MEMORANDUM

SUBJECT: Technical Corrections to the Final Oil and Natural Gas Sector New Source 

Performance Standards 

FROM: Bruce Moore

Sector Policies and Programs Division

Office of Air Quality Planning and Standards

TO: Docket ID No. EPA-HQ-OAR-2010-0505

The final oil and natural gas sector new source performance standards were published in the 

Federal Register on August 16, 2012 (77 FR 49490). The final rule, which became effective on 

October 15, 2012, established standards for certain oil and gas operations not covered by the 

existing standards, including gas wells, centrifugal compressors, reciprocating compressors, 

pneumatic controllers, and storage vessels (40 CFR part 60, subpart OOOO). The technical 

corrections described in this memorandum do not change the basic requirements of the rule, but 

are intended to improve clarity and ensure accuracy. The technical corrections are detailed in the 

following table. The table identifies the citations and explains the changes to the rule text.
Table 1. Summary of Revisions Made to 40 CFR Part 60 Subpart OOOO for the Oil and Natural Gas Sector.

Section Paragraph Revision Summary

§60.5390 What standards apply to 

pneumatic controller affected 

facilities?

Introductory 

paragraph

The introductory text in §60.5390 was revised to clarify the requirement that exempt pneumatic 

controllers at natural gas processing plants and exempt pneumatic controllers between the wellhead 

and natural gas processing plant and between the wellhead and custody transfer to a crude oil 

pipeline must be tagged with identifying information.

(a) Paragraph (a) was revised to clarify requirements for pneumatic controllers with a bleed rate greater 

than the applicable standard and which are required to meet functional needs.

§60.5410 How do I demonstrate 

compliance with the standards for 

my gas well affected facility, my 

reciprocating compressor affected 

facility, my pneumatic controller 

affected facility, my storage vessel 

affected facility, and my equipment 

leaks and sweetening unit affected 

facilities at onshore natural gas 

processing plants?

(b)(8) This revision corrects a typographical error. The citation reference should be §60.5420(c)(2) and 

not §60.5420(c)(3).

(d)(4) This revision corrects an omission of tagging for a pneumatic controller affected facility at a location 

between the wellhead and a natural gas processing plant or an oil pipeline. The paragraph should 

have included §60.5390(c)(2).

§60.5415 How do I demonstrate 

continuous compliance with the 

standards for my gas well affected 

facility, my centrifugal compressor 

affected facility, my stationary 

reciprocating compressor affected 

facility, my pneumatic controller 

affected facility, my storage vessel 

affected facility, and my affected 

facilities at onshore natural gas 

processing plants?

(h)(1) This revision corrects the citation from §60.5420(a) to §60.5415(h)(2) for affirmative defense 

reporting requirements.

§60.5416 What are the initial and 

continuous cover and closed vent 

system inspection and monitoring 

requirements for my storage vessel 

and centrifugal compressor affected 

facility?

Introductory 

paragraph

This revision corrects the paragraph numbering for this section. The paragraph numbering has been 

changed from (a) through (g) to (a) through (c).

(a) This revision corrects the paragraph numbering for this paragraph. The paragraph numbering has 

been changed from (e) and (f) to (b)(11) and (b)(12).
Section Paragraph Revision Summary

(a)(3)(ii) This revision corrects the paragraph numbering for this paragraph. The paragraph numbering has 

been changed from (e) and (f) to (b)(11) and (b)(12).

(b)(9) This revision corrects the paragraph numbering for this paragraph. The paragraph numbering has 

been changed from (d) to (b)(10).

(b)(11) This revision corrects the paragraph numbering for this paragraph. The paragraph numbering has 

been changed from (e)(1) and (2) to (b)(11)(i) and (b)(11)(ii).

(b)(11) This revision corrects the paragraph numbering for this paragraph. The paragraph numbering for the 

subparagraphs should be (i) and (ii) and not (A) and (B).

§60.5417 What are the continuous 

control device monitoring 

requirements for my storage vessel or 

centrifugal compressor affected 

facility?

(a) This revision corrects the paragraph numbering for this section that only includes paragraphs from 

(a) through (g).

(b) This revision corrects the paragraph numbering for this section that only includes paragraphs from 

(a) through (g).

(g)(6)(ii) The revision corrects an incorrect reference to §60.5415(e)(7)(iii) which does not exist. The correct 

reference should be §60.5413(e)(3).

§60.5420 What are my notification, 

reporting, and recordkeeping 

requirements?

(a) This revision clarifies the notification requirements for the affected sources in this rule. The 

clarification removes the notification requirements in §60.7(a)(1) and (4), and requires only the 

notification requirements in subparagraphs (a)(1) through (3) of this section.

This revision is based on language in V.F. of the preamble for the Final Rule that states “For well 

completions, compressors, pneumatic controllers and storage vessels, we have removed the General 

Provisions notification requirements in 40 CFR 60.7(a)(1), (3) and (4).”

(a)(1) This revision includes centrifugal compressors and reciprocating compressors in the list of affected 

sources that do not have to submit the General Provision notifications in §60.7(a)(1), (3), and (4).

This revision is based on language in V.F. of the preamble for the Final Rule that states “For well

completions, compressors, pneumatic controllers and storage vessels, we have removed the General 

Provisions notification requirements in 40 CFR 60.7(a)(1), (3) and (4).”

(b)(5) This revision corrects the paragraph numbering for this section. The paragraph only has three 

subparagraphs and therefore the numbering has been changed from (b)(5)(i) through ((b)(5)(v) to 

(b)(5)(i) through (iii).
Section Paragraph Revision Summary

(b)(5)(i) This revision corrects the omission of reference to pneumatic controllers at natural gas processing 

plants in §60.5390(b)(2).
