"Interim Guidance For Performance-Based Reduction of NPDES Permit Monitoring Frequencies."

Interim guidance to reduce unnecessary pollutant-specific monitoring and reporting in reissued NPDES permits with an excellent compliance and enforcement history. Does not advocate reductions for parameters monitored only once per quarter or for limits below analytical level of quantification. April 1995 (25 pgs) EPA 833-B-96-001.

"Final NPDES General Permits for Storm Water Discharges from Construction Sites; Fact Sheet"

This document summarizes the technical, legal and policy considerations used in developing the NPDES general permit for storm water discharges associated with construction activity. September 1992. (33 pgs.) (57 FR 41176) EPA 833/Z-92-002.

"Final NPDES General Permits For Storm Water Discharges Associated With Industrial Activity; Permit Language"

These general permits establish Notice of Intent (NOI) requirements, prohibitions, requirements to develop and implement storm water pollution prevention plans, and requirements to conduct site inspections for facilities with dischargers authorized by the permit. In addition, these general permits establish monitoring requirements for certain classes of facilities and a numeric effluent limitation for discharges of coal pile runoff subject to the general permits.

Guidance and Standards for Calculating Point Source Pollutant Loads Using the Permit Compliance System

PCS is the primary repository of data used to determine reductions in pollutant loads to the waters of the United States. This effort falls under the umbrella of EPA's National Goals Project, which has developed a series of milestones for measuring improvements to the waters ofthe United States over the next 10 years. Measuring point source load reductions using PCS is one way to monitor improvements. The purpose of this guidance is to establish guidelines for consistent coding of NPDES permits in a manner that facilitates load reduction estimation through the use of PCS.
