No user shall discharge any substance directly into a manhole, clean out or other opening in a sanitary sewer other than through an approved building sewer, unless upon written application by the user and payment of the applicable user charges and fees, the city issues a permit for such direct discharges.

No person shall discharge any holding tank wastes, or wastes from barrels, storage tanks or any other such containers not directly connected to the city sewer unless the user has obtained a special discharge permit. Unless otherwise allowed by the city, under the terms and conditions of the special discharge permit, a separate permit must be secured for each separate discharge. The user may be required to sample, analyze and report to the city the characteristics of the waste, prior to the issuance of the permit. The permit may stipulate the specific location of the discharge, the time of day the discharge is to occur, limits of the volume discharged and the constituents and characteristics of the waste. The user shall pay all applicable charges and fees and shall meet such other conditions as required by the city. (Ord. 2282 NCS §3 (part), 2007.)
