G. Everist, Inc. Again, I will number my answers in the same order as your questions in the letter. <br />A(1). In the information we faxed to you on October 21, we noted the ]00 year flood plain of <br />Maryland Creek. <br />B(2). The applicant commits to submitting a Technical Revision describing the construction plans, <br />alignment, and sizing of the augmentation pond prior to the pond being lined. <br />C(1). The applicant commits to adding a test for oil and grease onto the list of quarterly <br />groundwater testing parameters. <br />D(2). Also, in our fax submittal to you we included details on the size and location of the proposed <br />spillways. The scale on the exhibit showing the two detention ponds and spillways is l "=200'. <br />The detention ponds were sized to handle the 100-year event. The spillways will, therefore, <br />only be used for events greater than the 100-year. The 2.3 acre-feet detention ponds will, <br />therefore, handle both the 10-year and 100-year events. <br />
