The f inal oil and n atural g as s ector n ew s ource p erformance s tandards w ere published in the
Federal Register on August 16, 2012 (7 7 FR 49490 ). The final rule, which became effective on

October 1 5 , 20 12

, 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 descr ibed in this memorandum do not change the basic requirements of the rule, but

a re intended to improve clarity and ensure accuracy

. The technical corrections are detailed in the
following table

. T he table identif ies the citations and explains the changes to the rule text.

### Table 1. Summary of Revisions Made to 40 CFR Part 60 Subpart OOOO f or the Oil and Natural Gas Sector.



### Section Paragraph Revision Summary

§6 0

. 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

controlle rs 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 identifyi ng 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 r evision 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 na tural gas processing plant or an oil pipeline . The paragraph should have included §60.5390(c)(2).

§60.5415 How do I demonstrate

cont inuous 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, a nd 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.

§60.541 6 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).

(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 fo r 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 §60.54 15(e)(7)(iii) which does not exist. The correct

reference should be §60.541 3 (e)( 3 ).

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 Fi nal 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 compressor s 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 paragr aph 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 §60.539 0(b)(2).
