State government players l.jpg
State Government Players

  • Cal Legislature approves bill

  • Governor signs bill into law

  • Governor with legislative approval appoints Air Resources Board (ARB)

  • ARB directs ARB staff(Cal EPA) to develop regulation implementing law

  • ARB approves regulation and authorizes ARB staff to implement and enforce

National ambient air quality standards naaqs l.jpg
National Ambient Air Quality Standards NAAQS

  • Health Based – population exposure

  • PM2.5, PM10, Ozone, CO, NO2

  • States can use economics to find least cost approach to meeting NAAQS but cannot use cost as an argument for avoiding NAAQS

Link between engine emissions and naaqs l.jpg
Link Between Engine Emissions and NAAQS

NOX (exhaust) + atmospheric gases = PM2.5

NOX, Hydrocarbon (exhaust) + atmospheric gases = ozone

Authority to regulate emissions l.jpg
Authority to Regulate Emissions

  • California must meet NAAQS as required by Federal Clean Air Act (CCA) and Cal Clean Air Act

  • CAA defers certain legal authorities to California to control engine emissions

Naaqs legal requirements l.jpg
NAAQS Legal Requirements

  • California must meet PM2.5 NAAQS by 2015

  • All California air districts must meet ozone NAAQS between present and 2023

  • California must provide EPA PM2.5 (2008)and Ozone (2007) State Implementation Plans (SIP’s) showing how the state will comply with NAAQS

  • SIP planning provides emission budgets to various emitting groups

Diesel risk reduction program l.jpg
Diesel Risk Reduction Program

1983: California Legislature enacted Bill (AB) 1807: Health and Safety Code 39650-39674) to reduce exposure to toxic air contaminants (TACs)

8/1998: ARB identified diesel PM as a TAC (71.2% of statewide cancer risk)

9/2000: Board approves Diesel Risk Reduction Plan that requires specific (ATCMs) regulations designed to reduce diesel PM emissions to the greatest extent feasible & at least 85% by 2020

Regulatory process l.jpg
Regulatory Process

  • Legal Authorization to regulate is established

  • Regulating Agency analyzes technology and feasibility – seeks input from regulated sector

  • Agency refines analysis & proposes regulatory language

  • Public Meetings & public comment

Regulatory process concluded l.jpg
Regulatory Process- Concluded

  • Agency proposes final rule at Public Hearing with Statement of Reason (SOR)

  • Legal entity ( For Air, Air Resources Board) approves rule

  • Office of General Counsel approves rule

  • Agency implements rule

How businesses can affect regulations l.jpg
How Businesses Can Affect Regulations

  • Generally, a regulatory action cannot be stopped once initiated

  • Business cannot benefit by entering late in the regulatory process

  • Business must interact with the Agency and provide honest information regarding the impact of the proposed rule

Portable equipment regulations l.jpg

Portable Equipment Regulations

“Equipment You Tow”

Regulations l.jpg

  • Portable ATCM: Sets out emission requirements to the AQMD’s

  • PERP (Registration): Sets out a statewide registration option to permitting each portable engine in affected districts

Air toxic control measure l.jpg
AIR Toxic Control Measure

  • ATCM is used as the primary legal authority to regulate fleet emissions

  • Portable ATCM specifies fleet emission and reporting requirements

Portable atcm l.jpg
Portable ATCM

  • Applies to 50 hp and larger portable engines

  • January 1, 2006: most stringent standards are required for new engines

  • 93116.3(b) Requires all portable engines (exceptions) to be Tier 1 or higher January 1, 2010

  • 93116.3(c) Requires portable fleets (exceptions) to meet increasingly stringent average emissions weighted by horsepower by 1/13 , 1/17, 1/20

Portable atcm19 l.jpg
Portable ATCM

  • 93116.4 Record Keeping: Begins January 1, 2008 for alternative fueled engines

    Ends when fleet is Tier 4 or “equal”

  • March 1, 2011 Provide fleet inventory report and fleet average for 2010

  • March 1, 2013, 2017, 2020- Provide Compliance Certifications and Reports

Perp registration l.jpg
PERP- Registration

  • Applies to 50 hp and larger portable engines and Portable Equipment Units. Under 50 hp certified engines may be registered

  • DI and SI engines

  • Portable engine- Compressor, welder, generator etc- cannot be driven!

