Abstract |
This report has been prepared as a document supporting the rulemaking and promulgation of the final regulation (40 CFR 401.17) modifying existing effluent guideline pH regulations for permittees required or allowed to monitor continuously the pH of their wastewater discharges by National Pollutant Discharge Elimination System (NPDES) permit. The document presents the methodologic approach used in identifying, classifying, summarizing, and assessing the public comments received with respect to this rulemaking. This Task was directed toward the provision of technical, analytical, and statistical support in assisting EPA (1) to identify major issues presented by public commenters, (2) to formulate a final pH regulation, and (3) to produce a document citing the activities and analyses undertaken in formulating the final pH regulation. |
