- National Emission Standards for Hazardous Air Pollutants From Natural Gas Transmission and Storage Facilities § 63.1270 Applicability and designation of affected source. (a) This subpart applies to owners and operators of natural gas transmiss ion and storage facilities that transport or store natural gas prior to entering the pipeline to a local distribution company or to a final end user (if there is no local distribution company), and that are major sources of hazardous air pollutants (HAP) e missions as defined in §63.1271. Emissions for major source determination purposes can be estimated using the maximum natural gas throughput calculated in either paragraph (a)(1) or (2) of this section and paragraphs (a)(3) and (4) of this section. As an a lternative to calculating the maximum natural gas throughput, the owner or operator of a new or existing source may use the facility design maximum natural gas 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 accordance with §63.10(b)(3) . A compressor station that transports natural gas prior to the point of custody transfer or to a natur al gas processing plant (if present) is not considered a part of the natural gas transmission and storage source category. A facility that is determined to be an area source, but subsequentlyProposed Subpart HHH Redline/Strikeout July 28, 2011

Please refer to the CFR for the official version. increases its emissions or its potential to emit above the major source levels (without first obtaining and complying with other limitations that keep its potential to emit HAP below major source levels), and becomes a major source, must comply thereafter with all applicable provisions of this subpart starting on the a pplicable compliance date specified in paragraph (d) of this section. Nothing 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
. (1) Facilities that store natural gas or facilities that transport and store natural gas shall calculate maximum annual facility natural gas throughput using the following equation:

Where : Throughput = Maximum annual facility wide natural gas throughput in cubic meters per year. IR max = Maximum facility injection rate in cubic meters per hour. WR max = Maximum facility withdrawal rate in cubic meters per hour. 8,760 = Maximum hours of opera tion per year. (i)

( 3) The owner or operator shall maintain records of the annual facility natural gas throughput each year and upon request, submit such records to the Administrator. If the facility annual natural gas throughput increases above the maximum natural gas throug hput calculated in paragraph (a)(1) or (a)(2) of this section, the maximum natural gas throughput must be recalculated using the higher throughput multiplied by a factor of 1.2. (4) The owner or operator shall determine the maximum values for other parame ters used to calculate potential emissions as the maximum over the same period for which maximum throughput is determined as specified in paragraph (a)(1) or (a)(2) of this section. These parameters shall be based on an annual average or the highest single measured value. 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 physical and operational design consistent with the definition of pote ntial to emit in §63.2. (b) The affected source is each glycol dehydration unit. (c) The owner or operator of a facility that does not contain an affected source, as specified in paragraph (b) ofProposed Subpart HHH Redline/Strikeout July 28, 2011
