Start Preamble


Environmental Protection Agency (EPA).


Final rule; technical corrections.


Under the Clean Air Act (CAA), the EPA issued a final rule entitled “Standards of Performance for New Stationary Sources and Guidelines for Control of Existing Sources: Municipal Solid Waste Landfills,” published in the Federal Register on March 12, 1996 (61 FR 9905). A subsequent direct final rule, published Start Printed Page 18907on June 16, 1998 (63 FR 32743) corrected errors and clarified regulatory text of the final rule. These technical corrections will correct an error in the amendatory instructions and an inconsistency between the reportable exceedances and reporting of monitoring data. Section 553 of the Administrative Procedure Act, 5 U.S.C. 553(b)(B), provides that, when an agency for good cause finds that notice and public procedure are impracticable, unnecessary or contrary to the public interest, the agency may issue a rule without providing notice and an opportunity for public comment. The EPA has determined that there is good cause for making today's rule final without prior proposal and opportunity for comment because the changes to the rule are minor technical corrections, are noncontroversial in nature, and do not substantively change the requirements of the NSPS/EG rule. Thus, notice and public procedure are unnecessary. The EPA finds that this constitutes good cause under 5 U.S.C. 553(b)(B).


These technical corrections are effective April 10, 2000.


Docket No. A-88-09 contains the supporting information used in the development of this rulemaking. The docket is located at the U.S. Environmental Protection Agency in Room M-1500, Waterside Mall (ground floor), 401 M Street SW, Washington, DC 20460, and may be inspected from 8:30 a.m. to 5:30 p.m., Monday through Friday, excluding legal holidays.

I. Background

On March 12, 1996, the EPA promulgated in the Federal Register (61 FR 9919) EG for existing municipal solid waste landfills and the NSPS for municipal solid waste landfills. These regulations and guidelines were promulgated as subparts Cc and WWW of 40 CFR part 60. This action corrects an error in the amendatory instructions, typographic and formatting errors, and it corrects three inconsistencies in the direct final action published on June 16, 1998.

II. Description of Corrections

A. Amendatory Instruction Error

Due to an error in the amendatory instructions for the direct final rule published in the Federal Register on June 16, 1998, § 60.752(b)(2)(ii) (A) and (B) and § 60.752(b)(2)(iii)(B) (1) and (2) were incorrectly removed. These technical corrections add those paragraphs back into the final rule.

B. Inconsistencies

An inconsistency exists between what constitutes a reportable exceedance for boilers and process heaters in § 60.758(c)(1)(i), and the monitoring (§ 60.756(b)(1)) and recordkeeping (§ 60.758(b)(2)) requirements for these devices. Boilers and process heaters with design heat input capacity less than or equal to 44 megawatts are required to monitor temperature and keep records. A reportable exceedance related to temperature can only occur for boilers and process heaters that are less than 44 megawatts. It was not our intent to require monitoring and recordkeeping for boilers and process heaters if their design heat input capacity is equal to or greater than 44 megawatts.

C. Typographical and Formatting Errors

A typographical error appearing in the equation in §§ 60.754(a)(1) (i), (ii) and 60.759(a)(3)(ii) is being corrected. The term “CNNM MOC” is corrected to read “CNMOC”, meaning the concentration of non-methane organic compounds.

A typographical error appearing in § 60.754(a)(1)(ii) is being corrected. The paragraph immediately following the list of terms to the equation in this section was incorrectly duplicated from the paragraph in § 60.754(a)(1)(i). The paragraph is amended to correctly reflect the method for subtracting nondegradable solid waste when actual year-to-year solid waste acceptance rates are known.

A formatting error in § 60.756(a), introductory text, is being corrected. A comma was left out between the words “thermometer” and “other.”

A typographical error appearing in § 60.757(c) is being corrected. Throughout the rule, various requirements are triggered by the emission rate cutoff of “equals or exceeds 50 megagrams per year.” The term “equals or” was inadvertently omitted. This omission is being corrected to be consistent with the remainder of the rule and with our intent.

A typographical error appearing in § 60.758(c)(1)(ii) is being corrected. This section incorrectly references § 60.758(b)(3)(i) which does not exist. The correct reference is § 60.758(b)(3).

IV. Administrative Requirements

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and is therefore not subject to review by the Office of Management and Budget. Because the EPA has made a “good cause” finding that this action is not subject to notice and comment requirements under the Administrative Procedure Act or any other statute (see Start Printed Page 18908Summary), it is not subject to the regulatory flexibility provisions of the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), or to sections 202 and 205 of the Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4). In addition, this action does not significantly or uniquely affect small governments or impose a significant intergovernmental mandate as described in sections 203 and 204 of UMRA. This rule also does not significantly or uniquely affect the communities of tribal governments, as specified by Executive Order 13084 (63 FR 27655, May 10, 1998). This rule does not have substantial direct effects on the States, on the relationship between the national government and the States, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This rule also is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997), because it is not economically significant.

This technical correction action does not involve technical standards; 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. The rule also does not involve special consideration of environmental justice related issues as required by Executive Order 12898 (59 FR 7629, February 16, 1994). In issuing this rule, the EPA has taken the necessary steps to eliminate drafting errors and ambiguity, minimize potential litigation, and provide a clear legal standard for affected conduct, as required by section 3 of Executive Order 12988 (61 FR 4729, February 7, 1996). The EPA has complied with Executive Order 12630 (53 FR 8859, March 15, 1988) by examining the takings implications of the rule in accordance with the “Attorney General's Supplemental Guidelines for the Evaluation of Risk and Avoidance of Unanticipated Takings' issued under the executive order. 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 EPA's compliance with these statutes and Executive Orders for the underlying rule is discussed in the June 16, 1998 amendments to the final NSPS/EG rule Federal Register document.

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. Section 808 allows the issuing agency to make a rule effective sooner than otherwise provided by the Congressional Review Act if the agency makes a good cause finding that notice and public procedure is impracticable, unnecessary or contrary to the public interest. This determination must be supported by a brief statement (5 U.S.C. 808(2)). As stated previously, the EPA has made such a good cause finding, including the reasons therefor, and established an effective date of April 10, 2000. The 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. This action is not a “major rule” as defined by 5 U.S.C. 804(2).

MNMOC = 2Lo R (e−kc−e−kt) CNMOC (3.6 × 10−9)