  • Equipment Unit produces PM-10 as well as PM2.5 from engine (e.g. crushing plant)

  • Located at a fixed site for less than 1 year

Slide21 l.jpg

  • Voluntary program

    • Legally, all portable engines must be registered in the state program or permitted in each district where the engine operates

    • Harmonized with ATCM so permitting requirements at District are at least as stringent as PERP

Slide22 l.jpg

  • Engines and equipment units must be registered separately

  • Misrepresentation is a violation subject to enforcement

  • ARB has 90 days to issue or deny a registration

  • Legally, you cannot put portable equipment into service without an issued registration

Slide23 l.jpg

Eligible Engines – New Registration

  • Certified diesel engine

  • Certified spark-ignition engine

  • Must be one of the following:

    • Most stringent emission standard engine

    • Flexibility Engine

    • Resident Engine

  • Must have non-resettable hour meter

Slide24 l.jpg

Most Stringent Standard

  • If you order with 6 months before a change in standards

  • You can verify the order

  • You take possession after change in standards

  • You have 6 months after the standards change to register previous standard unit

Slide25 l.jpg

Most Stringent Standard

  • This means newest Tier or most modern SI

  • ARB can waive most stringent standard requirement if sufficient most stringent standard engines do not exist

Slide26 l.jpg

Flexibility Engine

  • These are engines of older emissions standards that are allowed to be sold by a volume formula established by EPA to help smooth out supply problems during transition to new standards

  • The flexibility engine might have a tag such as:


Slide27 l.jpg

Resident Engine

  • A Tier 1 or higher engine that was provenly operated in California Between 1/1/04 & 10/1/06

    • Can be registered between 1/1/07 and 12/31/09

    • Total fees include new registration, mandatory inspection, back fees to date specified by ARB (typically purchase date), penalty

    • Penalties increase with time

  • ATCM allows Tier 0 engines to be permitted at the discretion of a local district - not eligible for PERP

  • Fleets doing 100% business in attainment areas (Captive attainment area fleet): Meet PM fleet average only

  • No engine Tier limitations

  • Emission Credits for averaging

    • Electric and alternative fueled vehicles

Mobile in use45 l.jpg
Mobile In-Use

Averaging Calculation

  • Average can be statewide or by location

  • Weighted emission average by horsepower - ARB provides emission factors to be used for all engines

  • Emission targets - ARB provides targets for all years beginning in 2010

  • Fleet average cannot exceed either NOX or PM target

Mobile in use46 l.jpg
Mobile In-Use

  • Impact on Rental Fleets:

    • If a fleet contains models with 11 model years or less equally distributed over model years, it will probably pass the fleet average requirements

    • For lower horsepower fleets, NOX is limiting

    • For larger horsepower fleets, PM is limiting

    • If a fleet fails the averaging requirements, it must comply through Best Available Control Technology (BACT)

Mobile in use47 l.jpg
Mobile In-Use

Fleet Size Changes with Averaging

  • Rules for changing fleet categories related to reporting

  • Rules for movement in and out of the state during a given year

  • Fleets can grow and shrink as long as averaging requirements are “continuously” met

Mobile in use48 l.jpg
Mobile In-Use

BACT Requirements

If fleet fails NOX average

  • Replace 8%( until 2015) and 10% (after March 1 2015) of fleet annually with higher Tier vehicles ( can be used vehicles)

  • If SCR becomes available, it can be used instead of replacement

  • Owner can bank credits for early retirement

  • Order of turnover rules

  • Vehicles less than 10 years old exempt

Mobile in use49 l.jpg
Mobile In-Use

BACT Requirements

Test fleet PM average

  • If fails, retrofit 20% vehicles annually with VDECS (state approved particulate filters with 50% or more efficiency)

  • Owner can bank credits for early retrofit

  • Exempt if VDECS not available or make for unsafe operation

  • Order and replacement of retrofit rules

  • VDECS less than 6 years old exempt

Mobile in use50 l.jpg
Mobile In-Use

Adding vehicles under BACT

  • Fleets can grow and shrink

  • Can add vehicles if Tier 2 or higher

  • All fleets: emission factor equal to or less than current fleet target for PM

  • Large and Medium fleets: emission factor equal to or less than current fleet target for NOX

Mobile in use51 l.jpg
Mobile In-Use

BACT Tier 1 Provision

Who must meet this regulation?

