The admission into the public sewers of any wastewaters having a five-day biochemical oxygen demand (BOD5) in excess of having two hundred fifty (250) mg/l by weight on a twenty-four (24)-hour composite sample basis, or, for any sample taken at random (grab sample), having a five-day biochemical oxygen demand (BOD5) in excess of three (3) times the average influent valve for the affected wastewater treatment facility during the previous calendar year, will be subject to review by the director. When, in the opinion of the director, discharge of wastewater into the public sewer system in strength exceeding the limits stated above may not be treatable at the publicly owned treatment works according to standards or as required by EPA/DEM, or when such discharge may interfere with the operation of the treatment works, the user shall, at his own expense, provide and operate pretreatment facilities and pretreat wastes to be discharged as may be required to meet the limits stated in this section. When the discharge of wastewater of strength exceeding these limits is permitted by the director, the user may, in addition to any other remedy, be assessed surcharge rates.
