Edmonds, Washington, 98020 Dear Bob: Bill Mac Donald 702 Puget Lane Edmonds, Wn., 98020 December 1, 1991 R E C E 11V DEC 5 Thanks for your letter of November Ist, and I apologize for the delayed reply, but was kind of laid up for a while. I have lately had the chance to check the Shell Creek outfall and it seems to be flowing fine at this time. Even though we have had some fairly heavy rains, the pipe is still about 1/2 full of gravel and sand, but the water is flowing and the stench is gone. I would assume it is gone for the winter, but we will have to face it again in the spring. I looked at the profile of the beach by the outfall, and think that it would take about 30-401 of additional pipe to get it out to where the tide would not fill it with sand and gravel. It might still not be entirely clear at all times, but it would be close I think. However, just from looking at it, I suggest we pursue the idea put out at the meeting, to install a smaller pipe out from the base of the larger outfall pipe. I would suggest a pipe about 12-1811 in diameter, which would not be an obstruction on the beach, as it would be completely buried for most of it's length, and exposed only at the end. Also, by putting a baffle in the end of the larger pipe up to about 2/3 of the diameter, and letting the smaller pipe issue from the bottom of the baffle, it would keep most of the infusion of seaweed, etc. out of the pipe and still let it drain. I think it would still provide for plenty of drainage, even in the heaviest of rains. By using the smaller pipe, it would keep the cost to a minimum and also minimize the obstruction on the beach,. It would be important to check the topography of the beach at that point carefully to make sure, but I think it might work, as long as the upper 1/3 of the large pipe that is open is above high'tide line, so sand, gravel, seaweed, and driftwood don't get washed into the pipe at extreme high tides. Please let me know if this makes sense, and maybe we can meet to look into this again sometime after the Holidays. I would be glad to meet you at the beach sometime, if that would work for you so we could check this out. Have a Happy Holiday Season!!!!

Janan M E M 0 R A N D U M October 30, 1991 TO: File ElHA Shell Creek Outfall FROM: R. J. Alberts, City Engineer SUBJECT: MEETING REGARDING OUTFALL ODORS On October 29, 1991, Mr. Lloyd Ostrom,,Mr. Bill MacDonald, Jim Walker, and Bob Alberts met to discuss odor problems at the outfall pipeline. The group concurred the problem was most likely due to decaying seaweed in the pipe. During high tides, the pipe is filled with the salt water and organics in the water. The high tides also push the beach sand over the outlet of the pipe preventing the water from escaping and flushing the pipe during low tides. The water sits in the pipe and the organics decay, thus producing the odor. It was also noted at the meeting that the air in the pipe above the water was very stagnant, and there was no air movement. Ideas discussed to try to correct the problem were: 1) Extend a smaller pipe (approximately 6 inches) out the end of the pipe into the tide flats. This would allow the water to escape from the pipe after high tides. The decaying of organic matter could still be a problem unless manually removed. 2) Pump the water out from the outlet of the pipe, and manually clean the pipe. 3) Install a screen to prevent the seaweed and other organic matter from entering the pipe. A concern was raised if the screen could open with the weight of any seaweed buildup on the screen. Another version of this idea was to install a split screen inside the pipe. 4) Chemical treatment. 5) Extend the outfall pipeline out into the tide flats. This would be expensive and make an obstruction on the beach. 6) Install an air exchange system such as air relief valves to circulate the air. 7) Install an air bubble system that would agitate the water and sand blocking the outlet. Enough agitation may be provided to flush the pipe. The group agreed the problem won't exist during the winter and plans need to be established to address the problem again in the summer. Memo to File ElHA Re: Shell Creek Outfall October 30, 1991 Page 2 Circulating the air appeared to be the first solution to try. Jim Walker would determine the volume of the standing water in the pipeline and take dissolved oxygen tests. The group would stay in contact.
