Section NR 270.054 - New source performance standards (NSPS)

Except as provided in ss. NR 270.0015, 270.002 and 270.003, any new source subject to this subcategory shall achieve the following NSPS representing the degree of effluent reduction attainable by the application of the best available demonstrated technology (BADT):

(1) The concentration of pollutants discharged in mine drainage from mines obtaining titanium ores from lode deposits may not exceed:

Effluent characteristic	[NSPS] Effluent limitations
	Maximum for any 1 day	Average of daily values for 30 consecutive days
Milligrams per liter
TSS	30.0	20.0
Fe	2.0	1.0
pH	(1)	(1)

(2) The concentration of pollutants discharged from mills beneficiating titanium ores by electrostatic methods, magnetic and physical methods, or flotation methods may not exceed:

[NSPS] Effluent limitations
Average of daily values
Effluent characteristic	Maximum for any 1 day	for 30 consecutive days
Milligrams per liter
TSS	30.0	20.0
Zn	1.0	0.5
pH	(1)	(1)

(3) The concentration of pollutants discharged in mine drainage from mines engaged in the dredge mining of placer deposits of sands containing rutile, ilmenite, leucoxene, monazite, or zircon and the milling techniques employed in conjunction with the dredge mining activity (milling techniques employed include the use of wet gravity methods in conjunction with electrostatic or magnetic methods) may not exceed:

Effluent characteristic	[NSPS] Effluent limitations
	Maximum for any 1 day	Average of daily values for 30 consecutive days
Milligrams per liter
TSS	30.0	20.0
Fe	2.0	1.0
pH	(1)	(1)

¹ Within the range 6.0 to 9.0
