Applicability; description of the cold forming subcategory. NR 254.10(1)
(1) This subchapter applies to the discharge of pollutants to waters of the state and the introduction of pollutants into POTWs from cold rolling and cold working pipe and tube operations in which unheated steel is passed through rolls or otherwise processed to reduce its thickness, to produce a smooth surface, or to develop controlled mechanical properties in the steel.
NR 254.10(2)
(2) The limitations and standards set forth in
ss. NR 254.102 to
254.107 for cold worked pipe and tube operations shall be applicable only when cold worked pipe and tube wastewaters are discharged at steel plant sites. No limitations are applicable or allowable when these wastewaters are hauled off-site for disposal or are otherwise not discharged at steel plant sites. The limitations and standards set forth in
ss. NR 254.102 to
254.107 for cold worked pipe and tube operations shall be applicable only to the blowdown of soluble oil or water solutions used in cold worked pipe and tube forming operations. Limitations for other wastewater sources from these operations shall be established on a site specific basis.
