W. maintenance procedures are utilized to assure the structure's performance. In WS =III and WS -IV watersheds, local governments may choose to allow higher density development with the utilization of engineered stormwater control structures. However, in these cases local governments must assume the ultimate responsibility for the operation and maintenance of these stormwater control structures. Where these structures aze used, a number of national studies have shown that wet detention ponds are the most effective devices in addressing water quality problems associated with stormwater runoff. As additional information becomes available, DEM will review these requirements to determine if other alternative controls will provide similar levels of protection. If this proves to be the case, more flexibility can be added to.the rules to allow alternative designs. At this time, however, DEM feels that wet detention ponds are the most appropriate form of stormwater control when such engineered structures are required. A number of allowable land use practices are also addressed in the adopted rules. New sites for the land application of sludge materials and new landfills are allowed outside the critical areas of WS -II, WS -III and WS -IV watersheds. In some instances - critical areas of WS -II and WS -III watersheds - new non - residential development in the form of industrial facilities is restricted. In dealing with the issue of the use, storage or production of hazardous materials, these rules address these issues by requiring local authorities to maintain inventories of materials of this type in the.watershed and also to develop plans to deal with potential spill situations. Information Under Consideration at These Hearings The EMC, at their May 9, 1991 Commission meeting, approved proposed water supply watershed classifications to be taken to public hearing. These classifications will allow all existing surface waters.used for water supply purposes to be reclassified to their most appropriate classification under the recently adopted water supply classifications and rules. Also, through review by staff, a few new issues have been addressed and are proposed for modification to the adopted rules. These modifications are also under consideration during this hearing process. In addition, the EMC and DEM feel that these hearings offer a good.opportunity to receive additional comments on those areas of the rules that were changed during the last hearing process. WREN CONSIDERING THE INFORMATION AT ISSUE, IT SHOULD BE CLARIFIED THAT THE COMMISSION CAN ADOPT RULES AND CLASSIFICATIONS THAT ARE MORE OR LESS STRINGENT THAN THOSE PROPOSED IF THE EMC DETERMINES THAT THE PROVISIONS ADOPTED ARE A LOGICAL OUTGROWTH OF THE PROPOSED CRITERIA AND THE INFORMATION RECEIVED DURING THE HEARING PROCESS. FOR THIS REASON IT IS IMPORTANT THAT YOU COMMENT ON AREAS YOU WOULD LIKE TO SEE REMAIN THE SAME OR BECOME MORE STRINGENT AS WELL AS THOSE THAT YOU FEEL SHOULD BECOME MORE FLEXIBLE. IT SHOULD ALSO BE NOTED THAT MODIFICATIONS TO THE FINAL RULES OR CLASSIFICATIONS-COULD POTENTIALLY AFFECT PERSONS WHO ARE 3
