Final Technical Guidance—New Guidance

 DEP ID: 385-2100-002. Title: Policy and Procedure for National Pollution Discharge Elimination System (NPDES) Permitting of Discharges of Total Dissolved Solids (TDS)—25 Pa. Code § 95.10 (relating to treatment requirements for new and expanding mass loadings of Total Dissolved Solids (TDS)). Description: On August 21, 2010, revisions to 25 Pa. Code § 95.10 became final. These revisions mandated new treatment requirements for discharges of TDS from NPDES point sources of treated wastewater. The provisions of 25 Pa. Code § 95.10 require detailed guidance for NPDES permit writers to implement the new requirements through NPDES permit conditions and actions. This new guidance document fulfills that need. The Department published notice of the draft proposed guidance in the Pennsylvania Bulletin at 41 Pa.B. 560 (January 22, 2011). Public comments were accepted until the comment period closed on February 22, 2011. Twenty-one sets of written comments were received during the public comment period and are summarized in the associated Comment and Response Document. The draft guidance was revised as a result of these comments in order to produce this final guidance document. Contact: Thomas Starosta, (717) 787-4317 or

Effective Date: November 12, 2011.
