§ 58-86. Local limits.

(a)

To implement the general and specific discharge prohibitions listed in this division, industrial user-specific local limits will be developed ensuring that the POTW's maximum allowable headworks loading is not exceeded for particular pollutants of concern for each industrial user. Where specific local limits are not contained for a given parameter or pollutant in an industrial user permit, the following limits will apply to all users:

Limit (mg/l)	Pollutant
250	BOD
250	TSS
40	TKN
0.003	arsenic
0.003	cadmium
0.061	copper
0.041	cyanide
0.049	lead
0.0003	mercury
0.021	nickel
0.005	silver
0.05	total chromium
0.175	zinc

 

(b)

Industrial waste survey information will be used to develop user-specific local limits when necessary to ensure that the POTW's maximum allowable headworks loading is not exceeded for particular pollutants of concern. User-specific local limits for appropriate pollutants of concern shall be included in wastewater permits. The POTW director may impose mass limits in addition to or in place of concentration-based limits.
