the condition of the roadway for driver accessibility and safety. The resurfacing work in Chicopee extends along I-391 from just south of the intersection with Route 116 to the Connecticut River Bridge that crosses to Holyoke. These activities include: full width micromill and overlay; replacing scored concrete pavement at gores with milled rumble strips and other rumble strip work; placing final pavement markings and slotted pavement markers; cleaning, replacing, and securing catch basin grids and manhole covers as needed; removing and resetting of granite edging as needed; upgrading selected existing guardrails; selected pedestrian ramp and sidewalk construction/reconstruction; replacement of traffic data collection stations; traffic management; and other incidental items. The extent of these improvements in Chicopee is shown in the locus figure and in Figures 3 through 5 in Attachment A. All of the resurfacing work will be located within existing paved roadways.

Although a portion of resurfacing activities will be located within the 100-Foot Buffer Zone, these activities solely within Buffer Zone (beyond other resource areas such as Riverfront Area) are not otherwise subject to regulation under M.G.L. c. 131, § 40 as indicated in 310 CMR 10.02(2)(b)1 provided that the work (as prescribed in 310 CMR 10.02(2)(b)2.a. through q) is performed “in a manner so as to reduce the potential for any adverse impacts to the resource area during construction, and with post-construction measures implemented to stabilize any disturbed areas”. 310 CMR 10.02(2)(b)2.p includes: “Pavement repair, resurfacing, and reclamation of existing roadways within the right-of-way configuration provided that the roadway and shoulders are not widened, no staging or stockpiling of materials, all disturbed road shoulders are stabilized within 72 hours of completion of the resurfacing or reclamation, and no work on the drainage system is performed, other than adjustments and/or repairs to respective structures within the roadway”.

A portion of resurfacing activities located in the vicinity of the Chicopee and Connecticut River bridges and a perennial stream crossing will occur within Riverfront Area. However, according to 310 CMR 10.58(6), maintenance of roads (limited to repairs, resurfacing, repaving, but not enlargement) in existence on August 7, 1996 within Riverfront Area is allowed without the filing of a Notice of Intent, but not when such work is within other resource areas or their buffer zones except as provided in 310 CMR 10.58(6)(b). 310 CMR 10.58(6)(b) includes certain minor activities as identified in 310 CMR 10.02(2)(b)1. 310 CMR 10.02(2)(b)1 references minor activities as described in 310 CMR 10.02(2)(b)2. 310 CMR 10.02(2)(b)2p includes “Pavement repair, resurfacing, and reclamation of existing roadways within the right-of-way configuration provided that the roadway and shoulders are not widened, no staging or stockpiling of materials, all disturbed road shoulders are stabilized within 72 hours of completion of the resurfacing or reclamation, and no work on the drainage system is performed, other than adjustments and/or repairs to respective structures within the roadway”. Therefore, the proposed resurfacing work within Riverfront Area is exempt from the WPA.

None of the resurfacing work is located in any other MA WPA resource areas. The resurfacing work is located in MA NHESP mapped habitat. MassDOT is currently

A00860 - 24 Proposal No. 607560 - 106915

separately consulting with MA NHESP regarding protected habitat, however a copy of this NOI is being provided to NHESP as a courtesy.

3.0 Existing Conditions Near the BMP Work Areas

The stormwater improvement portions of the project area contained in Chicopee are comprised of eleven proposed BMP sites (BMP #s 3, 6, 7, 10, 12, 14, 17, 18, 19, 23A, and 23B) (see Attachment A - Figure 1, Locus Map for locations). BMP #s 3, 6 and 7 are located in the vicinity of the I-391/Route 141 Interchange (Exit 4). BMP #s 10, 12 and 14 are located in the vicinity of the I-391/Route 116 Interchange (Exit 2). BMP #s 17, 18, 19, 23A, and 23B are located in the vicinity of the I-391/ I-91 interchange. BMP#s 3, 10, 12, 14, 17, 18, 19, 23A, and 23B are located outside the jurisdiction of the WPA and are not discussed further below. Wetland resource areas in the vicinity of the proposed stormwater BMP #s 6 and 7 are shown in Attachment A Figure 1.

Wetland resources were further defined via field delineation in the immediate vicinity of the proposed activities for BMP #6 and #7 because of their proximity to these resources. Bordering Vegetated Wetland (BVW) boundaries were delineated in accordance with the Massachusetts Wetlands Protection Act regulations (310 CMR 10.00) and MassDEP’s publication entitled “Delineating Bordering Vegetated Wetlands under the Massachusetts Wetlands Protection Act.”