  • Applies to fleet operators with owned equipment and equipment leased or rented for more than 1 year period

  • Operator “means a person with legal right of possession and use of LSI engine equipment other than a person whose usual and customary business is the rental or leasing of LSI engine equipment. Operator includes a person whose usual and customary business is the rental and leasing of LSI engine equipment for ant LSI engine equipment not solely possessed or used for rental or leasing”

Large spark ignition engines68 l.jpg
Large Spark Ignition Engines

  • Rental fleets have no direct regulatory requirements as long as equipment is used exclusively for rental or leasing

  • Don’t use LSI equipment in the yard unless you are a small LSI fleet

  • Rental fleets are impacted by how renters can use their equipment

Large spark ignition engines69 l.jpg
Large Spark Ignition Engines

  • For rental equipment:

    • Renter need not average short term rental into his fleet if it meets 2004 standards between 1/1/2009 and 12/31/2010

    • Renter need not average short term rental into his fleet if engine meets 2007 standard or higher after 12/31/2010

    • If rental company has “new equipment”, fleet operator may benefit by averaging rental in

Small off road engines sore l.jpg
Small Off-Road Engines (SORE)

  • Applies to gasoline fueled under 25 hp engines

  • This rule is related to the manufacture and selling of certified equipment

  • There are currently no in-use rules related to SORE that impact rental businesses

Toxic hot spots rule l.jpg
Toxic Hot Spots Rule

  • Air Toxic Hot Spots: Authorized by AB 2588, September 1987

  • Controls routine release of toxic emissions from facilities located close to receptors like homes, schools and hospitals

  • Rental Yards might be “facilities”

  • Rule applies to individual yards, not statewide fleets

Toxic hot spots l.jpg
Toxic Hot Spots

  • You do not want your rental yard to be a hot spot!

Toxic hot spots73 l.jpg
Toxic Hot Spots

  • “Facilities” applies to stationary equipment in rental yard

  • Diesel stationary equipment operated more than a total of 20 cumulative hours per year could result in a hot spot designation

  • Portable diesel equipment is considered to be stationary equipment for this rule

Toxic hot spots74 l.jpg
Toxic Hot Spots

Stationary Engines

  • Rule is in effect

  • Enforced by local district

  • Refers to any diesel equipment fixed in your yard. Such applications could be sump pumps, pressure washers, generators, air compressors etc.

  • Refers to any stationary spark engine allowed but emissions are much greater

Toxic hot spots75 l.jpg
Toxic Hot Spots

Portable Engines

  • For hot spots, all portable diesel engines, count, including engines above and below 50 hp

  • Hot spot designations based upon portable engines start in 2010

  • Before 2010, you are exempted from controlling emissions from portable diesel engines

Toxic hot spots76 l.jpg
Toxic Hot Spots

  • Mobile diesel equipment is not considered under “facility” definition

Toxic hot spots77 l.jpg
Toxic Hot Spots

20 Hour Criteria

  • Actually, the allowed hours of operation depends on how close the nearest receptor is, how large your fleet is, how dirty the fleet is, and home many hours you operate the fleet

  • Practically, you might have no problems if nearest receptor is 500 to 1000 feet from the source and/or your “stationary” equipment is high Tier

Toxic hot spots78 l.jpg
Toxic Hot Spots

What do you need to do?

It is the local district’s responsibility to ask you for compliance data.

If you are located in a metropolitan area, and especially the South Coast:

  • Minimize all diesel operation on your site

  • Do not give neighbors reason to call inspector

  • Quantify your diesel emissions from your “stationary” sources
