A. A 3.05 General Permit allows discharges of
reclaimed water into constructed or natural wetlands, including waters of the
United States, waters of the state, and riparian areas, for disposal. This
general permit does not apply if the purpose of the wetlands is to provide
treatment.

Discharge. In addition to the Notice of Intent to Discharge requirements
specified in
R18-9-A301(B),
an applicant shall submit the name and individual permit number of the facility
providing the reclaimed water.
C.
Design requirements. An applicant shall:
1.
Ensure that the reclaimed water released into the wetland meets numeric and
narrative Aquifer Water Quality Standards for all parameters except for
coliform bacteria and is Class A+ reclaimed water. A+ reclaimed water is
wastewater that has undergone secondary treatment established under
R18-9-B204(B)(1),
filtration, and meets a total nitrogen concentration under
R18-9-B204(B)(3)
and fecal coliform limits under
R18-9-B204(B)(4);
2. Maintain a minimum horizontal separation
of 100 feet between any water supply well and the maximum wetted area of the
wetland;
3. Post signs at points of
access and every 250 feet along the perimeter of the wetland stating, "CAUTION.
THESE WETLANDS CONTAIN RECLAIMED WATER. DO NOT DRINK." The applicant shall
ensure that the signs are in English and Spanish, or in English with inclusion
of the international "do not drink" symbol; and
4. Ensure that wetland siting is consistent
with local zoning and land use requirements.
D. Operational requirements.
1. A permittee shall manage the wetland to
minimize vector problems.
2. The
permittee shall submit to the Department and implement a Best Management
Practices Plan for operation of the wetland. The Best Management Practices Plan
shall include:
a. A site plan showing the
wetland footprint, point of inflow, stormwater drainage, and placement of
vegetation;
b. Management of flows
into and through the wetland to minimize erosion and damage to
vegetation;
c. Management of
visitation and use of the wetlands by the public;
d. A management plan for vector
control;
e. A plan or criteria for
enhancing or supplementing of wetland vegetation; and
f. Management of shallow groundwater
conditions on existing on-site wastewater treatment facilities.
3. The permittee shall perform
quarterly inspections to review bank integrity, erosion evidence, the condition
of signage and vegetation, and correct any problem noted.
E. Recordkeeping. A permittee shall maintain
the following information for at least 10 years and make it available to the
Department upon request:
1. Construction
drawings and as-built plans, if available; and
2. A log book or similar documentation to
record inspection results, repair and maintenance activities, monitoring
results, and facility closure.
F. Reporting requirements. The permittee
shall, by January 30, provide the Department in writing with an annual
assessment of the biological condition of the wetland, including the volume of
inflow to the wetland in the past year.