3.1 BMP #6 BMP #6 is a proposed exfiltrating bioinfiltration basin with total limits of work of approximately 0.27 acres (11,760 SF). This BMP would be located within the area enclosed by I-391 southbound to the south and east and the I-391 on- and off-ramps to/from Route 141 to the west and north, respectively. The existing vegetation in the area proposed for BMP #6 is primarily comprised of a variety of grasses, with an existing concrete drainage swale running generally north-south through the limits of work, and a border of trees and shrubs along the western side of the limits of work. The limits of work for BMP #6 are shown in Attachment A, Figure 2.

A BVW located adjacent to the proposed BMP #6 was demarcated in the field with wetland flag series “S6-A” (Attachment A – Figure 2; Attachment C-Sheet #9). The intermittent stream and drainage that flow into this wetland supply it with water. The intermittent stream emerges from a headwall at the southeast extent of the wetland and flows to another headwall at the northwestern extent of the BVW. It is joined by two concrete swales that are connected to nearby stormwater collection systems. These swales convey runoff to the BVW. This wetland is dominated by common reed (Phragmites australis) and reed canary grass (Phalaris arundinacea) and includes some Graminae spp. (roadside fescues and other grasses) and sensitive fern (Onoclea sensibilis). Vegetation within the adjacent upland of this BVW includes assorted grasses, with trees and shrubs located just outside of the western extents of the BVW area. The 100-foot Buffer Zone extends from BVW “S6” onto the northern portion of the BMP #6 limits of work.

A00860 - 25 Proposal No. 607560 - 106915

3.2 BMP #7 BMP #7 is a proposed exfiltrating bioinfiltration basin with total limits of work of approximately 0.47 acres (20,470 SF). The area where BMP #7 limits of work are proposed is located within the northwestern corner of the infield area of the I-391 SB off-ramp to Route 141. This area is primarily comprised of grass, with woody shrubs and trees located in the northwestern portion of the limits of work and along the northeastern boundary. Existing concrete drainage structures direct highway stormwater runoff to a stream and associated wetland southwest of the limits of work.

A BVW associated with an intermittent stream located to the southwest of BMP #7 was demarcated in the field with wetland flag series “WL1-100 through WL1-101” and “WL1-201 through WL1-207” (Attachment A). The intermittent stream, which flows south to north through a culvert, was demarcated in the field with stream flag series “S1-100 through S1- 104”. The stream enters the wetland through a culvert near S1-100 and loses definition through the wetland. Toward the downstream end of the wetland, the stream collects in a concrete swale and exits the study area via another culvert. The wetland is dominated by common reed (Phragmites australis) and includes common jewelweed (Impatiens capensis) and sensitive fern (Onoclea sensibilis). Vegetation within the adjacent upland of this BVW includes crown vetch (Securigera varia) and American pokeweed (Phytolacca americana). The site is located outside of any areas subject to jurisdiction under the MA Wetlands Protection Act, including the 100-foot Buffer Zone (see Attachment A – Figure 2). As a result, BMP #7 is not further described below.

4.0 Proposed Stormwater Improvements within WPA Jurisdictional Areas

The only BMP located within a jurisdictional area under the WPA (and therefore the subject of this NOI) is BMP #6. The proposed BMP 6 is located within the grassy area enclosed by I-391 southbound to the south and east and the I-391 on- and off-ramps to/from Route 141 to the west and north, respectively. The proposed design for the BMP involves the removal of a portion of an existing concrete drainage swale. Stormwater runoff from the existing drainage system will then be redirected to a new sediment forebay prior to discharging to a new exfiltrating bioinfiltration basin. The purpose of this BMP system is to improve the quality of water discharged to receiving waters that ultimately drain to the Connecticut River located to the west of the project area and to control the water quality treatment volume. The exfiltrating bioinfiltration area is well suited for use at the proposed site. Overflow will be directed to an existing stormwater channel and wetland area located adjacent to BMP 6 (see Attachment C for further details).

Exfiltrating bioinfiltration cells (also called rain gardens in residential applications) are shallow depressions filled with sandy soil topped with a thick layer of mulch and planted with dense native vegetation. Stormwater runoff is directed into the cell via piped or sheet flow. The runoff percolates through the soil media that acts as a filter. Exfiltrating bioinfiltration areas can provide excellent pollutant removal for the “first flush” of

A00860 - 26 Proposal No. 607560 - 106915

stormwater runoff. Exfiltrating bioinfiltration areas remove pollutants through filtration, microbe activity, and uptake by plants; contact with soil and roots provides water quality treatment better than conventional infiltration structures.

