The Nickel Report

On January 22, 2020, the Texas Senate Committees on Natural Resources and Economic Development and Water and Rural Affairs (Senate Committees) held a joint hearing to consider Lt. Governor Dan Patrick’s 2019 interim legislative charge related to one of the most pressing matters facing the state—future water supply issues. This interim charge requires that these legislative committees make recommendations to promote the state’s water supply, including the development of new sources. The recommendations made will be the subject of consideration when the Texas Legislature reconvenes in 2021 and will inform future legislative initiatives. While a broad range of water supply topics was discussed during the hearing, notably, the subject of produced water, including opportunities for reuse within and outside the oil field, continues to be a focal point under review by state policymakers.

Under the Clean Water Act’s National Pollutant Discharge Elimination System (NPDES) and California’s Porter-Cologne Water Quality Control Act, industrial facilities in California are required to obtain coverage under the state’s NPDES general permit for discharges associated with industrial storm water activities (General Industrial Permit) or justify why they are exempt. For regulated facilities, including manufacturing facilities, landfills, mining operations, steam electric power generating facilities, hazardous waste facilities, and oil and gas facilities, failure to obtain coverage under the General Industrial Permit is a potential violation of the Clean Water Act (in addition to state law), which could expose the owner or operator of the facility to potential civil penalties of up to $54,833 per day. Enforcement, however, largely is dependent upon agency inspections or enforcement by citizen groups. Based on estimates by the California Coastkeeper Alliance, many facilities in California may have failed to enroll in the industrial storm water permit program.

The Texas Commission on Environmental Quality (TCEQ) is moving forward with steps necessary to seek delegation of the federal National Pollutant Discharge Elimination System (NPDES) permitting program for produced water discharges. In doing so, Texas will be joining similar efforts underway or under consideration in the neighboring states of Oklahoma and New Mexico. Should EPA delegate such NPDES authority and separately take action to address the restrictive federal regulatory framework now in effect for onshore produced water discharges, this would result in streamlined and expanded beneficial reuse options for produced water in the key oil and gas producing states in the country.

A new decision curtails agency discretion to approve total maximum daily loads for impaired waterbodies and sets a precedent that may lead to more stringent National Pollution Discharge Elimination System (NPDES) permit limits.

Total maximum daily loads (TMDLs) have been described as “pollution budgets” for impaired waterbodies. A permitting authority developing a TMDL typically considers all known sources of the pollutant at issue (including contributions from point and non-point sources) as well as the relevant characteristics of the waterbody (such as flow rates) and determines how much pollutant the waterbody can receive without exceeding applicable water quality standards. Once a TMDL is adopted for a specific pollutant that is adversely affecting a waterbody, the permitting authority (either a delegated state or EPA) will use the TMDL to derive NPDES permit limits for facilities that are sources of the pollutant.

On May 15, 2019, EPA released its draft Study of Oil and Gas Extraction Wastewater Management under the Clean Water Act (Draft Study). The Draft Study addresses the results of an extensive review initiated last year to evaluate the management of oil and gas wastewaters generated at onshore facilities and to assess the need for additional discharge options for onshore oil and gas wastewater under the Clean Water Act (CWA).^[1] Although EPA has not yet adopted any recommendations for regulatory action, it is evident that EPA is continuing to take a hard look at the merits of authorizing broader discharges of produced water to surface waters than those currently allowed for onshore discharges under the CWA effluent guidelines (and generally referred to as the zero discharge standard).^[2] See 40 CFR Part 435, Subpart C. EPA is now requesting additional public comment on the Draft Study by July 1 of this year with the goal of finalizing it and determining next steps this summer.
