PART 1TEXAS COMMISSION ON ENVIRONMENTAL QUALITY
CHAPTER 7MEMORANDA OF UNDERSTANDING
RULE §7.117Memorandum of Understanding between the Railroad Commission of Texas (RRC) and the Texas Commission on Environmental Quality (TCEQ)

    (A) The TCEQ has jurisdiction over wastes generated at facilities, other than actual exploration, development, or production sites (field sites), where oil and gas industry workers are trained. In addition, the TCEQ has jurisdiction over wastes generated at facilities where materials, processes, and equipment associated with oil and gas industry operations are researched, developed, designed, and manufactured. However, wastes generated from tests of materials, processes, and equipment at field sites are under the jurisdiction of the RRC.

    (B) The TCEQ also has jurisdiction over waste generated at commercial service company facilities operated by persons providing equipment, materials, or services (such as drilling and work over rig rental and tank rental; equipment repair; drilling fluid supply; and acidizing, fracturing, and cementing services) to the oil and gas industry. These wastes include the following wastes when they are generated at commercial service company facilities: empty sacks, containers, and drums; drum, tank, and truck rinsate; sandblast media; painting wastes; spent solvents; spilled chemicals; waste motor oil; and unused fracturing and acidizing fluids.

    (C) The term "commercial service company facility" does not include a station facility such as a warehouse, pipeyard, or equipment storage facility belonging to an oil and gas operator and used solely for the support of that operator's own activities associated with the exploration, development, or production activities.

    (D) Notwithstanding subparagraphs (A) - (C) of this paragraph, the RRC has jurisdiction over disposal of oil and gas wastes, such as waste drilling fluids and NORM-contaminated pipe scale, in volumes greater than the incidental volumes usually received at such facilities, that are managed at commercial service company facilities.

    (E) The RRC also has jurisdiction over wastes such as vacuum truck rinsate and tank rinsate generated at facilities operated by oil and gas waste haulers permitted by the RRC pursuant to 16 TAC §3.8(f) (relating to Water Protection).

  (12) Mobile offshore drilling units (MODUs). MODUs are vessels capable of engaging in drilling operations for exploring or exploiting subsea oil, gas, or mineral resources.

    (A) The RRC and, where applicable, the EPA, the U.S. Coast Guard, or the Texas General Land Office (GLO), have jurisdiction over discharges from an MODU when the unit is being used in connection with activities associated with the exploration, development, or production of oil or gas or geothermal resources, except that upon delegation to the TCEQ of NPDES authority for discharges into surface water in the state of produced water, hydrostatic test water, and gas plant effluent resulting from the activities described in Texas Water Code, §26.131(a), the TCEQ shall assume RRC's authority under this subsection.

    (B) The TCEQ and, where applicable, the EPA, the U.S. Coast Guard, or the GLO, have jurisdiction over discharges from an MODU when the unit is being serviced at a maintenance facility.

    (C) Where applicable, the EPA, the U.S. Coast Guard, or the GLO has jurisdiction over discharges from an MODU during transportation from shore to exploration, development or production site, transportation between sites, and transportation to a maintenance facility.

(e) Interagency activities.

  (1) Recycling and pollution prevention.

    (A) The TCEQ and the RRC encourage generators to eliminate pollution at the source and recycle whenever possible to avoid disposal of wastes. Questions regarding source reduction and recycling may be directed to the TCEQ External Relations Division, or to the RRC. The TCEQ may require generators to explore source reduction and recycling alternatives prior to authorizing disposal of any waste under the jurisdiction of the RRC at a facility regulated by the TCEQ; similarly, the RRC may explore source reduction and recycling alternatives prior to authorizing disposal of any waste under the jurisdiction of the TCEQ at a facility regulated by the RRC.

