District Issues New Compliance Assistance Advisory:
Breakdowns at Facilities with Interruptible Grid Power


APCD Issues a Compliance Assistance Advisory regarding breakdown conditions and voluntary curtailment of electrical service.


APCD Rule 32, “Breakdown Conditions; Emergency Variances”, allows for, under certain conditions, breakdowns of air pollution control devices and continuous emissions monitoring systems where the operator will be allowed temporary relief from District enforcement action.


APCD Rule 32, states, in part: “…a breakdown condition means an unforeseeable failure or malfunction…”. It goes on to state that a breakdown condition cannot be “the result of an intentional or negligent act or omission on the part of the owner or operator.”


Electricity providers have historically offered reduced electrical service rates for account holders who agree to participate in a program that would allow periodic curtailment of electrical service to a particular facility in exchange for a reduced electric service rate. According to District policy, voluntary curtailment of electrical service due to contractual obligation is not an “unforeseeable failure or malfunction” and such a curtailment does not meet definition of a breakdown, as defined in APCD Rule 32.


District will no longer accept any voluntary electrical curtailment as a breakdown and the operator will not be afforded relief from District enforcement action if a violation occurs as a result of such a curtailment.


2016 Ventura County Air Quality Management Plan


The Ventura County Air Pollution Control Board adopted the 2016 Ventura County Air Quality Management Plan (AQMP) on February 14, 2017. The 2016 AQMP presents Ventura County’s strategy (including related mandated elements) to attain the 2008 federal 8-hour ozone standard by 2020, as required by the federal Clean Air Act Amendments of 1990 and applicable U.S. EPA clean air regulations.

Photochemical air quality modeling and related analyses, including a Weight of Evidence assessment conducted for the 2016 AQMP, indicate that Ventura County will attain the 2008 federal 8-hour ozone standard by 2020 using local, state, and federal clean air programs. Similarly, the required Reasonable Further Progress (RFP) demonstration shows that Ventura County will achieve the required annual incremental emissions reductions for the purpose of ensuring attainment by the attainment year.

The 2016 AQMP was prepared to satisfy federal Clean Air Act planning requirements for areas designated as serious federal 8-hour ozone nonattainment areas, including, but not limited to, updated air quality information, an updated emissions inventory, local and state air pollutant control measures, new emission forecasts and projections, a new federal conformity budget for transportation projects, a reasonable further progress demonstration for precursors of ozone (reactive organic gases and nitrogen oxides), a demonstration that Ventura County will attain the 2008 federal 8-hour ozone standard, and contingency measures.

New Compliance Assistance Advisory: APCD to Temporarily Suspend Enforcement of the Upcoming 2017 Fleet Emission Standards and Fleet Reporting Requirements for Portable Diesel Engine Fleets.


Portable Diesel EnginesAPCD Issues a Compliance Assistance Advisory directed at owners and operators of portable diesel engine fleets. The California Air Resources Board (ARB) has determined that widespread compliance with the upcoming 2017 Fleet Average Emission Standard and associated reporting requirements in the state’s Airborne Toxic Control Measure for Diesel Particulate Matter from Portable Engines (ATCM) may not be feasible.


In light of the uncertainty regarding the 2017 standard (and 2020 standard), ARB intends to revise the ATCM. ARB has asked local air districts to temporarily suspend enforcement of sections of the ATCM related to the upcoming fleet average emission standard and associated reporting requirements until the regulation can be revised and approved by its governing Board. This applies to all portable diesel engines whether they are registered with the Statewide Portable Engine Registration Program (PERP), or operating under an APCD Permit to Operate.


To that effect, ARB has released Advisory Number 347, informing the regulated community of its intent to suspend enforcement and revise the ATCM. You can download a copy of Advisory Number 347 here.


Carl Moyer Incentive Program Awards $37 Million to Ventura County Businesses



The Carl Moyer Memorial Air Quality Standards Attainment Program (Carl Moyer Program) is an incentive program offered jointly by the California Air Resources Board and California’s local air districts. The program provides grants for cleaner-than-required engines and equipment to help improve air quality in California. The grants are administered by the local air districts. The program is named after the late Dr. Carl Moyer in recognition of his work in the air quality field and his efforts in bringing about this incentive program.


Since 1999 the program has awarded over $37 million to Ventura County businesses. On November 8, 2016, the Ventura County Air Pollution Control Board approved 45 new Carl Moyer Program grants totaling $3,932,419. The grants help owners of heavy-duty diesel equipment upgrade to new lower-polluting equipment. 2016 was the 18th year the District administered this program. Information on the grants awarded to Ventura County businesses can found here:


The District is now accepting Year 19 grant applications. Application forms can be downloaded below.


The deadline for submitting grant applications is July 14, 2017. The Ventura County Air Pollution Control Board will consider all grant requests at their October or November public meeting.


Approximately $2.5 million will be available to fund projects in Ventura County in 2017. Eligible projects include the following:


- Repower model year 2005 and newer agricultural irrigation and water well pumps with electric motors or Final Tier 4 diesel engines. Pumps with model year 2004 and older engines are no longer eligible for grant funding.


- Repower commercial fishing boats with new lower emission engines.


- Replace farm tractors and construction equipment with new lower emission equipment.


- Repower farm tractors, construction equipment, and locomotives with new lower emission engines.


As a reminder, the following restrictions implemented in 2015 are still in effect:


1. If the hour meter on a farm tractor is not currently working or was replaced or repaired after July 14, 2015 (two years before the current deadline), the tractor is not eligible for funding in 2017.


2. No single grantee or group of grantees under common control shall be granted more than $400,000 in 2017. The APCO can make an exception for cases where a single piece of equipment costs more than $400,000 to replace or repower.


Grant application forms for 2017 are posted below. Please call or email Tyler Harris, Air Quality Engineer, at (805) 645-1407;, for additional information. Information is also available at these links:

California Air Pollution Control Officers Association (CAPCOA) - Explanation & Examples of Uses of PERP


Questions are often raised about what constitutes portable versus stationary operation of equipment. The PERP regulation defines portable operation and stationary sources. There are some specific circumstances where, depending on each situation, the use of PERP-registered units may not be compatible with the objectives of PERP and the District. These determinations are very fact dependent, so we recommend you contact the District with questions about whether your portable equipment operation requires a District permit or can use PERP registration.


The California Air Pollution Control Officers Association (CAPCOA) has prepared a document which addresses these issues: Explanation & Examples of Uses of PERP


Replacing Tier 1 & Tier 2 Ag Engines: Check Before You Buy!


APCD issues a Compliance Assistance Advisory regarding the California Air Resources Board’s Air Toxic Control Measure for Stationary Compression Ignition Engines (ATCM) requirement to replace Tier 1 and Tier 2 diesel Ag engines.

The ATCM prohibits the operation of Tier 1 and Tier 2 agricultural engines after December 31, 2014 for engines rated at 175 BHP or greater and December 31, 2015 for engines rated at 50 to 174 BHP.

Check before you buy! This advisory informs owners or operators of Tier 1 & Tier 2 Ag engines that not all Tier 4 or Interim Tier 4 diesel engines will meet the upcoming ATCM emission standards, and advises them to check before they buy a new engine. The upcoming emission standards are contained in the advisory. Another option is to buy an electric motor instead of a diesel engine.

There will be a limited amount of funding available to qualified applicants to help purchase a new diesel engine, or electric motor.

All Ag engines 50 horsepower and greater, including new replacement engines, are required to be registered with the APCD. For information on the District’s agricultural engine registration program please click here.
