ADVISORY BOARD RECOMMENDATION

     At the March 1972 International Joint Commission (IJC)  Lakes Advisory

Board (now the IJC Great Lakes Board), a recommendation was  made that the

Ontario Ministry of the Environment (Ontario MOE),  the Michigan Water

Resources Commission (MWRC), and the U.S. Environmental Protection Agency,

Michigan District Office (EPA-MIDO) meet to discuss the causes of high

coliform densities in the Detroit River.  The meeting was held at the

EPA-MIDO office on April 25, 1972, with representatives from the three

agencies present.


COLIFORM DATA ANALYSIS

     Because sewage treatment plant effluents generally receive adequate

disinfection, the agencies hypothesized that the present condition is

being caused by combined sewer overflows during rainstorms.   To test this

hypothesis, the 1971 coliform data were grouped according to whether the

sample was collected during (or five days after a 0.2 inch/day rain) or

during a dry period.  The median of each group was  determined.  These are

listed in Attachment 1.  It can be seen without Vigorous statistical

analysis that the wet weather densities exceed the  dry weather densities

at almost every river station.


COMBINED SEWERS

Locations

     Attachment No. 2 lists the locations of stormwater outlets in the

Detroit area.  Attachment No.  3 is a map of these locations.  This

Waters of Lake Erie, and Their Tributaries, U.S. DHEW, PHS, April 1965.






ABATEMENT PROGRAMS




     Recommendations of the Detroit River and Lake Erie Enforcement




Conferences and requirements of the Federally-approved interstate water




quality standards require control and treatment of combined sewer overflows.




     The City of Detroit is under orders from the MWRC to study methods of




control and to reduce volume and frequency of combined sewer discharges.




     In 1966, the Detroit Metropolitan Water Department received a research




and development grant from the Federal Government to develop a system to




monitor and control stormwater overflows.  The Water Department developed




a telemetering system which measures rainfall, gate openings, and the




level of stormwater in each section of the interceptor system.  The levels




and storage can be controlled from a central location by adjusting gates




and pump operation in the system.  Bypassing of stormwater to the Detroit




River is minimized by routing more water through the treatment plant.




The system to date has significantly reduced the effect of combined sewer




overflows and the Water Department continues to improve the system.




     Other controls on the United States side of the Detroit River include:




     1)  Construction to improve the Fox Creek interceptor and eliminate




     bypasses from this location has begun.




     2)  The City of Trenton completed its sewer separation program




     in 1969.




     3)  The Ecorse Creek drainage area communities including all or parts

-------
of:  River Rouge, Ecorse, Lincoln Park, Taylor, Allen Park, Southgate,




Dearborn Heights, and Wyandotte are under MWRC orders to solve their




problem by January 1, 1975.  To date, preliminary planning phases




have been completed.




4)  A plan for relief drain No. 5 drainage area, including parts of




Wyandotte and Southgate, has been developed whereby stormwater will




receive a minimum of one hour retention with chlorination.




5)  The possibility of improving the situation at Conners Creek is




being studied.




6)  Communities draining to the Milk River and Nine Mile Road relief




sewer discharging to Lake St. Clair have begun an action program




under MWRC guidelines to solve their problems.
