Note to: EPA Negotitated Rulemaking Committee on Equipment Leaks 

Re: Discussion Items for 8/23 Drafting and Gap Closing Session 

Attached is a list of topics that have been identified for discussion in 

the 8/23 meeting. We would like to have the discussion on these areas 

concluded in a brief time (say 1 to 2 hours), so we can devote the bulk of our 

time to working on the regulation. 

Also attached is a revised draft of the equipment leak rule. As before, 

we have followed the organization of the benzene equipment leaks rule (Subpart 

J/V of Part 61) and have shown new material as llllfflf text and the replaced 

provisions as strike out text. This draft represents""our most current version 

of the rule, and it supercedes all previous drafts of the regulation. Work 

still remains on areas related to the discussion points, on the recordkeeping 

and reporting sections, and the cross references among the various sections of 

the rule.

Draft 8/16/90 

(a) Permission to use an alternative means of emission limitation under 

section 112(e)(3) of the Clean Air Act shall be governed by the following 

procedures: 

(b) Where the standard is an equipment, design, or operational 

requirement: 

(1) Each owner or operator applying for permission shall be responsible 

for collecting and verifying test data for an alternative means of emission 

limitation. 

(2) The Administrator will compare test data for the means of emission 

limitation to test data for the equipment, design, and operational 

requirements. 

(3) The Administrator may condition the permission on requirements that 

may be necessary to assure operation and maintenance to achieve the. same ..._. .. 

emission reduction as the equipment, design, and operational requirements. 

(c) Where the standard is a work practice: 

(1) Each owner or operator applying for permission shall be responsible 

for collecting and verifying test data for an alternative means of emission 

limitation. 

(2) For each source for which permission is requested, the emission 

reduction achieved by the required work practices shall be demonstrated for a 

minimum period of 12 months. 

(3) For each source for which permission is requested, the emission 

reduction achieved by the alternative means of emission limitation shall be 

demonstrated. 

44 
Draft 8/16/90 

(4) Each owner or operator applying for permission shall commit, in 

writing, for each source to work practices that provide for emission 

reductions equal to or greater than the emission reductions achieved by the 

required work practices. 

(5) The Administrator will compare the demonstrated emission reduction 

for the alternative means of emission limitation to the demonstrated emission 

reduction for the required work practices and will consider the commitment in 

paragraph (c)(4). 

(6) The Administrator may condition the permission on requirements that 

may be necessary to assure operation and maintenance to achieve the same 

emission reduction as the required work practices of this subpart. 

(d) An owner or operator may offer a unique approach to demonstrate the 

alternative means of emission limitation. 

(e)(1) Manufacturers of equipment used to control equipment leaks of a 

VHAP may apply to the Administrator for permission for an alternative means of 

emission limitation that achieves a reduction in emissions of the VHAP 

achieved by the equipment, design, and operational requirements of this 

subpart. 

(2) The Administrator will grant permission according to the provisions 

of paragraphs (b), (c), and (d).
