Testing and Monitoring
Section 218
Section 218.768 Testing and
Monitoring
a) Compliance with Section 218.762(a)(2) of this Subpart shall be
determined by visual inspection and by the leak detection methods contained in
Section 218.105(g) of this Part.
b) If the control device used to comply with Section
218.762(a)(1) of this Subpart is a flare, compliance shall be determined by
methods described in Section 218.429(c) of this Part.
c) For all other control devices used to comply with Section
218.762(a)(1) of this Subpart, compliance shall be determined by methods
described in Section 218.105(d) and (f) of this Part.
d) Compliance with Section 218.762(b)(3) of this Subpart shall be
determined by one of the methods described in this Section:
1) A marine vessel loaded in accordance with Section
218.762(b)(3)(A) of this Subpart through the use of a vacuum assisted vapor
collection system is assumed to be vapor-tight for the purposes of this
Subpart.
2) A vapor-tightness test for marine vessels shall be conducted
to include the final 20 percent of loading of each product tank of the marine
vessel, and it shall be applied to any potential sources of vapor leaks on the
vessel pursuant to Method 21 of 40 CFR 60, Appendix A, incorporated by
reference at Section 218.112 of this Part. A reading of 10,000 ppmv or greater
as methane shall constitute a leak.
3) As an alternative to subsection (d)(2) of this Section, an
owner or operator of a marine terminal may use the vapor-tightness test
described in 40 CFR 61.304(f), incorporated by reference at Section 218.112 of
this Part.
e) When in the opinion of the Agency or USEPA it is necessary to
conduct testing to demonstrate compliance with or verify effectiveness of the
vapor collection and control system required by Section 218.762(a), (c)(1), or
(c)(3) of this Subpart, the owner or operator of a marine terminal shall, at
its own expense, conduct such tests in accordance with the applicable test
methods and procedures specified in subsections (a), (b), or (c) of this
Section, as applicable.
f) An owner or operator of a marine terminal planning to conduct
a VOM emissions test to demonstrate compliance with Sections 218.762(a),
(c)(1), or (c)(3) of this Subpart shall notify the Agency of that intent not
less than 30 days before the planned initiation of the tests so that the Agency
may observe the test.