Once the exfiltrating bioinfiltration basin construction has been completed, the stormwater BMP will be seeded with the sediment forebay and exfiltrating bioinfiltration basin seed mix depicted below. The planting schedule is designed to provide soil stabilization and reduce potential erosion (see landscape details in Attachment C). Areas disturbed for construction beyond the exfiltrating bioinfiltration basin will be seeded with an appropriate upland seed mix.

The BMP does not generate any new discharges to receiving waters or the Connecticut River. No new impervious surfaces are proposed and the volume of flow currently discharging to Connecticut River will not be increased.

Sediment Forebay and Exfiltrating Bioinfiltration Basin Seed Mix Percent by Weight Common/Scientific Name 25.00% Fox Sedge, PA Ecotype (Carex vulpinoidea, PA Ecotype) 25.00% Deertongue, ‘Tioga’ (Panicum clandestinum Dichanthelium c. ‘Tioga’) 20.00% Virginia Wildrye, PA Ecotype (Elymus virginicus, PA Ecotype) 20.00% Switchgrass, ‘Shawnee’ (Panicum rigatum, ‘Shawnee’) 5.00% Autumn Bentgrass, PA Ecotype (Agrostis perennans, PA Ecotype) 2.00% Ticklegrass (Rough Bentgrass), PA Ecotype (Agrostis scabra, PA Ecotype) 1.00% Soft Rush (Juncus effusus)

1.00% Path Rush, PA Ecotype (Juncus tenuis, PA Ecotype) 1.00% Green Bulrush, PA Ecotype (Scirpus atrovirens, PA Ecotype)

A00860 - 27 Proposal No. 607560 - 106915

5.0 Regulated Area Impacts

5.1 100-Foot Buffer Zone Construction activities at BMP #6 will result in approximately 6,960 square feet of disturbance to the 100-foot Buffer Zone (Attachment A - Figure 2). The existing impervious concrete drainage swales will be removed in the area. Two check dams will be added and the area will be regraded to create a sediment forebay and an exfiltrating bioinfiltration basin that will both serve to improve the water quality of the runoff entering into the wetland and stream. The removal of concrete and increased retention time will improve the infiltration function of the Buffer Zone.

5.2 NHESP/ Protection of Rare Species According to the MassGIS data layers, the stormwater BMPs are not within any mapped Area of Critical Environmental Concern (ACEC) and there are no Certified Vernal Pools within the project area. According to the Massachusetts Natural Heritage & Endangered Species Program (NHESP) Atlas and MassGIS datalayers (8/2017), no BMPs are proposed within Estimated or Priority Habitat.

5.3 Compliance with Massachusetts Stormwater Policy A Stormwater Report and Stormwater Checklist have been prepared and are attached to this narrative as Attachment D. The project has been designed and will be constructed and installed in accordance with the MA Stormwater Management Standards.

In addition, according to 310 CMR 10.04, the project qualifies as a “redevelopment” project. For purpose of the Stormwater Management Standards as provided in 310 CMR 10.05(6)(k) through (q), redevelopment is defined to include the following projects: (a) maintenance and improvement of existing roadways including widening less than a single lane, adding shoulders, correcting substandard intersections, improving existing drainage systems and repaving; (b) development, rehabilitation, expansion and phased projects on previously developed sites provided the redevelopment results in no net increase in impervious area; and (c) remedial projects specifically designed to provide improved stormwater management such as projects to separate storm drains and sanitary sewers and stormwater retrofit projects.

The project does not involve any new stormwater discharges to the Connecticut River or any other wetland resource area. No new impervious surfaces are proposed for the project. The volume of flow currently discharging to the Connecticut River would not be increased. In fact, the proposed BMP# 6 stormwater treatment system is designed to treat and infiltrate stormwater in place.

A00860 - 28 Proposal No. 607560 - 106915

6.0 Mitigation

6.1 Erosion and Sediment Controls An erosion and sedimentation control program will be implemented to minimize impacts to the adjacent BVW “S6” during the construction phase of the project. The program incorporates BMPs specified in guidelines developed by the DEP and presented in the Massachusetts Erosion and Sediment Control Guidelines for Urban and Suburban Areas: A Guide for Planners, Designers, and Municipal Officials (DEP, 1997) and U.S. Environmental Protection Agency (EPA) document, Interim Developing Your Stormwater Pollution Prevention Plan: A Guide for Construction Sites (Office of Water Report EPA 833-R-060-04, 2007).

