The New Source Performance Standards
(NSPS) for Sulfuric Acid Plants (40 CFR Part 60 Subpart H) apply to
both existing facilities and new facilities. New facilities include
those that commenced construction, modification or reconstruction
after the date of proposal. A sulfuric acid plant is any facility
producing sulfuric acid (H2SO4) by the contact process by burning
elemental sulfur, alkylation acid, hydrogen sulfide, organic
sulfides and mercaptans, or acid sludge. A sulfuric acid plant does
not include facilities where conversion to sulfuric acid is used
primarily as a means of preventing emissions to the atmosphere of
sulfur dioxide (SO2) or other sulfur compounds. In general, all
NSPS standards require initial notifications, performance tests,
and periodic reports by the owners/operators of the affected
facilities. They are also required to maintain records of the
occurrence and duration of any startup, shutdown, or malfunction in
the operation of an affected facility, or any period during which
the monitoring system is inoperative. These notifications, reports,
and records are essential in determining compliance, and are
required of all affected facilities subject to NSPS.
The increase in burden from the
most recently-approved ICR is due to an adjustment. Hours were
added to approximate the time spent by each source to familiarize
with the rule requirements, and the total hours were rounded to
three significant digits, which resulted in a small increase in
labor hours and O&M costs since the last renewal.
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).

covers:
(i) Why the information is being collected;
