§60.372. Standards for lead. — Inbound Citations

(b) The owner or operator shall determine compliance with the lead standards in § 60.372, except § 60.372(a)(4), as follows:

(1) Method 12 or Method 29 shall be used to determine the lead concentration (CPb) and, if applicable, the volumetric flow rate (Qsda) of the effluent gas. The sampling time and sample volume for each run shall be at least 60 minutes and 0.85 dscm (30 dscf).

(2) When different operations in a three-process operation facility are ducted to separate control devices, the lead emission concentration (C) from the facility shall be determined as follows:

(3) Method 9 and the procedures in § 60.11 shall be used to determine opacity. The opacity numbers shall be rounded off to the nearest whole percentage.

(e) Until February 23, 2026, lead acid battery manufacturing plant affected sources that commenced construction or reconstruction on or before February 23, 2023, must meet all the standards for lead and opacity in 40 CFR 60.372 and the requirements of § 63.11423(a)(1).

(i) You meet all the standards for lead and opacity in 40 CFR 60.372 and the requirements of paragraphs (a)(4) and (5), (b), and (c)(1) through (3) of this section.

(3) Method 9 and the procedures in § 60.11 shall be used to determine opacity. The opacity numbers shall be rounded off to the nearest whole percentage.

(iii) You must conduct a visible emissions observation at least once per day while the process is in operation to verify that no visible emissions are occurring at the discharge point to the atmosphere from any emissions source subject to the requirements of paragraph (a) of this section. If visible emissions are detected, you must record the incident and conduct an opacity measurement in accordance with 40 CFR 60.374(b)(3). You must record the results of each opacity measurement. If the measurement exceeds the applicable opacity standard in 40 CFR 60.372(a)(7) or (8), you must submit this information in an excess emissions report required under § 63.10(e)(3).
