We are in receipt of the peer review comments provided by Horsley Witten Group, Inc. dated February 21, 2024. The following is our response: 1. The Applicant is subject to the requirements of§195-419 B., "Non-Discharge Buffer Zone." §195-4.19 B refers to §195-4.19 C(3)for Prohibited Uses except as allowed by §195-4.19 C (2) which includes (f) "construction of any accessory structure or expansion of any existing structure by less than 25% of the gross floor area if the existing structure exceeds 2,500 square feet. " The existing house at 3,300 sf has a footprint that exceeds 2,500 sf, and the proposed accessory structure (swimming pool at 684 sfl is less than 25% of the gross floor area. No further action required. No comment 2. The Applicant has included erosion controls on the Plan and has shown where the stockpiles will be located during construction. HW recommends that the Applicant include an additional mulch sock or silt fence surrounding the stockpiling area for erosion protection. The permit site plan has been revised to show a silt fence along with a mulch sock along the limit of work.

The Applicant has proposed a construction access around the west and south side of the house. HW recommends that the Applicant include construction matting to limit the tracking of sediment offsite or onto the driveway. A note regarding the use of construction matting was added to the permit site plan. The location of the proposed construction matting is included on the permit site plan as well. 4. The Applicant proposes that the swimming pool be equipped with a non-backwash filtration system. HW recommends that the Applicant include a checklist log that includes inspecting the filtration system as part of the Operations and Maintenance Plan. The Operations & Maintenance Plan (O&M) was revised to discuss the maintenance schedule for the System:30 Mod Media filter being proposed. In addition, a description of the filter and owner's manual is attached to the O&M document. 5. The Applicant has noted in the O&M Plan that when during normal dewatering following storm events, the pool water shall be pumped into the infiltration trench. HW notes that the pool water should be dechlorinated prior to being pumped to the infiltration system. The O&M was revised to discuss dechlorinating the water prior to being pumped to the infiltration system. 6. HW agrees that the infiltration trench surrounding the patio will provide adequate stormwater management for the additional impervious surface. No action required. No comment If you should have any questions regarding this information, or require any additional information,please do not hesitate to contact our office.

A Pentair System 30 Modular Media Filter is proposed (see attached filter description and owner's manual). • The property owner shall engage a water hauling company to pump the water and truck the water offsite anytime the pool needs to be drained. Final disposal of the water by the water hauling company shall be in accordance with all federal and state regulations. • Pool water shall be dechlorinated by not adding chemicals and letting the pool water sit for a minimum of 10 days. At that point,the pool water can be pumped into the proposed infiltration trench system during normal dewatering following storm events. • Pool chemicals shall be properly stored according to manufacturers' labels in an enclosed shed or garage to ensure proper containment of any spills or drips. Pool Filtration System • Pool filtration system to be cleaned and maintained in accordance with manufacturer specifications detailed in the attached owner's manual. • Once operating pressure reaches 10 PSI above initial operating pressure,inspect and clean filter element. Filter element should be cleaned with hose and drained into stone infiltration trench. • On a weekly basis, debris should be removed from skimmer basket. The pump should be stopped,release all pressure,and remove trap cover and basket to remove any additional debris. Air filter should be bled each time system is started. Infiltration Trench This Operations &Maintenance Plan has been prepared to comply with the provisions set forth in the Massachusetts Department of Environmental Protection (DEP) Stormwater Management Standards.

Maintenance schedules found below are recommended in Department of Environmental Protections Massachusetts Stormwater Handbook and as recommended in the manufacturer's specifications. The stormwater management system owner and the party responsible for maintenance of the stormwater management system shall be the property owner and their designated employees. • Inspect and clean every six months and after every major storm event of 0.5 inches in a 24-hour period. • Remove accumulated sediment, trash, debris,leaves and grass clippings. • Remove tree seedlings before they become firmly established. • Inspect the trench 24 hours or several days after a rain event to look for ponded water. If there is ponded water at the surface of the trench,it is likely that the trench surface is clogged. • To address surface clogging,remove and replace the first layer of stone aggregate and filter fabric. If the water is ponded inside the trench, it may indicate that the bottom of the trench has failed. • To rehabilitate a failed trench, all accumulated sediment must be stripped from the bottom, the bottom of the trench must be scarified and tilled to induce infiltration, and all of the stone aggregate and filter fabric or media must be removed and replaced.
