A letter of request for an Authorization to Construct was received December 5, 1990 by the
Division and final plans and specifications for the subject project have been reviewed and found to

approximately 160 sf of filter area, a 100,000 gpd carbon adsorption unit and a 75,000 gallon

This Authorization to Construct is issued in accordance with Part III paragraph A of

Management.
In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those as may be
required by this Division, such as the construction of additional or replacement wastewater
