Dear Annette:
?\ -0=3?5 ?
Please find the following additional information relating to the 401 Water Quality Certification for wetland and
stream impacts on the above mentioned project as requested in your email dated 9/6/2011. Enclosed in this
submittal is the following:
1. Construction plans, calculations and details of the existing sediment trap we are proposing to
treat the runoff from the roadway over the existing dam.
2. Construction plans, calculations and details for the roadway over the dam. Storm drainage
calculations are also included.
Note: The roadway over the dam and sediment trap has been constructed. The sediment trap has been
cleaned out and made fully operational as previously discussed in our correspondence.
Please advise if the submittal package is incomplete or if you need additional information. If you should have
any questions about the design, please do not hesitate to call for a clarification.
Sincerely,
944
