Satisfactory resolution of all issu es is expected in 1977. The plant's location is particularly attractive, especially from a water pollution viewpoint. Ultim ate discharge into the M ississippi River of plant w astew aters and a future Regional M unicipal W aste.Treatm ent Plant should serve to m inim ize water pollution requirem ents. The plant should be a priority location for the placem ent of new p rocesses with high dissolved solids in their discharges. Air pollution requirem ents w ill rem ain stringent as air quality for m ost designated air pollutants is m arginally in com pliance. This should not be a constraint on site expansion.

This, coupled with present am bient air quality for hydrocarbons, could cause som e difficulty in obtaining approval for new construction. Favorable resolution of this issu e should be a m ajor result to be attained in 1977. The plant's relative open location and experience in handling chlorine m akes it a prim e site for future chlorination p rocesses. Water Pollution Total plant discharge presently receives prim ary treatm ent at the Sauget Village Waste Treatm ent Plant. This system is being upgraded to a chem ical treatm ent facility with start-up com pletion scheduled for May, 1977. The plant and V illage are participating in a program to provide biological treatm ent Conahaorkeiag.ionIat lisb aasnitsicfioprattehde tChaitty soufchE aastsySstt.e mL owuiosualdndsaVtiisllfayg Me s oonfsaSnatuog'setloanngd term treatm ent n eed s.

U. S. C o a st G u ard Since the plant m oves "oils" across its barge docking fa cilities, it is subject to C oast Guard Spill requirem ents (33 CFR 153-6). Among the requirem ents are: a. preparation of a term inal operation manual; b. a dock fully equipped with spill containm ent equipm ent, or m em bersnip in an oil spill ciean-up cooperative. Oil sp ills carry a $5000 fine, in addition to tnat in No. 3 above. D. Effluents 1.

A rsenic Pretreatm ent standards for the discharge of arsenic from phos phorus trich lorid e production have been proposed by the U. S. EPA. Although they are not adopted yet, it is likely that they w ill be. At that tim e , a rsen ic rem o v a l fa c ilitie s w ill be required b efore ultim ate discharge. It has been shown that sufficient rem oval w ill occur in the- V illage ch e m ica l treatm en t plant. If standards are not m et, rem oval at the PCI3 and P^Sf departm ent w ill be required. 5. Phosphorus Elem ental phosphorus is receiving increased attention as a possible fish toxin. Indications also exist that it is bio-accum ulated. The plant has the potential to discharge elem ental P from all phos phorus handling departm ents. Data on the presence or absence of P in the discharge need to be obtained. P retreatm ent standards for P w ill lik e ly be e sta b lish e d for P C l^ , F g S g , an<* POCI3 in 1977. 6. P retrea tm en t/T o x ic P ollutan ts - * EPA may adopt regulations requiring source pretreatm ent of EPA designated toxic pollutants. The extent of pretreatm ent for organic m aterials may be dependent upon the biodegradability of the sub stance in a m unicipal regional treatm ent system . EPA has targeted 224 inorganic and organic compounds and fam ilies of compounds for initial coverage of th ese, 23 are p ossib ly p resent in the total plant discharge. These are item ized in Table 7. Internal cap abilities to m onitor for these sp ecific compounds are not developed yet. TABLE 7. EPA DESIGNATED TOXIC POLLUTANTS IN W. G.

The available benzene data indicate com pliance with the existing lim it but a 1 ppm standard would be exceeded. The im pact of this change should be determ ined. 7.
