DOCKET NO. D-2006-020-3 DELAWARE RIVER BASIN COMMISSION Discharge to a Tributary of Special Protection Waters SC Stream PA, LLC - Paradise Stream Resort Wastewater Treatment Plant Paradise Township, Monroe County, Pennsylvania PROCEEDINGS This docket is issued in response to an Application submitted to the Delaware River Basin Commission (DRBC or Commission) by Prosser Laboratories, Inc. on behalf of SC Stream PA, LLC - Paradise Stream Resort, on July 11, 2016 (Application), for renewal of a wastewater treatment plant (WWTP) approval. Draft National Pollutant Discharge Elimination System (NPDES) Permit No. PA0061115 for the discharge was issued by the PADEP on November 30, 2012. The Application was reviewed for approval under Section 3.8 of the Delaware River Basin Compact. The Monroe County Planning Commission has been notified of pending action. A public hearing on this project was held by the DRBC on May 17, 2017. A. DESCRIPTION 1. Purpose. The purpose of this docket is to renew the approval of the docket holder’s existing 0.05 million gallons per day (mgd) SC Stream PA, LLC - Paradise Stream Resort WWTP. 2. Location. The Paradise Stream Resort WWTP is located off PA Route 940 approximately 0.2 miles west of the intersection with PA Route 390, in Paradise Township, Monroe County, Pennsylvania. The WWTP will continue to discharge treated wastewater to Paradise Creek, which is a tributary to the Brodhead Creek at River Mile 213 - 13.7 – 7.7 (Delaware River - Brodhead Creek - Paradise Creek). The WWTP discharge is located in the drainage area to the Middle Delaware Special Protection Waters (SPW) area. The WWTP outfall is located in the Paradise Creek Watershed as follows: OUTFALL NO. LATITUDE (N) LONGITUDE (W) 001 41 ° 07’ 40” 75 ° 18’ 31” D-2006-020-3 (SC Stream PA, LLC - Paradise Stream Resort - WWTP) 2 3. Area Served. The existing WWTP will continue to serve the Paradise Stream Resort. For the purpose of defining the Area Served, sections B (Type of Discharge) and D (Service Area) of the docket holder’s Application are incorporated herein by reference, to the extent consistent with all other conditions contained in the DECISION Section of this docket. 4. Physical Features. a. Design Criteria. The docket holder’s 0.05 mgd WWTP treats domestic sanitary wastewater through an activated sludge treatment process. b. Facilities. The WWTP treatment facilities consist of a 30,000 gallon flow equalization tank, two 25,000 gallon extended aeration tanks, two clarifiers, chlorine disinfection, and a post aeration tank. The docket holder’s wastewater treatment facility discharges to waters classified as SPW and is required to have available emergency power. The Paradise Stream WWTP has a generator installed capable of providing emergency power supply. (SPW) The docket holder’s wastewater treatment facility is not staffed 24 hours per day; however staff is available 24 hours per day at the Paradise Stream Resort. (SPW) The docket holder’s existing wastewater treatment facility has prepared and implemented an emergency management plan (EMP) in accordance with Commission requirements. (SPW) Wasted sludge will continue to be hauled off-site by a licensed hauler for disposal at a state approved facility. The project facilities are not located in the 100-year floodplain. c. Water Withdrawals. The potable water supply in the project service area is provided by an on-site well. The well is operated at a withdrawal rate below the DRBC groundwater review threshold. d. NPDES Permit / DRBC Docket. The PADEP issued draft NPDES Permit No. PA006115 on November 30, 2012, which includes final effluent limitations for the project discharge of 0.1 mgd to surface waters classified by the PADEP as HQ-CWF (High Quality – Cold Water Fishery). NPDES Permit No. PA0061115 was issued by the PADEP on November 30, 2012 (January 1, 2013) and includes final effluent limitations for the project discharge of 0.1 mgd to surface waters classified by the PADEP as HQ-CWF (High Quality – Cold Water Fishery). Note: The WWTP’s hydraulic design capacity is 0.05 mgd; however, the effluent limitations in the NPDES permit were determined using a flow of 0.1 mgd. The PADEP indicated that basing D-2006-020-3 (SC Stream PA, LLC - Paradise Stream Resort - WWTP) 3 the effluent limits on a discharge rate of 0.1 mgd is continued from a previous NPDES permit. The following average monthly effluent limits are among those listed in the NPDES permit and meet or are more stringent than the effluent requirements of the DRBC.

FINDINGS The docket holder submitted an Application to renew the approval of the existing 0.05 mgd Paradise Stream Resort WWTP on July 11, 2016. This docket (D-2006-020-3) renews the DRBC approval. In 1992, the DRBC adopted Special Protection Waters requirements, as part of the DRBC Water Quality Regulations (WQR), designed to protect existing high water quality in applicable areas of the Delaware River Basin. One hundred twenty miles of the Delaware River from Hancock, New York downstream to the Delaware Water Gap has been classified by the DRBC as SPW. This stretch includes the sections of the river federally designated as "Wild and Scenic" in 1978 -- the Upper Delaware Scenic and Recreational River and the Delaware Water Gap National Recreation Area -- as well as an eight-mile reach between Milrift and Milford, Pennsylvania which is not federally designated. The SPW regulations apply to this 120-mile stretch of the river and its drainage area. On July 16, 2008, the DRBC approved amendments to its WQR that provide increased protection for waters that the Commission classifies as SPW. The portion of the Delaware River and its tributaries within the boundary of the Lower Delaware River Management Plan Area was D-2006-020-3 (SC Stream PA, LLC - Paradise Stream Resort - WWTP) 4 approved for SPW designation and clarity on definitions and terms were updated for the entire program. The docket holder’s WWTP discharges to the Middle Delaware River SPW. The docket holder’s WWTP discharge is required to comply with the SPW requirements, as outlined in Article 3.10.3A.2. of the WQR. Article 3.10.3A.2.e.1). and 2). of the Water Quality Regulations, Administrative Manual - Part III, states that projects subject to review under Section 3.8 of the Compact that are located in the drainage area of Special Protection Waters must submit for approval a Non-Point Source Pollution Control Plan that controls the new or increased non-point source loads generated within the portion of the applicant’s service area which is also located within the drainage area of Special Protection Waters. The service area of the docket holder is located within in the drainage area to the Special Protection Waters. Since this project does not entail additional construction and expansion of facilities and/or service area and there are not any new or increased non-point source loads associated with this approval, the non-point source pollution control plan requirement is not applicable at this time. Accordingly, Special Condition C.II.m. has been included in the Decision section of this docket. At the WWTP discharge location, Paradise Creek has an estimated seven-day low flow with a recurrence interval of ten years (Q7-10) of 0.014 mgd (0.022 cfs). The ratio of this low flow to the hydraulic design wastewater discharge from the 0.05 mgd WWTP is 0.28 to 1. The nearest surface water intake of record for public water supply is located on the Brodhead Creek approximately 17 River Miles downstream of the docket holder’s WWTP, and is operated by the Brodhead Creek Regional Authority. The project does not conflict with the Comprehensive Plan and is designed to prevent substantial adverse impact on the water resources related environment, while sustaining the current and future water uses and development of the water resources of the Basin. The limits in the NPDES Permit are in compliance with Commission effluent quality requirements, where applicable. The project is designed to produce a discharge meeting the effluent requirements as set forth in the Water Quality Regulations of the DRBC. C. DECISION I. Effective on the approval date for Docket No. D-2006-020-3 below, Docket No. D-2006-020-2 is terminated and replaced by Docket No. D-2006-020-3.
