NOI Supplement for Type 3.06 General Aquifer Protection Permit
for Constructed Wetlands to Treat Acid Rock Drainage at Mining Sites [A.A.C. R18-9-D306]
This General Permit allows the operation of constructed wetlands for the treatment of acid rock drainage from a closed mining
facility. If the proposed discharge, design, or operation of the wetlands does not conform to this rule, the owner or operator must
obtain an individual APP.
Note: Please ensure that the narrative, design drawings, and any supplemental information provided is comprehensive and
adequate to demonstrate conformance with A.A.C. R18-9-D306.
1.
Please attach a narrative description and design plans for the facility to be addressed under this General Permit.
Describe wetland operations, the nature of the wetland, date and methods of construction, and identify all discharges to be
directed to the wetland. Please place a check in the following boxes indicating that you have provided all of the following
in the narrative.
Demonstration the wetland is designed for optimum size, cell configuration, vegetative species composition, and
berm configuration
Consideration of rainfall events, including how proper operation during a 25-year, 24 hour storm event will be
achieved and demonstration that physical integrity will be maintained during a100-year, 24-hour storm event
Details of the liner design, installation, and Quality Assurance/Quality Control procedures
Description of the quality of the influent, the treatment process to be used, and expected quality of the treated
wastewater
Characterization of the water released to the wetland, describing how it will be compatible with construction
materials and vegetation
