Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

EPA is finalizing approval of a revision to the Maricopa County Environmental Services Department (MCESD) portion of the Arizona State Implementation Plan (SIP). This revision was proposed in the Federal Register on May 24, 2001 and concerns volatile organic compound (VOC) emissions from automotive windshield washer fluid. We are approving a local rule that regulates these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).

EFFECTIVE DATE:

This rule is effective on December 31, 2001.

I. Proposed Action

On May 24, 2001 (66 FR 28685), EPA proposed to approve the following rule into the Arizona SIP. Start Printed Page 59700

Local AgencyRule #Rule TitleAdoptedSubmitted
MCESD344Automobile Windshield Washer Fluid04/07/9908/04/99

We proposed to approve this rule because we determined that it complied with the relevant CAA requirements. Our proposed action contains more information on the rule and our evaluation.

II. Public Comments and EPA Responses

EPA's proposed action provided a 30-day public comment period. During this period, we received comments from the following party.

1. D. Douglas Fratz and Joseph T. Yost, Consumer Specialty Products Association (CSPA); letter dated June 22, 2001.

CSPA's comments pertain to the test method, Maricopa County Reference Method #100 (RM 100), used for determining compliance, and to the consistency of MCESD Rule 344 with other consumer product regulations. CSPA's comments and our responses are summarized below.

Comment: Because RM 100 reports results as total organic carbon and different VOCs have different percentages of carbon, it is not possible to accurately convert RM 100 results into the terms in which the limits of MCESD Rule 344 are expressed, mass of VOC.

Response: Conversion of RM 100 test results from mass of carbon to the mass of VOC is relatively simple for windshield washer fluids (WWF) containing a single VOC and slightly more complex for WWFs containing multiple VOCs.

Converting the mass of carbon from the test result to mass of VOC involves multiplying the test results by the ratio of molecular weights. Based on EPA's survey used to develop the national Consumer Products Rule (40 CFR part 59, subpart C) and the California Air Resources Board's (CARB) consumer products speciation profile [1] for automobile WWFs, the predominant VOC used in WWFs is methanol. If methanol is the only VOC present, the conversion factor from mass of carbon to mass of VOC is 32/12. For WWFs containing multiple VOCs, the conversion from mass of carbon to mass of VOC can still be done if the VOCs and their approximate proportions are known.

RM 100 allows the use of either infrared (IR) or flame ionization (FID) detectors. If an IR or FID detector is calibrated with methanol, and methanol is the only VOC present, then a laboratory could report results directly as percent methanol. If VOCs other than methanol are present, then this method would tend to overestimate the total mass of VOC. Only if the results from these methods exceed the limits of MCESD Rule 344 would further data reduction and investigation using the above mass of carbon to mass of VOC conversion method be necessary. EPA may also approve other methods should they be submitted for evaluation.

Comment: RM 100 will overestimate the total organic carbon associated with VOCs for WWFs containing one or more exempt compounds because it does not distinguish between organic carbon from VOCs and organic carbon from non-precursor organic compounds.

Response: Maricopa County's list of non-precursor organic compounds is the same as EPA's. There are relatively few compounds on that list that could be used in WWFs because many are not soluble in water. Acetone is one of the few compounds that is soluble in water but is unlikely to be used in WWFs because of its potential to damage a vehicle's paint. If WWFs contain exempt solvents, manufacturers would be allowed to subtract the mass of exempt solvents from the mass of VOC and could petition the MCESD for an alternative method by which to do that.

Comment: RM 100 will overestimate the total organic carbon associated with VOCs because it does not distinguish between volatile organic compounds and non-volatile organic compounds. Certain compounds in WWFs, like organic dyes or other non-volatile organic compounds, cannot participate in the atmospheric photochemical reactions that produce ozone because they do not volatilize to the air.

Response: While it is difficult to know how significantly dyes or other non-volatile organic compounds might increase the total VOC content of WWFs, a review of material safety data sheets indicates that the actual mass of dyes and other non-volatile organic compounds added to WWFs tends to be small. If the amount of non-volatile organic compounds is considerable and may influence a compliance determination, EPA recommends the manufacturer petition the MCESD for alternative methods to exclude the mass of dyes and non-volatile organic compounds from the mass of VOCs.

