(d) The completion of each charging procedure, including sweeping excess coal into the oven just charged, as quickly as possible.
NR 415.08(3)
(3) Fugitive emissions from pushing operations shall be captured by a traveling hood and controlled to not more than 0.080 pounds of particulate matter per 1000 pounds of exhaust gas. Any emissions escaping capture may not exceed 20% opacity for each pushing operation, as determined by the average of 6 consecutive observations made at 15 second intervals.
NR 415.08(4)
(4) There may be no visible emissions from 90% of the doors of all coke ovens in use; 95% of all coke oven charging port lids on ovens in use; and 90% of all offtake piping on ovens in use, except those open for charging, pushing, cleaning and maintenance as determined by a one pass observation.
NR 415.08(5)
(5) Quench towers for the application of water on hot coke shall be equipped with grit arrestors or equivalent equipment approved by the department. Water used in quenching may not include coke by-product plant effluent, and total dissolved solids in make-up quenching water shall be less than 750 milligrams per liter.
NR 415.08(6)
(6) Coke oven combustion stacks may not emit more than 0.10 pounds of particulate matter per 1000 pounds of exhaust gas or have visible emissions greater than 20% opacity.

NR 415.09
NR 415.09 Compliance schedule for sources of condensible particulate matter. NR 415.09(1)(1)
General compliance schedule. If a source on which construction or modification was last commenced on or before July 1, 1975, other than a heatset web offset press, fails to meet a particulate emission limitation in this chapter because of the inclusion of condensible particulate matter, as defined in s.
NR 439.02 (4), in the determination of emission rates or concentrations, the owner or operator of the source shall achieve final compliance with the applicable limitation by October 1, 1990.
NR 415.09(2)
(2) Compliance schedule for heatset web offset presses. If a heatset web offset press on which construction or modification was last commenced on or before July 1, 1975 fails to meet a particulate emission limitation in this chapter because of the inclusion of condensible particulate matter, as defined in s.
NR 439.02 (4), in the determination of emission rates or concentrations, the owner or operator of the source may not exceed the following increments of progress in achieving compliance with that limit:
NR 415.09(2)(a)
(a) Submit plans for achieving compliance or request a variance in accordance with the provisions of sub.
(3) (a) by July 1, 1993.
NR 415.09(2)(c)
(c) Commence construction, installation or modification of any emission control system by December 31, 1994.
NR 415.09(2)(d)
(d) Complete construction, installation or modification of any emission control system by July 1, 1995.
NR 415.09(2)(e)
(e) Achieve final compliance with the applicable emission limit by December 31, 1995.
NR 415.09(3)
(3) Variance. Notwithstanding sub.
(2), the owner or operator of a source constructed or modified on or before July 1, 1975 which fails to meet a particulate emission limitation in this chapter because of the inclusion of condensible particulate matter, as defined in s.
NR 439.02 (4), in the determination of emission rates or concentrations may request in writing a variance from the emission limitation from the department under par.
(a) on or before July 1, 1993 if the source is a heatset web offset press.
NR 415.09(3)(a)
(a) The department may grant a variance under this paragraph and set an alternate emission limitation under the criteria and procedures outlined in s.
NR 436.05 (2) and

NR 415.09(3)(b)
(b) The department shall grant a variance under this paragraph and set an alternate emission limitation if the following criteria are met:
NR 415.09(3)(b)1.
1. The variance will not delay attainment or prevent maintenance of any ambient air quality standard, as determined by methods acceptable to the department.

2. The applicable particulate emission limitation for the air contaminant source for which a variance is requested was promulgated on or before October 1, 1987.

4. The air contaminant source for which a variance is requested is not reasonably capable of complying with the applicable emission limitation except by means of the installation and operation of an electrostatic precipitator, fabric filter baghouse or wet scrubber for particulates or the source is equipped with such a control device and demonstrates to the department's satisfaction that compliance is still not achievable.
