Tapo Incident (Oil Tank Fire in Upper Ojai)


At approximately 08:35 a.m. on Friday August 5, 2016, the Ventura County Fire Department responded to an explosion and petroleum fire in the area of 12727 Hwy 150, Ojai. The fire was contained to a storage tank that was storing approximately 2,000 gallons (42 barrels) of oil product. The fire self-extinguished and a small amount of oil product boiled over onto the immediate area surrounding the tank.


Incident response consisted of numerous public safety, emergency management, investigation and regulatory agencies. Cleanup crews are on site and working with regulators on remediation of the area.


At 12:30 p.m. a Ventura County Air Pollution Control District staff member arrived at the incident site and took a single “grab” air sample downwind of the site. As the oil odor was faint, only a single sample was taken. The sample was analyzed for a number of volatile organic compounds including Benzene, Toluene, Ethyl benzene, and Xylenes (BTEX). According to laboratory test results, the concentrations recorded were well below the levels at which adverse health effects due to short term exposure would be expected.

Oil Spill: Grove Incident Air Quality Update


On Thursday, June 23, 2016, Ventura County APCD Monitoring and Compliance staff persons were on site at the location of the Grove Incident Oil Spill and also at neighboring residences on Grove Lane. During that time, Monitoring staff captured air samples at a location approximately 10 feet above the surface of the pooled crude oil near the earthen dam constructed by Hazmat personnel in the Prince Barranca. Staff also took air samples in the neighborhood around Grove Lane, where the crude oil odor was significant, above the barranca from the pooled oil location.


APCD staff took air samples on the afternoon of the spill during the warmest time of the day and while there was still a significant amount of pooled oil in the barranca. Although the odor has been present for days now, it is reasonable to assume that the concentration of volatile organic chemicals in the air was highest on the day of the spill when the oil was most volatile and before much of the pooled crude oil was vacuumed into trucks.


The air samples were sent to a laboratory for hydrocarbon analysis. On Monday June 27, 2016, APCD staff received the results of the analysis of the collected air samples. The laboratory analysis report shows that the sample concentrations for toxic compounds present in crude oil; benzene, toluene, ethyl benzene and xylene, were somewhat elevated relative to the 2015 mean ambient concentrations observed at our Simi Valley Monitoring Station. However, the sample concentrations were below levels at which adverse health effects due to short term exposure would be expected. For more details regarding the air samples, click here.


Odors should subside as the clean-up progresses, but downwind residents may still experience some crude oil odors while the cleanup is underway. Affected residents can register odor complaints via email at, or by calling the District’s Complaint Line at (805) 654-2797.


APCD staff will continue to follow the situation and respond as needed.

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 $33 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 $33 million to Ventura County Businesses. On October 13, 2015, the Ventura County Air Pollution Control Board approved 38 new Carl Moyer Program grants totaling $2,778,060. The grants help owners of heavy-duty diesel equipment upgrade to new lower-polluting equipment. 2015 was the 17th year the District administered this program. Information on the grants awarded to Ventura County businesses can found here:


Board Letter 10/13/15

Board Letter 10/13/15 Attachment


The District is now accepting Year 18 grant applications. Application forms can be downloaded below.


The deadline for submitting grant applications is June 10, 2016. The Ventura County Air Pollution Control Board will consider all grant requests at their September 13, 2016, public meeting.


Approximately $ 4 million is available to fund projects in Ventura County this year. Eligible projects include the following:


• Repower model year 2004 and newer agricultural irrigation and water well pumps with electric motors or Final Tier 4 diesel engines. Pumps with model year 2003 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.

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.