    (B) The TCEQ External Relations Division and the RRC will coordinate as necessary to maintain a working relationship to enhance the efforts to share information and use resources more efficiently. The TCEQ External Relations Division will make the proper TCEQ personnel aware of the services offered by the RRC, share information with the RRC to maximize services to oil and gas operators, and advise oil and gas operators of RRC services. The RRC will make the proper RRC personnel aware of the services offered by the TCEQ External Relations Division, share information with the TCEQ External Relations Division to maximize services to industrial operators, and advise industrial operators of the TCEQ External Relations Division services.

  (2) Treatment of wastes under RRC jurisdiction at facilities authorized by the TCEQ under Chapter 334, Subchapter K of this title (relating to Storage, Treatment, and Reuse Procedures for Petroleum-Substance Contaminated Soil).

    (A) Soils contaminated with constituents that are physically and chemically similar to those normally found in soils at leaking underground petroleum storage tanks from generators under the jurisdiction of the RRC are eligible for treatment at TCEQ regulated soil treatment facilities once alternatives for recycling and source reduction have been explored. For the purpose of this provision, soils containing petroleum substance(s) as defined in §334.481 of this title (relating to Definitions) are considered to be similar, but drilling muds, acids, or other chemicals used in oil and gas activities are not considered similar. Generators under the jurisdiction of the RRC must meet the same requirements as generators under the jurisdiction of the TCEQ when sending their petroleum contaminated soils to soil treatment facilities under TCEQ jurisdiction. Those requirements are in §334.496 of this title (relating to Shipping Procedures Applicable to Generators of Petroleum-Substance Waste), except subsection (c) of this section which is not applicable, and §334.497 of this title (relating to Recordkeeping and Reporting Procedures Applicable to Generators). RRC generators with questions on these requirements should contact the TCEQ.

    (B) Generators under RRC jurisdiction should also be aware that TCEQ regulated soil treatment facilities are required by §334.499 of this title (relating to Shipping Requirements Applicable to Owners or Operators of Storage, Treatment, or Disposal Facilities) to maintain documentation on the soil sampling and analytical methods, chain-of-custody, and all analytical results for the soil received at the facility and transported off-site or reused on-site.

    (C) The RRC must specifically authorize management of contaminated soils under its jurisdiction at facilities authorized by the TCEQ under Chapter 334, Subchapter K of this title (relating to Storage, Treatment, and Reuse Procedures for Petroleum-Substance Contaminated Soil). The RRC may grant such authorizations by rule, or on an individual basis through permits or other written authorizations.

    (D) All waste, including treated waste, subject to the jurisdiction of the RRC and managed at facilities authorized by the TCEQ under Chapter 334, Subchapter K of this title will remain subject to the jurisdiction of the RRC. Such materials will be subject to RRC regulations regarding final reuse, recycling, or disposal.

    (E) TCEQ waste codes and registration numbers are not required for management of wastes under the jurisdiction of the RRC at facilities authorized by the TCEQ under Chapter 334, Subchapter K of this title.

  (3) Processing, treatment, and disposal of wastes under RRC jurisdiction at facilities authorized by the TCEQ.

    (A) As provided in this paragraph, waste materials subject to the jurisdiction of the RRC may be managed at solid waste facilities under the jurisdiction of the TCEQ once alternatives for recycling and source reduction have been explored. The RRC must specifically authorize management of wastes under its jurisdiction at facilities regulated by the TCEQ. The RRC may grant such authorizations by rule, or on an individual basis through permits or other written authorizations. In addition, except as provided in subparagraph (B) of this paragraph, the concurrence of the TCEQ is required to manage "special waste" under the jurisdiction of the RRC at a facility regulated by the TCEQ. The TCEQ's concurrence may be subject to specified conditions.

    (B) A facility under the jurisdiction of the TCEQ may accept, without further individual concurrence, waste under the jurisdiction of the RRC if that facility is permitted or otherwise authorized to accept that particular type of waste. The phrase "that type of waste" does not specifically refer to waste under the jurisdiction of the RRC, but rather to the waste's physical and chemical characteristics. Management and disposal of waste under the jurisdiction of the RRC is subject to TCEQ's rules governing both special waste and industrial waste.
