Editorial Note: For Federal Register citations affecting §52.1167, see the List of CFR Sections Affected, which appears in the Finding Aids section of the printed volume and on GPO Access.

§ 52.1168 Certification of no sources.
top
The Commonwealth of Massachusetts has certified to the satisfaction of EPA that no sources are located in the Commonwealth which are covered by the following Control Techniques Guidelines:

(a) Large Petroleum Dry Cleaners.

(b) Natural Gas/Gasoline Processing Plants.

(c) Air Oxidation Processes/SOCMI.

(d) Polypropylene/Polyethylene Manufacturing.

§ 52.1168a Part D—Disapproval of Rules and Regulations.
top
On December 30, 1985, the Massachusetts Department of Environmental Quality Engineering (DEQE) submitted a revision to the Massachusetts State Implementation Plan (SIP) for the automobile surface coating regulation. This revision requested an extension of the final compliance dates to implement reasonably available control technology (RACT) on topcoat and final repair applications. As a result of EPA's disapproval of this revision, the existing compliance date of December 31, 1985 specified in the automobile surface coating regulation contained in the Massachusetts SIP will remain in effect (Massachusetts Regulation 310 CMR 7.18(7) as approved by EPA and codified at 40 CFR 52.1120(c)(30) and (53)).

[53 FR 36014, Sept. 16, 1988]

§ 52.1169 Stack height review.
top
The Commonwealth of Massachusetts has declared to the satisfaction of EPA that no existing emission limitations have been affected by stack height credits greater than good engineering practice or any other prohibited dispersion technique as defined in EPA's stack height regulations, as revised on July 8, 1985. This declaration was submitted to EPA on April 8, 1986. The commonwealth has further declared in a letter from Bruce K. Maillet, dated June 24, 1986, that, “[A]s part of our new source review activities under the Massachusetts SIP and our delegated PSD authority, the Department of Environmental Quality Engineering will follow EPA's stack height regulations, as revised in the Federal Register on July 8, 1985 (50 FR 27892).” Thus, the Commonwealth has satisfactorily demonstrated that its regulations meet 40 CFR 51.118 and 51.164.