Proper implementation of the erosion and sedimentation control program will:

1. Minimize exposed soil areas through sequencing and temporary stabilization; 2. Place structures to manage stormwater runoff and erosion; and 3. Establish a permanent vegetative cover for other forms of stabilization as soon as practicable.

Non-Structural Practices Non-structural practices to be used during construction include temporary stabilization, temporary seeding, permanent seeding, pavement sweeping (if necessary), and dust control. These practices will be initiated as practicable in appropriate areas at the site.

Temporary Stabilization Any areas of exposed soil or stockpiles that will remain inactive for more than 14 days will be covered with a layer of straw mulch.

Permanent Seeding Upon completion of final grading, any bare ground outside of the infiltration basins and within the limits of work will be seeded with a native upland restoration seed mix. The area within the infiltration basins will be seeded with the basin seed mix discussed above.

Pavement Sweeping

Roadways adjacent to the project site shall be swept as needed during construction. The sweeping program will remove sediment and other contaminants directly from paved surfaces before their release into stormwater runoff. Pavement sweeping has been demonstrated to be an effective initial treatment for reducing pollutant loading into stormwater (per Demonstration of Nonpoint Pollution Abatement through Improved Street Cleaning Practices, U.S. EPA, 1979).

A00860 - 29 Proposal No. 607560 - 106915

Structural Practices Structural erosion and sedimentation controls to be used on the site include erosion control barriers. Prior to any ground disturbance, an erosion control barrier consisting of compost filter tubes would be installed at the limit of work. As construction progresses, additional barriers would be installed around the base of stockpiles and other erosion prone areas as necessary. Limit of work erosion controls are depicted on the Project Plans in Attachment C.

If sediment has accumulated to a depth which impairs proper functioning of the barrier, it would be removed by hand or by machinery operating upslope of the barriers. This material would be either reused at the site or disposed of at a suitable offsite location. Any damaged sections of erosion control will be repaired or replaced immediately upon discovery.

7.0 Summary

The project has been designed to improve the water quality of the Connecticut River by capturing and treating adjacent roadway runoff that currently directly enters the river untreated. The project is contained entirely within the state highway layout with no direct impacts to any wetland resource areas. The only impact to an area subject to the WPA is the 100-foot Buffer Zone located within a portion of BMP #6. The BMP design minimizes the impact on the Buffer Zone while maximizing the effectiveness of the BMP within a limited project area. The project would result in an overall benefit to the area and dually improve both the stormwater quality and resource area functions.

MassDOT respectfully requests that the Chicopee Conservation Commission find these measures adequately protective of the interests identified in the WPA and issues an Order of Conditions approving the work described in this NOI and as shown on the accompanying plans.

A00860 - 30 Proposal No. 607560 - 106915

1.0 Introduction

Work within Chicopee also includes improvements to existing stormwater management systems located adjacent to I-391 south on- and off-ramps at the I-391/Grattan Street (Route 141) Interchange (Exit 4) and at the on- and off-ramps at Exit 2 in Chicopee. The stormwater retrofit work is part of the MassDOT Impaired Waters Program aimed at mitigating stormwater discharges to waterbodies through targeted upgrades to stormwater systems and installations of stormwater BMPs. The purpose of the BMP work is to improve water quality within the Connecticut River Watershed. The BMP work will include construction of vegetated water quality swales and infiltration and exfiltrating bioinfiltration basins. The construction of the proposed stormwater BMPs will provide treatment of stormwater and attenuate flows prior to discharging to the Connecticut River. The nearby river segment that this area drains to (MA34-05 of the Connecticut River) is currently impaired for Escherichia coli, PCB in fish tissue, and total suspended solids (TSS). It has been determined that direct discharge of untreated stormwater from MassDOT roadways contributes to the impairment of this river segment. The capture and treatment of this stormwater will have the same efficacy as removing a portion of the impervious surface contributing stormwater to the project area. The construction of the proposed stormwater BMPs will provide treatment of stormwater and attenuate flows prior to discharging to the Connecticut River. The proposed stormwater BMPs located within Chicopee are in the vicinity of I-391, on the east side of the Connecticut River. Additional BMPs and /or resurfacing are planned for Holyoke, West Springfield, and Agawam.

Project component exemptions and additional jurisdictional details are discussed further below.
