I I COLORADO WATER CONSERVATION BOARD MEETING MINUTES Room 320E, State Capitol Denver, Colorado December 12, 1973 The meeting was called to order by Mr. Stapleton, Chairman, at 10:10 a.m. Mr. Stapleton: We will call this regularly scheduled meeting of the Colorado Water Conservation Board to order. The first item on the agenda is the approval of the minutes of the board meeting of August 14, which have been furnished the board. Are there any additions or corrections to the minutes as submitted? If not, I will entertain a motion that those minutes be approved. Mr. williams: I so move. Mr. Ford: I will second it. Mr. Stapleton: It has been regularly moved and seconded. All those in favor signify by saying "aye" - opposed, "no." The minutes are approved. Let's go to number 2 on the agenda - proposed EPA regulation to establish salinity standards for the Colorado River. We have been having a lot of action on this matter since the last board meeting. We got a memorandum from Larry on this. Will you start the dis- cussion, please. ~tt. Sparks: We mailed to the board members the preliminary regula- tion of the Environmental Protection Agency which proposes to estab- lish salinity standards on the Colorado River. The proposed regula- tion would establish salinity standards on the Colorado River to maintain the salinity as of April 19, 1972. The proposed regulation does not set forth the actual salinity count which existed as of April 19, 1972, nor does it specify the specific point on the lower Colorado River. However, from the background information, we assume that the point on the lower river that the standards refer to is Imperial Dam and that the salinity as of April 19, 1972, means about 850 parts per million of total dissolved solids. Whether or not this is correct we don't know. Our interpretation is based upon the agreement between the United States and the Republic of Mexico as contained in the Minute 242, which was also sent to the board members.
