Current through Register Vol. 48, No. 28, July 12, 2024
a)
				Applicability. This Section applies to facilities engaged in the production,
				field exploration, drilling, well completion, and well treatment in the oil and
				gas extraction industry that are not included within subpart F of 40 CFR 435
				(2016) (Stripper Subcategory), incorporated by reference. This incorporation
				includes no later amendments or editions.
BOARD NOTE: Subsection (a) is derived from
				  40 CFR
				  435.30 (2016).
b) Specialized Definitions. For the purpose
				of this Section, the general definitions, abbreviations, and methods of
				analysis set forth in 40 CFR 401 (2016), incorporated by reference, apply to
				this Section. This incorporation includes no later amendments or editions.
BOARD NOTE: Subsection (b) is derived from
				  40 CFR
				  435.31 (2016).
c) Pretreatment Standards for Existing
				Sources (PSES).
1) PSES for Wastewater from
				Unconventional Oil and Gas Extraction.
Except as provided in
				  40 CFR 403.7 and
				  403.13
				  (2016), incorporated by reference, any existing source subject to this Section
				  must achieve the following PSES. This incorporation by reference includes no
				  later amendments or editions.
A) There
				must be no discharge of wastewater pollutants associated with production, field
				exploration, drilling, well completion, or well treatment for unconventional
				oil and gas extraction (including, but not limited to, drilling muds, drill
				cuttings, produced sand, or produced water) into publicly owned treatment
				works.
B) For the purposes of this
				subsection (c) and subsection (d), the following definitions apply:
i) "Unconventional oil and gas" means crude
				oil and natural gas produced by a well drilled into a shale or tight formation
				(including, but not limited to, shale gas, shale oil, tight gas, or tight
				oil).
ii) "Drill cuttings" means
				the particles generated by drilling into subsurface geologic formations and
				carried out from the wellbore with the drilling fluid.
iii) "Drilling mud" means the circulating
				fluid (mud) used in the rotary drilling of wells to clean and condition the
				hole and to counterbalance formation pressure.
iv) "Produced sand" means the slurried
				particles used in hydraulic fracturing, the accumulated formation sands, and
				scale particles generated during production. Produced sand also includes
				desander discharge from the produced water waste stream and blowdown of the
				water phase from the produced water treating system.
v) "Produced water" means the fluid brought
				up from the hydrocarbon-bearing strata during the extraction of oil and gas,
				and includes, where present, formation water, injection water, and any
				chemicals added downhole or during the oil/water separation
				process.
C) Compliance
				Deadline for Existing Sources. Existing sources lawfully discharging into
				publicly owned treatment works on or between April 7, 2015 and June 28, 2016
				must comply with the PSES before August 29, 2019. All other existing sources
				must immediately comply.
BOARD NOTE: Corresponding
				  40 CFR
				  435.33(a)(3) provides, "All
				  other existing sources shall comply by August 29, 2016."
