Status message

There is 1 rule appearing in the Federal Register for 40 CFR 125. View below or at eCFR (GPOAccess)
§ 125.91 What is a “Phase II Existing Facility”?
(a) An existing facility, as defined in § 125.93, is a Phase II existing facility subject to this subpart if it meets each of the following criteria:
(1) It is a point source.
(2) It uses or proposes to use cooling water intake structures with a total design intake flow of 50 million gallons per day (MGD) or more to withdraw cooling water from waters of the United States;
(3) As its primary activity, the facility both generates and transmits electric power, or generates electric power but sells it to another entity for transmission; and
(4) It uses at least 25 percent of water withdrawn exclusively for cooling purposes, measured on an average annual basis.
(b) In the case of a Phase II existing facility that is co-located with a manufacturing facility, only that portion of the combined cooling water intake flow that is used by the Phase II facility to generate electricity for sale to another entity will be considered for purposes of determining whether the 50 MGD and 25 percent criteria in paragraphs (a)(2) and (4) of this section have been exceeded.
(c) Use of a cooling water intake structure includes obtaining cooling water by any sort of contract or arrangement with one or more independent suppliers of cooling water if the supplier withdraws water from waters of the United States but is not itself a Phase II existing facility, except as provided in paragraph (d) of this section. This provision is intended to prevent circumvention of these requirements by creating arrangements to receive cooling water from an entity that is not itself a Phase II existing facility.
(d) Notwithstanding paragraph (c) of this section, obtaining cooling water from a public water system or using treated effluent as cooling water does not constitute use of a cooling water intake structure for purposes of this subpart.
