(i) If the target compound(s) is listed in Section 1.1 of ASTM D6420-99 and the target concentration is between 150 parts per billion by volume and 100 parts per million by volume.

(i) If the target compound(s) is listed in Section 1.1 of ASTM D6420-99 and the target concentration is between 150 parts per billion by volume and 100 parts per million by volume.

(i) The target compound(s) are those listed in section 1.1 of ASTM D6420-99 (Reapproved 2010) as measurable;

(A) The target compound(s) are those listed in section 1.1 of ASTM D6420-99 (2004);

(A) Except for authorities identified as not being delegated, the regulations incorporated in New Jersey's “Toxic Catastrophe Prevention Act Program,” Title 7, Chapter 31, of the New Jersey Administrative Code: Subchapter 1, “General Provisions” (sections 1.1 to 1.10 except for the definition of “What if Checklist”), Subchapter 2, “Hazard Assessment,” Subchapter 3, “Minimum Requirements for a Program 2 TCPA Risk Management Program,” Subchapter 4, “Minimum Requirements for a Program 3 TCPA Risk Management Program,” Subchapter 5, “Emergency Response,” Subchapter 6, “Extraordinarily Hazardous Substances,” Subchapter 7, “Risk Management Plan and TCPA Submission,” and Subchapter 8, “Other Federal Requirements,” (effective July 20, 1998), pertain to the sources affected by 40 CFR part 68 and have been approved under the procedures in §§ 63.91, 63.93 and 63.95 to be implemented and enforced in place of 40 CFR part 68, Subparts A through H, as may be amended.

(1) Authorities not delegated:

(i) The New Jersey Department of Environmental Protection is not delegated the Administrator's authority to implement and enforce New Jersey's Toxic Catastrophe Prevention Act Program, Title 7, Chapter 31, of the New Jersey Administrative Code, in lieu of the provisions of 40 CFR part 68 as they apply to the regulation of processes that are covered only because they contain regulated quantities of liquid petroleum gases (LPG) regulated under the New Jersey Liquified Petroleum Gas Act of 1950 (N.J.S.A. 21:1B),

(ii) Pursuant to § 63.90(c) the New Jersey Department of Environmental Protection is not delegated the Administrator's authority to add or delete substances from the list of substances established under section 112(r) and set forth in 40 CFR 68.130.

(D) To measure the total organic regulated material concentration at the outlet of a control device, use Method 18 of 40 CFR part 60, appendix A, or ASTM D6420-18 (incorporated by reference, see § 63.14). If you have a combustion control device, you must first determine which regulated material compounds are present in the inlet gas stream using process knowledge or the screening procedure described in Method 18. In conducting the performance test, analyze samples collected at the outlet of the combustion control device as specified in Method 18 or ASTM D6420-18 for the regulated material compounds present at the inlet of the control device. The method ASTM D6420-18 may be used only under the conditions specified in paragraphs (e)(2)(iii)(D)(1) through (3) of this section.

(1) If the target compounds are all known and are all listed in Section 1.1 of ASTM D6420-18 as measurable.

(2) ASTM D6420-18 may not be used for methane and ethane.

(3) ASTM D6420-18 may not be used as a total VOC method.
