— National Emission Standards for Hazardous Air Pollutants From Oil and Natural Gas Production Facilities § 63.760 Applicability and designation of affected source. (a) This subpart applies to the owners and operators of the emission points, specified in paragraph (b) of this section that are located at oil and natural gas production facilities that meet the specified criteria in paragraphs (a)(1) and either (a)(2) or (a)(3) o f this section. (1) Facilities that are major or area sources of hazardous air pollutants (HAP) as defined in §63.761
. Emissions for major source determination purposes can be estimated using the maximum natural gas or hydrocarbon liquid throughput, as a ppropriate, calculated in paragraphs (a)(1)(i) through (iii) of this section. As an alternative to calculating the maximum natural gas or hydrocarbon liquid throughput, the owner or operator of a new or existing source may use the facility's design maximum natural gas or hydrocarbon liquid throughput to estimate the maximum potential emissions. Other means to determine the facility's major source status are allowed, provided the information is documented and recorded to the Administrator's satisfaction in a ccordance with § 63.10(b)(3)
. A facility that is determined to be an area source, but subsequently increases its emissions or its potential to emit above the major source levels (without first obtaining and complying with otherProposed Subpart HH Redline/Strikeout July 28, 2011

Page 2 of ??? limitations that keep its po tential to emit HAP below major source levels) , and becomes a major source, must comply thereafter with all provisions of this subpart applicable to a major source starting on the applicable compliance date specified in paragraph (f) of this section
. Noth ing in this paragraph is intended to preclude a source from limiting its potential to emit through other appropriate mechanisms that may be available through the permitting authority. (i) If the owner or operator documents, to the Administrator's satisfac tion, a decline in annual natural gas or hydrocarbon liquid throughput, as appropriate, each year for the 5 years prior to June 17, 1999, the owner or operator shall calculate the maximum natural gas or hydrocarbon liquid throughput used to determine maxim um potential emissions according to the requirements specified in paragraph (a)(1)(i)(A) of this section
. In all other circumstances, the owner or operator shall calculate the maximum throughput used to determine whether a facility is a major source in ac cordance with the requirements specified in paragraph (a)(1)(i)(B) of this section. (A) The maximum natural gas or hydrocarbon liquid throughput is the average of the annual natural gas or hydrocarbon liquid throughput for the 3 years prior to June 17, 19 99, multiplied by a factor of 1.2.Proposed Subpart HH Redline/Strikeout July 28, 2011

Page 3 of ??? (B) The maximum natural gas or hydrocarbon liquid throughput is the highest annual natural gas or hydrocarbon liquid throughput over the 5 years prior to June 17, 1999, multiplied by a factor of 1.2. (ii) The owner or o perator shall maintain records of the annual facility natural gas or hydrocarbon liquid throughput each year and upon request submit such records to the Administrator
. If the facility annual natural gas or hydrocarbon liquid throughput increases above the maximum natural gas or hydrocarbon liquid throughput calculated in paragraph (a)(1)(i)(A) or (a)(1)(i)(B) of this section, the maximum natural gas or hydrocarbon liquid throughput must be recalculated using the higher throughput multiplied by a factor of 1.2. (iii) The owner or operator shall determine the maximum values for other parameters used to calculate emissions as the maximum for the period over which the maximum natural gas or hydrocarbon liquid throughput is determined in accordance with
paragra ph (a)(1)(i)(A) or (B) of this section
. Parameters shall be based on either highest measured values or annual average. For estimating maximum potential emissions from glycol dehydration units, the glycol circulation rate used in the calculation shall be the unit’s maximum rate under its physicalProposed Subpart HH Redline/Strikeout July 28, 2011

. If no natural gas processing plan t is present, natural gas enters the natural gas transmission and storage source category after the point of custody transfer. (b) The affected sources for major sources are listed in paragraph (b)(1) of this section and for area sources in paragraph (b)( 2) of this section.
