National Emission Standards for Hazardous Air Pollutants for

Source Categories: Organic Hazardous Air Pollutants From the Synthetic

Organic Chemical Manufacturing Industry and Other Processes Subject to

the Negotiated Regulation for Equipment Leaks; Correction

AGENCY: Environmental Protection Agency (EPA).

ACTION: Correcting amendments.

-----------------------------------------------------------------------

SUMMARY: This action corrects errors and clarifies regulatory text of

the ``National Emission Standards for Hazardous Air Pollutants for

Source Categories: Organic Hazardous Air Pollutants from the Synthetic

Organic Chemical Manufacturing Industry and Other Processes Subject to

the Negotiated Regulation for Equipment Leaks,'' which was issued as a

final rule on April 22, 1994 and June 6, 1994. This rule is commonly

known as the Hazardous Organic NESHAP or the HON.

EFFECTIVE DATE: September 20, 1994.

FOR FURTHER INFORMATION CONTACT: Dr. Janet S. Meyer, Standards

Development Branch, Emission Standards Division (MD-13), U.S.

Environmental Protection Agency, Research Triangle Park, North Carolina

27711, telephone number (919) 541-5254.

SUPPLEMENTARY INFORMATION: On April 22, 1994 (59 FR 19402), and June 6,

1994 (59 FR 29196), the Environmental Protection Agency (EPA)

promulgated in the Federal Register national emission standards for

hazardous air pollutants (NESHAP) for the synthetic organic chemical

manufacturing industry, and for several other processes subject to the

equipment leaks portion of the rule. These regulations were promulgated

as subparts F, G, H, and I in 40 CFR part 63, and are commonly referred

to as the hazardous organic NESHAP, or the HON. This document contains

corrections to typographical and cross-referencing errors in subparts

F, H, and I of the final regulations. A few editorial corrections are

also being made to clarify the intent of certain provisions in these

subparts.

Paragraph (e) of Sec. 63.103 of subpart F is being revised to

clarify that the source owner or operator is required to only document

the basis for the determination that the provisions of the HON do not

apply, and not to keep ongoing records. Tables 1 and 2 of subpart F are

revised to correct typographical errors in spelling of several chemical

names or the chemical abstracts services (CAS) numbers. Thiocarbanilide

is being removed from table 1 of subpart F because this chemical is

listed elsewhere in table 1 as diphenyl thiourea.

A few editorial changes are being made to several sections in

subpart H to clarify the intent of the provisions. Section 63.163(f) is

being revised to remove a requirement to inspect sealless pumps for

indications of liquids dripping from the pump seal. Since this

inspection will not serve the purpose of detecting failures of these

pumps, the requirement to perform these inspections is being removed.

The provisions of Sec. 63.180(b)(2) are being clarified by adding a

sentence explaining that inert gases are not to be considered in

evaluation of instrument response factor.

A number of corrections are being made to subpart I to improve

consistency in terminology and to clarify the provisions. This document

corrects subpart I to use the term ``pharmaceutical production

process'' in Sec. 63.190(b)(5) and in the definitions section. The

definition of ``pharmaceutical production process'' is being clarified

to reflect the intent of the regulatory negotiation committee.

Editorial corrections are being made to Sec. 63.190(e) and

Sec. 63.192(e) to correct a drafting error in usage of the term

``source.'' Several errors in cross referencing subpart A of part 63

and other cross referencing errors are being corrected.

connectors in the process unit was 0.5 percent or greater during the

last required annual or biennial monitoring period.

(ii) Once every 2 years, if the percent leaking connectors was less

than 0.5 percent during the last required monitoring period. * * *

* * * * *

(f) * * *

(2) The owner or operator has a written plan that requires

monitoring of the connector as frequently as practicable during safe to

monitor periods, but not more frequently than the periodic schedule

otherwise applicable.

stream response factor may be calculated on an inert-free basis. The

response factor may be determined at any concentration for which

monitoring for leaks will be conducted.

* * * * *

(c) When equipment is monitored for compliance as required in

Secs. 63.164(i), 63.165(a), and 63.172(f) of this subpart or when
