Hansen & Associates for Testing ~f the NPDES Pervious Concrete Pilot Project Report by: Public Works Director Lee Thompson EXHIBITS ATTACHED: Agreement RECO~%~ENDATION: ~Approve Agreement and authorize Mayor to sign for the City FINANCIAL STATEMENT: The cost of testing services is on a time and materials basis not to exceed $4,950 and will be reimbursed by the Alameda County Clean Water Program. DESCRIPTION: As part of the local program of the National Pollution Discharge Elimination System (NPDES), Dublin has undertaken a pilot project at the Shannon Center parking lot to clean storm waters from the parking lot before the water can contaminate downstream creeks. The construction of this pilot project has been completed, as has base-line contaminant testing of the stormwaters flowing from the parking lot. The last phase of the work is to now test the completed improvements to see if significant pollutants are, in fact, being filtered out. If this project is successful, then similar projects may be used in new construction where there is the propensity for pollutant runoff, such as from gas stations. The consulting firm being recommended is already doing pollutant load monitoring for other NPDES projects in Alameda County and is very familiar with the program. The scope of the control testing will include "spiking" water with pollutants similar to those found in previous field tests of runoff from the parking lot and passing this water through the filtering system. Water will then be picked up at the pipe outlet and tested for pollutant loading. Once the testing has been completed, the City will write a final report for the project explaining the process and the results of the testing. Staff recommends that the City Council approve this agreement for consulting services and authorize the Mayor to sign the agreement for the City. a:(NPDES)~94-1~agstagmt ITEM NO. ~ COPIES TO: S.R.

HANSEN & Associates Environmental Consulting December 15, 1993 Mr. Mehran Sepehri Senior Civil Engineer City of Dublin 100 CMc Plaza Dublin, California 94568 Dear Mehran: In response to your request, S.R. Hansen & Associates (SRH&A) is please to submit this letter proposal for the performance of a study to evaluate the ability of the "concrete cover and sand bed system" (i.e., system) to treat stormwater runoff from the parldng lot in Shannon Park. Overview Conceptually, there are two ways to approach this issue. These can be described as follows: 1. Controlled Experiments - In this approach, clean water would be spiked with a variety of contaminants (concentrations based on prior data from site) and passed through the system. At set intervals, samples of water leaving the system would be collected and analyzed for the spiked analytes. The results generated would provide a quantified estimate of the effectiveness of the treatment for each of the contaminants added. The advantage of this approach is that we have excellent estimates of what is going into the system and can gain some insight into break- through characteristics. The disadvantage is that this is a simulation of reality as opposed to the real thing. 2. Stormwater Monitoring - In this approach, an actual storm event would be monitored. Samples entering the system and ex/ting the system would be collected a set time periods and analyzed for a selected number of contaminants. The results generated would generate an estimate of the effectiveness of the the system to remove each of the contaminants throughout the storm event. Probably emphasis on sampling and analysis would be made during the early:part of the storm when contaminant concentrations would be expected to be the highest. The advantage of this approach is that an actual storm event is being evaluated and the dynamics over the course of the storm can be considered. The disadvantages include varying input concentrations over time (perhaps no contaminants would be present), problems in influent collection, and the possibility of missing the start of the runoff due to the unpredictability of storm initiation. 4085 Nelson Avenue, Suite I · Concord, CA 94520 · (510) 687-5400 · Fox (510) 687-2296 M. Sepehri Page 2 Proposed Approach If sufficient funds were available, we would propose that a combination of the two approaches be used. First, controlled experiments would be performed to evaluate the theoretical effectiveness of the system. Second, actual runoff monitoring would be performed to confirm what the controlled experiments predicted. However, due to the limited funds available, we propose that the controlled experiments would be the most advantageous. In the controlled experiment, 400 gallons of distilled water or Dublin-San Ramon Service District Water (depending upon chemical composition) would be spiked with concentrations of oil & grease, chromium, copper, lead, nickel, and zinc. The concentrations of the spikes would be based on concentrations previously measured in stormwater runoff from the site. For 30 minutes, dean water (unspiked distilled water) would be passed through the system to eatablish a water quality baseline. Following this baseline period, spiked water would then be passed through the system to simulate runoff from a 0.5 inch storm for aproximately 3 hours. Samples leaving the treatment system would be collected at the endpoint of the baseline period, after the first five minutes of spiking, and every 30 minutes thereafter. Each sample (total of 8) would be analyzed for each of the spiked constituents. Estimated Cost Equipment & Supplies Water = $ 550 Tanks = 600 Miscellaneous = 300 Personnel 32hrs @ $40/hr = 1,280 Chemical Analysis $200/sample X 8 samples = 1,600 Data Analysis & Report Preparation = 620 Total $ 4,950 Food for Thought It should be noted that we feel it unlikely that the sand barrier will provide a good medium for sorption of organics and/or heavy metals. You might want to consider supplementing this layer with organic material (i.e., clay or activated carbon) prior to initiation of the study. If this proposal is acceptable to you, we will be prepared to initiate the experiments at your convenience. Sincerely, Step e~n R. Hansen, Ph.D. Principal EXHIBIT E PAYMENT SCHEDULE city shall pay Consultant an amount not to exceed the total sum of Four Thousand Nine Hundred-Fifty Dollars ($4,950) for services to be performed pursuant to this Agreement.
