Regional Compliance Agreement

Updated 12/13/11

Sacramento Region Tier 1 or 2 Engine Compliance Agreement

The Placer County Air Pollution Control District and two other Sacramento region air districts (Sacramento Metropolitan Air Quality Management District, and Yolo-Solano Air Quality Management District) have worked together to establish a Tier 1 or 2 Regional Compliance Agreement (RCA) that allows Tier 1 or 2 engine owners/operators to have one agreement allowing operation throughout the Sacramento region until January 1, 2017 for Tier 1 and January 1, 2020 for Tier 2.

The RCA allows operation of the Tier 1 or 2 engines for the longest period possible for companies operating throughout the Sacramento region, easing the State’s attempt to transition to newer and cleaner engines that can be registered with the State. By January 1, 2017 for Tier 1 and January 1, 2020 for Tier 2, however, all Tier 1 or 2 engines must be removed from service in California.

Tier 1 or 2 portable engines are required to meet the same general operating conditions that are required of Tier 1 or 2 engines that have been registered by the State. Associated equipment must be registered in the Statewide PERP program.

Only non-rental Tier 1 or 2 engines that were “resident” in California between March 1, 2008 and December 31, 2010 are eligible for the RCA.

The payment of a penalty is required to obtain a RCA. The penalties seek to remove any financial benefit for not having permitted or registered Tier 1 or 2 engines earlier, and further encourage the phase-out of Tier 1 or 2 engines.

The RCA penalty is separate from, and in addition to, any enforcement penalty that is assessed because of the discovery of un-permitted and un-registered engines by District inspectors. There will be no enforcement penalty for Tier 1 or 2 engines disclosed for the purpose of obtaining a RCA.

Each company having Tier 1 or 2 engines and wishing to operate until January 1, 2017 for Tier 1 and January 1, 2020 for Tier 2, may enter into an agreement with any one of the regional air districts or the “Home-District” (the district in which the engine resides). If your owner/operator is from outside the Sacramento region, then you may enter into the RCA with any of the participating air districts.
