DEP Provides Clarification On Reporting Requirements For New And Increased POTW Discharges

In 2010 the EQB enacted extensive changes to DEP’s NPDES regulations, now codified at Chapter 92a. Among these changes was a revision to a previous requirement to apply for a new NPDES permit whenever significant changes to influent pollutant loadings-—either the addition of a new pollutant or a substantial increase in an existing pollutant-—was projected to occur. The new regulation, now at § 92a.24(a), is a bit less stringent.

NPDES Permit Basics

Part Four of Four
This is the last in a series of four articles about NPDES permits for Publicly-owned Treatment Works (POTWs). The first three articles in this series discussed Technology-based limits-—TBELs-—and Water quality-based effluent limits-—WQBELs-— in both numerical and narrative form. This article discusses what may be the most important aspect of Permits as they apply to Certified Operators: reporting. Because the reporting rules are so complicated, and because some NPDES permit provisions conflict with the regulations, this article cannot prescribe what to do in all situations. Attempts to obtain clarification from DEP have not been successful, although at the time of writing (fall, 2017) we have received some preliminary and informal comments that might result in revision of this article if they are affirmed by DEP administrative staff.

Dealing with Environmental Agencies

Farming often involves tilling soil and other activities that change the surface of the land. In addition, farm operations can involve the storage and use of liquid fuels and fertilizers. All of these activities potentially involve state and federal environmental laws such as the Pennsylvania Clean Streams Law and Solid Waste Management Act.

NPDES Technology Based Effluent Limits

This is the third article in this 4-part series: [1] about NPDES permits for wastewater discharges from Publicly-Owned Treatment Works (POTWs). All POTWs are required by regulation to give a copy of the current NPDES Permit to all of their Certified Operators. Certified operators, in turn, are required by regulation to know what the Permit requirements are and report to the Owner when a violation is-—or is likely to-—occur. Hence, all Certified Operators should become familiar with the provisions of their permits. Because it is the most complex topic, we discuss effluent limits in the first three installments. The fourth article will explore reporting requirements.

NPDES Water Quality Based Effluent Limits

In the first article in this 4-part series, we discussed “Technology-Based” Effluent Limits, or TBELs, for C-BOD, TSS, pH, fecal coliform bacteria, residual chlorine, and oil and grease. These limits are set by regulation and apply to all POTW discharges regardless of whether or not they are necessary to protect water quality.

NPDES Technology Based Effluent Limits

Part One of Four
This is the first in a series of four articles [1] about NPDES permits for wastewater discharges from Publicly-Owned Treatment Works (POTWs). All POTWs are required by regulation to give a copy of the current NPDES Permit to all of their Certified Operators.

New Total Dissolved Solids Requirements for Publicly Owned Treatment Works

An article on DEP’s revised Chapter 95 regulations that address the acceptance of high-TDS wastes for publicly owned treatment works.

DEP Takes Another Regulatory Step Toward “Discharge Elimination”

Attorney Randall Hurst discusses the new Chapter 92A discharge elimination standards, what they mean, what he anticipates to be some of the problems, and potential solutions to those problems.

The Official Record – a Little Used Tool for Understanding and Interpreting Regulations

As regulated entities (water, solid waste, and wastewater authorities) we are subject to a multitude of “official” documents.
