Final Technical Guidance:
DEP ID: 383-2129-002 Title: Guidance for Evaluating Alternate Recycle Return Locations Proposed under the Filter Backwash Recycling Rule. Description: The Interim Enhanced Surface Water Treatment Rule and the Long Term 1 Enhanced Surface Water Treatment Rule require all systems utilizing surface water or groundwater under the direct influence of surface water to achieve at least 2-log removal of Cryptosporidium. To insure that the practice of recycling does not adversely affect the ability of a plant to meet this requirement, the Filter Backwash Recycling Rule (FBRR) requires that certain recycle flows in conventional and direct filtration facilities be returned to a location in the plant so the recycle flow passes through all of the treatment processes by June 8, 2004. The FBRR also allows the return of recycle flows to a location other than the head of the plant if the Department determines that use of the alternate location will not adversely affect the ability of the plant to achieve 2-log Cryptosporidium removal. This guidance was developed to aid permitting staff in evaluating requests to recycle to alternate locations and was issued as Interim Final Guidance at 34 Pa.B. 2890 (May 29, 2004) with provision for a 30-day public comment period, which concluded on June 28, 2004. The Department did not receive any comments on the Interim Final Guidance. The Final Guidance will apply to public water systems that utilize conventional or direct filtration and desire to recycle spent filter backwash, thickener supernatant or liquids from dewatering processes to a location other than the head of the plant. Effective Date: November 27, 2004.
