(2) There may
				  be no discharge allowance for process wastewater pollutants from any battery
				  manufacturing operation other than those battery manufacturing operations
				  listed in tables 72 to 80.
(3) In
				  cases where battery employe shower wastewater containing concentrations of lead
				  exceeding 0.20 mg/l is combined with process wastewaters prior to treatment,
				  the control authority may, under and notwithstanding the provisions of s.
				  NR 211.12,
				  exercise its discretion and classify battery employe shower wastewater as an
				  unregulated rather than a dilute (FD) wastestream, for the purpose of applying
				  the combined wastestream formula. Before the control authority may exercise its
				  discretion to classify such a stream as an unregulated stream, the battery
				  manufacturer must provide engineering, production, and sampling and analysis
				  information sufficient to allow a determination by the control authority on how
				  the stream should be classified.
