NR 419.08 Core and mold manufacturing for iron or steel foundries. NR 419.08(1)(a)(a) This section applies to the manufacture of cores or molds for use at iron or steel foundries at any facility which is located in the county of Kenosha, Kewaunee, Manitowoc, Milwaukee, Ozaukee, Racine, Sheboygan, Washington or Waukesha.
NR 419.08(1)(b)1.
1. Iron or steel foundries or core manufacturing facilities which are located in the county of Kenosha, Milwaukee, Ozaukee, Racine, Washington or Waukesha which have maximum theoretical emissions of VOC from core and mold manufacturing of less than 25 tons per year.
NR 419.08(1)(b)2.
2. Iron or steel foundries or core manufacturing facilities which are located in the county of Kewaunee, Manitowoc or Sheboygan which have maximum theoretical emissions of VOC from core and mold manufacturing of less than 100 tons per year.
NR 419.08(1)(c)
(c) Any owner or operator of an iron or steel foundry or core manufacturing facility having annual emissions less than the applicability thresholds in par.
(b) shall comply with the recordkeeping requirements of sub.
(6) for that facility.
NR 419.08(2)
(2)
Emission and operational limitations. No owner or operator of a core or mold manufacturing system which produces cores or molds for use at iron or steel foundries may cause, allow or permit the operation of the system unless all of the following requirements are met:
NR 419.08(2)(a)
(a) The as applied VOC content of each core or mold coating, when measured using the methods contained in s.
NR 439.06 (3) (b), does not exceed any of the following limits:
NR 419.08(2)(a)1.
1. 30%, by weight, including water, for core or mold coatings which have an as purchased density of 15.0 pounds per gallon or greater.
NR 419.08(2)(a)2.
2. 70%, by weight, including water, for core or mold coatings which have an as purchased density of less than 15.0 pounds per gallon.
NR 419.08(2)(b)
(b) All core and mold coating storage vessels and containers remain covered whenever product is not being moved into or out of the vessel or container.
NR 419.08(2)(c)
(c) Emissions of the organic gases used in the catalysis step in the formation of urethane cold box binders are controlled with an overall efficiency of at least 90%.
NR 419.08(3)(a)
(a) Final compliance with the requirements of sub.
(2) shall be achieved by May 31, 1995 or upon startup, whichever is later.
NR 419.08(3)(b)

The owner or operator of any facility which uses a wet scrubber to control organic gas emissions from the catalysis of urethane cold box binders shall continuously measure and record the pH of the scrubber liquid in addition to meeting the monitoring requirements of s.
NR 439.055 (1) (e).
NR 419.08(6)
(6)
