SEQR Lead Agency Coordination Response Olivet Center 4 October 28, 2015 Page 3 recommends that the above noted plans, with wetland boundary validation until April 18, 2017, be used as base maps for design of the current proposal. 4. State Pollutant Discharge Elimination System (Article 17) - A. Sanitary Discharge: For the proposed surface discharge of 209,900 gallons per day (gpd) of sanitary wastewater from the existing wastewater treatment system (Phase I discharge 42,345 gpd). As the current SPDES permit for the facility (SPDES# NY 003 2158) approves discharge of 1.2 million gallons per day (MGD), the SPDES permit must be modified to reflect reduced discharge flow. In addition, the current SPDES permit was issued to the previous project sponsor, Dover Knolls Development Co. II, LLC:_ The facility's current SPDES permit should be transferred to Olivet Management, LLC, as the current responsible party. B. Stormwater: Stormwater discharges resulting from construction activities that disturb one or more acres must comply with the current SPDES Stormwater General Permit (Stormwater Discharges from Construction Activities, GP -0-15-002). As the circulated EAF indicates, the action will disturb a total of approximately 60 acres (Phase I will disturb 13 acres), a Stormwater Pollution Prevention Plan (SWPPP) must be prepared which conforms to requirements of the General Permit. 5. Water (duality Certification — The outlet stream from the reservoir is a Class C tributary of the Swamp River and is regulated by the Army Corps of Engineers as a federal wetland. The circulated Phasing Plan shows this outlet stream disappearing under or being covered by a new proposed structure with parking area located on Portchester Way. Please be aware that the Department strongly urges the prosect sponsor to redesign this portion of the proposal so as not to fill, enclose, channelize, realign or otherwise disturb federal wetland areas so as to be more fully protective of these resources. Regardless, as the current proposal includes filling and/or relocating federal wetlands on the site, the project sponsor should contact the US Army Corps of Engineers in New York City (telephone: (917) 790-8411), for any permitting the Corps may require. If a federal permit is required, then a Water Quality Certification (WQC) from the DEC will also be required for any proposed excavation or fill within federally regulated wetland areas. 6. Threatened/Endangered Species (Article 11) — Indiana bat: According to records maintained by the NYS Natural Heritage Program, the project site contains a known occurrence of the Indiana bat, a NYS listed species (NYS Endangered). Specifically, -an Indiana bat bachelor colony is located, on site, in an upland area of the site which is proposed for development ("picnic area" and storage shed). The project site is entirely within 2.5 miles of the known occurrences of Indiana Bat and is considered occupied habitat. The current proposal would apparently clear, or otherwise disturb, this Indiana bat bachelor colony and associated habitat. As a result, Indiana bat roosting and foraging habitat may be adversely affected or lost. The Department strongly recommends that the project be redesigned so as not to disturb, clear or otherwise degrade upland
