Required Action

   

January 1, 2008

Effective January 1, 2008, for alternative-fueled engines added to a fleet prior to January 1, 2009, the Responsible Official shall:

(1) install or cause to be installed and properly maintained on each portable engine subject to recordkeeping a non-resettable hour-meter; and

(2) maintain on a calendar year basis a record of the total hours of operation for each portable engine. If the portable engine is used out-of-state, then the records may account for operation within California only, excluding operation within the OCS; and

(3) maintain all required records at a central place of business for five years. The records shall clearly identify each portable engine subject to the recordkeeping requirement as well as the annual hours of operation. These records are to be made available, upon request for inspection, to local air pollution control district or CARB personnel. The requested records shall be provided to the appropriate personnel within ten business days of the request.
   

March 1, 2011

The Responsible Official of the fleet shall provide the following reports to the Executive Officer: (1) A status report, due to the Executive Officer by March 1, 2011, that includes the following items:

(A) the fleet's weighted average PM emission rate for the 2010 calendar year, including a summary for each portable engine that is part of the fleet and each engine's emission rate (g/bhp-hr); and

(B) inventory of portable engines in the fleet identifying whether the engine is state-registered or permitted/registered with the district. Alternative-fueled engines should be identified by fuel type. The inventory shall identify the make, model, serial number, year of manufacture, primary fuel type, emission factor (g/bhp-hr), and district permit or State/district registration number for each engine to be used in the fleet average determination; and

(C) identify, if applicable, each portable diesel-fueled engine that the owner commits to replacing with a Tier 4 engine, including: make, model, serial number, year of manufacture for each engine, and district permit or State/district registration number; and

(D) listing of portable diesel-fueled engines, if applicable, used exclusively in emergency applications. The listing shall identify each engine claiming use only in emergency applications, including: make, model, serial number, year of manufacture for each engine, emission factor (g/bhp-hr), and district permit or State/district registration number; and

(E) listing of portable diesel-fueled engines, if applicable, satisfying the low-use engine requirements. The listing shall identify each engine, including: make, model, serial number, year of manufacture for each engine, emission factor (g/bhp-hr), and district permit or State/district registration number; and

(F) listing of portable alternative-fueled engines, if applicable, added to the fleet prior to January 1, 2009, pursuant to ATCM section 93116.3(d)(2)(B)2. The listing shall identify each engine, including: make, model, serial number, year of manufacture for each engine, U.S. EPA engine family name, emission factor (g/bhp-hr), and district permit or State/district registration number; and

(G) for portable diesel-fueled engine(s) equipped with SCR system(s), documentation demonstrating that the SCR system is operating properly.
   

January 1, 2012

(1) Keep and maintain records for:

(A) alternative-fueled portable engines used as part of a company's fleet average, except as provided in the ATCM section 93116.4(d); and

(B) portable diesel-fueled engines affected by the use of electrification; and

(C) portable diesel-fueled engines qualifying as low-use engines; and

(D) portable diesel-fueled engines used exclusively in emergency applications.


(2) The Responsible Official, for all portable engines subject to the ATCM Section 93116.4(c)(1), shall:

(A) install or cause to be installed and properly maintained on each portable engine subject to recordkeeping a non-resettable hour-meter; and

(B) maintain on a calendar year basis a record of the total hours of operation for each portable engine. If the portable engine is used out-of-state, then the records may account for operation within California only, excluding operation within the OCS; and

(C) maintain all required records at a central place of business for five years. The records shall clearly identify each portable engine subject to the recordkeeping requirement as well as the annual hours of operation. These records are to be made available, upon request for inspection, to local air pollution control district or CARB personnel. The requested records shall be provided to the appropriate personnel within ten business days of the request.


(3) The Responsible Official of a fleet electing to use electrification in determining the fleet average shall:

(A) notify the Executive Officer identifying the dates, location, duration of the project, and a description of the project that will rely on electrification instead of using portable diesel-fueled engines. The notification shall be provided prior to the start of the project; and

(B) identify each affected portable diesel-fueled engine, including: make, model, serial number, year of manufacture for each engine, emission factor (g/bhp-hr) and district permit or State/district registration number; and

(C) shall clearly identify the electrification activity, including indicating the amount of electricity used and the time period for the project; and

(D) shall retain copies of contracts or other documentation, with the project proponent and/or applicable utility, supporting the use of grid power.


(4) Test results for SCR compliance shall be maintained at a central place of business for five years. At the request of CARB or district personnel, the Responsible Official shall have three business days to provide a copy of the most recent test results.

   

March 1, 2013, for the fleet standards that become effective January 1, 2013

March 1, 2017, for the fleet standards that become effective January 1, 2017

March 1, 2020 for the fleet standards that become effective January 1, 2020

A statement of compliance signed by the Responsible Official that the fleet standards are being achieved and a summary that identifies each portable engine in the fleet and the associated emission rate (g/bhp-hr). Portable engines included in the fleet are those that are part of the fleet at the time the fleet standard became effective. The engine identification shall include, at a minimum, the make, model, serial number, and year of manufacture for each engine. Alternative-fueled engines should be identified by fuel type.
