BACKGROUND

– According to the BCAQMD Staff Report associated with the 2014

rule revision, “The District’s definitions rule currently in the SIP is Rule 102 which was

adopted in 1985 and accepted into the SIP in February, 1987 (52 FR 3226)

. ” 1 “ The

District also recodified the Definitions rule and renumbered it from Rule 102 to Rule 101.

Since many District rules in the SIP rely on these definitions, the District is proposing to

amend this rule to organ ize and update the definitions.” 2

RULE SUMMARY

inclusion of the current “ Exempted VOCs table

, PM2.5, and defining the

“PM2.5 Nonattainment Area” in the BCAQMD

. Many new definitions have been added

, some deleted and a few expanded.

EPA EVALUATION

There will be no effect on air pollution emissions from Rule 101 since the changes

are mostly administrative.4

However, these r evisions improve clarity and enforceability of other BCAQMD

Rules which do reduce emissions.

EPA’s general criteria for rule approval are satisfied by the following:

1. The definitions in Rule 101 are clear and help make other provisions enforceable,

so the rule is consistent with enforceability requirements of the federal Clean Air

Act (CAA) §110(a)(2)(A).

2. Because these definitions do not establish emission controls b ut provide

clarification to requirements found elsewhere, we have determined that they will

not interfere with any applicable requirement concerning attainment and

reasonable further progress (RFP) or any other applicable requirement of the Act

(CAA §110(l )) or modify, in a nonattainment area, any SIP

- approved control

requirement in effect before November 15, 1990 (CAA §193).

3. The rule does not directly establish emission controls, so it is not relevant to

evaluate it regarding stringency.

RECOMMENDED ACTION

EPA staff recommends approval of BCAQMD Rule 101 under CAA §110(k) as meeting

the requirements of CAA §110(a) and Part D

. Approval of BCAQMD Rule 101 would

supersede existing SIP BCAQMD Rules 101 (“Title”) and 102 (“Definitions”), approved at 52

FR 3226 (February 3, 1987), in the applicable California SIP, except for the following

definitions from existing SIP BCAQMD Rule 102: “approved ignition devices,” “open out

- door

fire,” “permissive burn day,” “range improvement burning,” “submerged fill pipe ,” and “vapor

recovery system.” While these terms from existing SIP BCAQMD Rule 102 (“Definitions”) are

no longer included in BCAQMD’s definitions rule (i.e., Rule 101), they are relied upon by

certain existing SIP prohibitory rules, such as existing SIP B CAQMD Rules 213, 215, 302, 313,

317, and 323, and thus must be retained. Approval of the definitions should not be

interpreted as EPA approval of the other rules in which these definitions are used.

ADDITIONAL RECOMMENDATIONS FOR THE NEXT RULE REVISION

- The

following recommendation s are not currently the basis for rule disapproval.

1. The definition, “4.54 Installation” should follow definition, “4.55 Incinerator”

which would correct the alphabetical order.

2. Definition 4.62 cites “Each NESHAP is published as an individual Subpart

to Title 40 Code of Federal Regulations (CFR) Part 60 or 63.” It should be

“ (CFR) Part 61 or 63.”

3. Please correct spelling of the word “earthern” in definition 4.1 to “earthen.”

4. Please correct spelling of the word “aveage” in defin ition 4.9 to “average.”

5. Please correct spelling of the word “Volative” in definition 4.83 to “Volatile.”5

6. Please correct spelling of the word “commbustible” in definition 4.89 to

“combustible.”

7. Please correct spelling of the word “signifcantly” in definitio n 4.107 to

“significantly.”

8. Please correct spelling of the word “compentent” in section 5 to

“competent.”
