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 109,327
labor hours at a cost of $10,258,245.

This is a new ICR, so the
associated burden is reflected as an increase due to changing
regulations. However, the NSPS subparts KKK and LLL that are being
revised currently have an approved ICR OMB No. 2060-0120. The
effect of the rulemaking is to reduce the burden for these
subparts. The change in burden refelcts a reduction in the number
of affected facilties reporting under subpart KKK and subpart LLL.
New affected facilties will report under subpart OOOO. The burden
under this ICR will be transferred to 2060-0120 when the rule is
finalized.
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.
