OMB files this comment in accordance with 5 CFR 1320.11( c ). This OMB action is not an approval to conduct or sponsor an information collection under the Paperwork Reduction Act of 1995. This action has no effect on any current approvals. If OMB has assigned this ICR a new OMB Control Number, the OMB Control Number will not appear in the active inventory. For future submissions of this information collection, reference the OMB Control Number provided. OMB is withholding approval at this time. Prior to publication of the final rule, the agency should provide a summary of any comments related to the information collection and their response, including any changes made to the ICR as a result of comments. In addition, the agency must enter the correct burden estimates. This action has no effect on any current approvals.

The New Source Performance Standards (NSPS) for Onshore Natural Gas Processing Plants, published at 40 CFR part 60, subpart KKK, were proposed on January 20, 1984, and promulgated on June 24, 1985. These standards apply to the following affected facilities located at onshore natural gas processing plants: compressors in equipment leaks of Volatile Organic Compound (VOC) service or in wet gas service, and the groups of all equipment (except compressors) within a process unit. Affected facilities commenced construction, modification, or reconstruction after the date of proposal. A process unit is defined as the equipment assembled for extraction of natural gas liquids from field gas, fractionation of liquids into natural gas products, or other processing of natural gas products. This information is being collected to assure compliance with 40 CFR part 60, subpart KKK.
The New Source Performance Standards (NSPS) for Onshore Natural Gas Processing - SO2 Emissions- (0 CFR part 60, subpart LLL) were proposed on January 20, 1984, and promulgated on October 1, 1985. These standards apply to the following affected facilities located at onshore natural gas processing plants: each sweetening unit, and each sweetening unit followed by a sulfur recovery unit. Affected facilities commenced construction, modification, or reconstruction after the date of proposal. A sweetening unit is defined as a process device that separates the hydrogen sulfide and carbon dioxide (CO2) contents from the sour natural gas stream. The provisions of subpart LLL do not apply to sweetening facilities that produce acid gas that is completely re-injected into oil or gas bearing geologic strata or that is otherwise not released to the atmosphere. The control and monitoring requirements of subpart LLL do not apply to affected facilities with design capacities of less than two long tons per day (LT/D) of hydrogen sulfide in the acid gas, expressed as sulfur. This information is being collected to assure compliance with 40 CFR part 60, subpart LLL.
As part of the mandatory review of NSPS as required under the Clean Air Act, the requirements of both subpart KKK and LLL would be contained in a new subpart, 40 CFR 60, subpart OOOO. Subpart OOOO will supersede subpart KKK and LLL, and the existing provisions of subpart KKK and LLL would be included in the new subpart OOOO . The revisions to this ICR account for the reduction in new sources estimated that will report under KKK and LLL (new sources will now report under the ICR for subpart OOOO). This ICR accounts for the existing burden for sources still reporting under KKK and LLL. We have also updated labor cost estimates and removed all instances of recording and reporting due to start-up, shutdown and malfunction.
All of these sources subject to subpart LLL are also subject to subpart KKK. Over the next three years, an average of 507 sources per year will be subject to subpart KKK and LLL. In general, all NSPS standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. These notifications, reports, and records are essential in determining compliance, and are required of all sources subject to NSPS. Approximately 70 of the 507, are also currently subject to subpart LLL. The annual industry burden estimated for this ICR is 109,266 labor hours at a cost of $10,251,963.
The change in burden results from the development of subpart OOOO, which supersedes both subpart KKK and LLL. Any new or modified affected facility will begin reporting under subpart OOOO instead of subpart KKK and LLL.
On behalf of this Federal agency, I certify that the collection of information encompassed by this request complies with 5 CFR 1320.9 and the related provisions of 5 CFR 1320.8(b)(3).
The following is a summary of the topics, regarding the proposed collection of information, that the certification covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control number;
If you are unable to certify compliance with any of these provisions, identify the item by leaving the box unchecked and explain the reason in the Supporting Statement.