Comment: Rule 344 is problematically inconsistent with analogous federal and California regulations. Specifically, many products that would comply with a 10 percent VOC limitation according to EPA and California regulations may not comply with that same limitation under the provisions of MCESD Rule 344 because: (1) There is no process to sell-through a product that exceeds the VOC limit but was manufactured before the effective date of the rule, (2) “low vapor pressure” (LVP) compounds that are not volatile are not exempted, (3) the types of “reasonable prudent precautions” allowed in all other consumer product rules to assure that a non-complying product sold in the County will be resold for use outside the County are artificially restricted under the rule, (4) concentrated product labels with dilution instructions resulting in stronger WWF formulations for users outside of Maricopa County are not allowed, and (5) an “innovative products” provision which allows products to exceed the applicable VOC limit if the use of such “innovative products” ultimately results in lower VOC emissions is not allowed.

Response: While we appreciate that consistency is desirable for affected industry, state and local agencies have broad authority to develop regulations and are not required to be consistent in all regards. In fact, section 59.211 of the final national Consumer Products Rule explicitly provides that states and their political subdivisions retain authority to adopt and enforce their own additional regulations affecting these products. Accordingly, MCESD may impose more stringent requirements for WWFs as part of its SIP and its election to do so is not a basis for EPA to disapprove the SIP. See Union Electric Co. v. EPA, 427 U.S. 246, 265-66 (1976). EPA favors national uniformity in consumer and commercial product regulation, but recognizes that some localities may need more stringent regulation to combat more serious and more intransigent ozone nonattainment problems.

Furthermore, while California consumer products regulations allow products to be sold, supplied, or offered for sale up to three years after the Start Printed Page 59701effective date of the rule, MCESD Rule 344 is consistent with the national Consumer Products Rule which does not contain a sell-through period. As explained in the background document,[2] manufacturers' current “just in time” inventory practices and the expense and lack of sufficient storage space do not create large stockpiles of noncomplying products which might warrant a sell-through period. EPA considers the incorporation of a sell-through period to be at the discretion of the local agency.

The amount of LVP compounds such as surfactants or ethylene glycol used in WWFs tends to be minimal so as not to affect a product's ability to clean and evaporate quickly without leaving a residue. A review of the CARB's Initial Statement of Reasons for Proposed Amendments to the California Consumer Products Regulation dated September 10, 1999 indicates that surfactants in a possible windshield washer formulation may account for 0.05 weight percent. As stated above, EPA cannot object to MCESD Rule 344 taking a more stringent approach than the national Consumer Products Rule and concurs with MCESD's decision to not exempt LVP compounds in Rule 344.

Section 303 of MCESD rule 344 exempts non-complying WWFs destined for use outside of Maricopa County. Section 303 also specifies the information required to prove that non-complying products sold within Maricopa County are actually destined for use outside of the County. Although MCESD Rule 344 is more prescriptive than California's Consumer Products Rule which allows manufacturers and distributors of non-compliant products some flexibility to take “reasonable prudent precautions” to assure that the consumer product is not distributed in California, Rule 344, as written, meets EPA's enforceability requirements.

MCESD adopted requirements in section 302e of Rule 344 that prohibit the dilution of WWFs that would yield solutions that exceed the VOC limit of the rule. Labeling products with directions which yield WWFs that are more concentrated than the 10% VOC limit is potentially confusing to the end user in the County and may create more enforcement problems. The requirement that all dilution instructions for concentrated products never exceed 10% ensures that MCESD will achieve the emissions reductions expected from Rule 344. EPA supports MCESD's intent to establish clear, enforceable labeling requirements.

Inclusion of an innovative products provision in MCESD Rule 344 would allow greater flexibility for manufacturers to meet Rule 344's VOC content limit. However, California has had a 10% VOC limit for WWFs since 1993 and no innovative product requests for WWFs have been submitted to CARB. Therefore, EPA considers Maricopa County's limit of 10% to be reasonable and achievable.

III. EPA Action

None of the submitted comments change our assessment that the submitted rule complies with the relevant CAA requirements. Therefore, as authorized in section 110(k)(3) of the Act, EPA is fully approving this rule into the Arizona SIP.

IV. Administrative Requirements

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 32111, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001). This action merely approves state law as meeting federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).

This rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This action also does not have Federalism implications because it does not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely approves a state rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This rule also is not subject to Executive Order 13045, “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), because it is not economically significant.

In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the Clean Air Act. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).

Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by January 29, 2002. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and Start Printed Page 59702shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
