• <br />Salinity <br />Regulation 3.10.0, Regulations Eor Implementation of the Colorado River <br />Salinity Standards Through the Colorado Discharge Permit Program, addresses the <br />discharge of salinity to the Colorado River Basia. <br />It is a requiremeat of the regulation that the salinity of each discharge <br />in the Colorado River Basin be evaluated for .impact on Che system. Generally, <br />the net impact on salinity to the basin from the sand and gravel production is <br />negligible because the waters are typically shallow groundwaters which <br />eventually reach the river. Nonetheless, the state reserves the right to <br />refuse the applicability under the general discharge permit of any sand and <br />gravel operation, 1f it appears chat the discharge will not be consistent with <br />regulations. Additionally, quarterly monitoring for salinity will be a permit <br />requirement for all facilities located in the Colorado River Basin. Should the <br />data identify a problem the state will have the right co require the facility <br />to obtain an individual permit, whereby a study addressing the economic <br />Feasibility of salt removal can be required. <br />Spill Prevention <br />As most facilities provide bulk storage of same volume of petroleum <br />products or other chemicals, the permit will require adequate protection of <br />such facilities sa as co prevent loss of these materials into discharged <br />eaters. Such protection can cake various forms, however diking in most cases <br />will prove to be the most cost effective. This provision Ss required as the <br />Division interprets proper operation, as properly addressing potential <br />pollutant sources before problems occur. <br />Settling agents <br />Because of the vide variety of available chemical flocculants, the use of <br />such settling aids must be subject co prior approval by the permitting <br />authority. However, since lime and alum are [he most Frequently used aids Eor <br />settling and typically their use results in no significant effect on other <br />pollutant parameters, permission Eor such use will not be required. No <br />specific limitations on the approved flocculanc agents has historically been <br />necessary to assure their proper use. Lf over application of a Elocculant <br />appears co be a problem, revocation of the general permit discharge authority <br />may be warranted. <br />- 5 <br />
