Subject: State Implementation Plan Submittal, NSAQMD Rule 215

Dear Mr. Guzzetta:

Enclosed is the information necessary for submittal of Rule 215, Phase II Vapor Recovery System Requirements, for revision to the St ate Implementation Plan. The Western Nevada County portion of the Northern Sierra AQMD is non-attainment for the 1997 federal 8-hour ozone standard, but is not yet classified. Rule 215 is part of a series of rules designed to meet federal RACT for vapor recovery. Rule 215 was amended by the District’s Board of Directors on February 22, 2010, following a public hearing, because the previous version submitted to EPA was not fully approvable into the SIP. EPA indicated that the NSAQMD could choose to revise and resubmit the Rule or let EPA publish a “partial approval” in the Federal Register. The NSAQMD chose to revise the Rule to address all of EPA’s concerns.

The previous Rule 215 relied on an ARB executive order that is not approved into the SIP. The rule amendment places ARB executive order material into the rule, along with more complete definitions, better organization, more thorough test method references and reporting requirements, improved enforceability and other administrative improvements.

A draft of amended Rule 215 was submitted to the California Air Resources Board (ARB) on September 16, 2009, and the adopted rule was modified based on ARB’s comments and EPA’s

comments.

Rule 215 references District Rules 214, 401 and 522, which are included.

No workshops were held for the Rule amendment.

The amended rule is so vastly different from the previous rule that Microsoft Word is unable to generate a strikeout-underline version highlighting the changes. Therefore, the original version
is included with this letter rather than a strikeout-underline version.

If you have any comments or questions, pl ease contact me at (530) 274-9360 x106.

Sincerely, Samuel F. Longmire, Air Pollution Control Specialist III
