INFORMATIVE DIGEST OF PROPOSED ACTION/POLICY STATEMENT OVERVIEW
Sections Affected: Amendment to the following sections of title 13, California Code of Regulations and the documents incorporated by reference therein: chapter 2, Enforcement of Vehicle Emission Standards and Surveillance Testing; article 2.1, Procedures for In-Use Vehicle Voluntary and Influenced Recalls; sections 2111 and 2112; chapter 2, Enforcement of Vehicle Emission Standards and Surveillance Testing; article 2.3, In-Use Vehicle Enforcement Test Procedures; section 2139 and 2140; chapter 2, Enforcement of Vehicle Emission Standards and Surveillance Testing; article 2.4, Procedures for Reporting Failures of Emission-Related Components; section 2147; chapter 9, Off-Road Vehicles and Engines Pollution Control Devices; article 4.7, Spark-Ignition Marine Engines; sections 2440-2446; and the incorporated "California Exhaust Emission Standards and Test Procedures for 2001 Model Year and Later Spark-Ignition Marine Engines;" and the adoption of chapter 9, Off-Road Vehicles and Engines Pollution Control Devices; article 4.7, Spark-Ignition Marine Engines; section 2444.2.
The California Clean Air Act, as codified in the Health and Safety Code sections 43013 and 43018, specifically mandated ARB to regulate off-road mobile sources of emissions. Included are marine vessels, locomotives, utility engines, off-road motorcycles, and off-highway vehicles. In 1998, the Board approved regulations to control emissions from spark-ignition personal watercraft and outboard marine engines. For these types of engines, the regulations became effective with the 2001 model year. The amendments proposed herein seek to reduce hydrocarbon (HC) emissions and oxides of nitrogen (NOx) emissions from spark-ignition inboard and sterndrive marine engines, effective with the 2003 model year.
In crafting the proposal, ARB staff met with engine manufacturers and other interested parties in numerous individual and group meetings, including trips to marine engine manufacturing facilities, as well as conference calls. The staff also held a public workshop on September 19, 2000.
The proposal applies to spark-ignition inboard and sterndrive marine engines. Specifically, California’s spark-ignition marine engine regulations would be amended to include inboard and sterndrive engines. Thus, these engines would be subject to exhaust emission standards, certification test procedures, on-board diagnostic systems, compliance provisions, consumer provisions such as environmental labeling, and warranty requirements.
The proposed exhaust emission standards are shown below in Table 1. The standards commence with the 2003 model year, followed by more stringent levels that are phased-in beginning in 2007.
Inboard and Sterndrive
Exhaust Emission Standards
(1) Sales-weighted corporate average, through 2008 model year.
(2) Phased-in standard, reaching 100% compliance with 2009 model year.
Beginning with the 2003 model year, inboard and sterndrive marine engines must show compliance with the 15.0 grams per kilowatt-hour HC+NOx standard. This standard will keep inboard and sterndrive marine engine exhaust emissions at or below existing levels. This standard, based on a corporate average methodology for demonstrating compliance, provides manufacturers flexibility to comply with the regulations. Additionally, crankcase emissions will no longer be vented into the ambient atmosphere.
With the 2007 model year, manufacturers must comply with the catalyst-based 5 grams per kilowatt-hour HC+NOx standard. These standards are expected to require three-way catalyst, closed-loop technology to comply with the more stringent HC+NOx standards. Specifically, for each engine manufacturer’s California production, at least 10 percent of the engines in 2007, 50 percent in 2008, and 100 percent in 2009 and beyond would comply with the 5 grams per kilowatt-hour HC+NOx standard. A phase-in provides industry with flexibility to develop these engines over a period of years.
Small volume manufacturers will have the option to delay compliance until 2009. Inboard and sterndrive engines rated over 373 kilowatts (500 horsepower) will also be exempted from the standards until 2009. Thus by 2009, all new engines produced for sale in California and not manufactured exclusively for competition would be subject to the more stringent exhaust emission standards.
The 2007 and later model year engines complying with the catalyst-based 5 grams per kilowatt-hour HC+NOx standard will be required to incorporate a computer-controlled on-board diagnostic system. This type of system monitors the engine, identifies emission-related malfunctions, and stores retrievable data related to the malfunction (in the form of a diagnostic trouble code(s)) in the computer’s memory so that the malfunctions can be corrected. In the event of a malfunction, the system will emit either an audio or visual alert.
Initially, the 2003-2008 model year inboard and sterndrive engines would be required to provide a two-year emissions defects warranty to the ultimate purchaser. By 2009, the engines would be warranted for three years. This warranty ensures that emission-related parts are free of defects.
Compliance of production engines subject to this rulemaking would be determined using selective enforcement audit (SEA) testing. Procedurally, this program is identical to that used by the United States Environmental Protection Agency (U.S. EPA) and, as the name implies, would be used when the Executive Officer has reason to believe that the emissions of the engines being produced during the production run may exceed the standards.
To ensure that 2009 and later model year engines are meeting the emission standards throughout their 480-hour/10-year compliance period; staff also proposes ARB’s traditional in-use testing program. For any engine family selected for testing under this program, exhaust emission testing would be performed on an appropriate sample of in-use engines. If an engine family exceeds the applicable HC+NOx standard on average, the manufacturer would be subject to recall provisions to remedy the noncompliance.
Staff is also proposing that inboard and sterndrive engines participate in the engine and environmental labeling programs for marine engines. The engine label identifies the engine as compliant with California regulations and may be used for enforcement purposes. The environmental labeling program denotes the relative level of emissions emitted by the engine. Currently, for personal watercraft and outboard marine engines, there are three tiers that represent graduated levels of reduced emissions. The proposal adds a fourth tier, which is appropriate for inboard and sterndrive engines certified to 2007 catalyst-based exhaust emission standards. Upon demonstration of compliance to the applicable emission standard, 2003 and later model year inboards and sterndrives shall display the corresponding emission label.
RELATED FEDERAL ACTIONS
In 1996, U.S. EPA adopted exhaust emission standards for personal watercraft and outboard marine engines. Although U.S. EPA has recently issued an Advance Notice of Proposed Rulemaking that seeks to include inboard and sterndrive marine engines, there currently are no federal regulations for these classes of engines.
BENEFITS OF THE PROPOSAL
The staff analysis indicates that by 2020, the proposal will reduce HC by 11 tons and NOx by 45 tons per summer weekend day. The combined 56 tons per day reduction is equivalent to removing 1.6 million cars from the road in 2020. The combined HC+NOx reductions would cost less than $3.50 per pound reduced, which is within the range of cost-effectiveness of other ARB and district emission reduction programs.

COSTS TO PUBLIC AGENCIES AND TO BUSINESSES AND PERSONS AFFECTED
The determinations of the Board's Executive Officer concerning the costs or savings necessarily incurred in reasonable compliance with the proposed regulations are presented below.
The Executive Officer has determined that the proposed regulatory action will not create costs or savings, as defined in Government Code section 11346.5(a)(6), to any state agency or in federal funding to the state, costs or mandate to any local agency or school district whether or not reimbursable by the state pursuant to part 7 (commencing with section 17500), division 4, title 2 of the Government Code, or other nondiscretionary costs or savings to local agencies. However, the Air Resources Board may incur additional implementation or enforcement costs at some future time.
The Executive Officer has also made an initial determination that adoption of the proposed regulatory action will not have a significant statewide adverse economic impact directly affecting businesses, including the ability of California businesses to compete with businesses in other states.
The Executive Officer has also determined that there will be no, or an insignificant cost impact on representative private persons or businesses resulting from the proposed action.
Furthermore, the Executive Officer has initially assessed that the proposed regulatory action will not affect the creation or elimination of jobs within the State of California, the creation of new businesses or elimination of existing businesses within California, or the expansion of businesses currently doing business within California. An assessment of the economic impacts of the proposed regulatory action can be found in the Staff Report.
Before taking final action on the proposed regulatory action, the Board must determine that no alternative considered by the agency or that has otherwise been identified and brought to the attention of the Board would be more effective in carrying out the purpose for which the action is proposed or would be as effective and less burdensome to affected private persons than the proposed action.
Finally, the Executive Officer has also determined that the proposed regulatory action may affect small businesses.
