| (D) Disposal of wastes from boats or any other watercraft
shall be in accordance with §§321.1 - 321.11 of this title
(relating to Boat Sewage Disposal).
(E) Pesticides or herbicides which are used within
the watershed shall be applied in strict accordance with the product
label restrictions.
(F) Before approval of a new surface water source,
the system shall provide the executive director with information regarding
specific water quality parameters of the potential source water. These
parameters are pH, total coliform, Escherichia
coli, turbidity, alkalinity, hardness, bromide, total organic
carbon, temperature, color, taste and odor, regulated volatile organic
compounds, regulated synthetic organic compounds, regulated inorganic
compounds, and possible sources of contamination. If data on the incidence
of Giardia cysts and Cryptosporidium oocysts has been collected,
the information shall be provided to the executive director. This
data shall be provided to the executive director as part of the approval
process for a new surface water source.
(G) All systems with new surface water intakes or new
bank filtration wells must monitor microbiological source water quality
at the new surface water intakes or new bank filtration wells in accordance
with §290.111 of this title on a schedule determined by the executive
director. The system must notify the agency of the new surface water
intake or bank filtration well prior to construction.
(2) Intakes shall be located and constructed in a manner
which will secure raw water of the best quality available from the
source.
(A) Intakes shall not be located in areas subject to
excessive siltation or in areas subject to receiving immediate runoff
from wooded sloughs or swamps.
(B) Raw water intakes shall not be located within 1,000
feet of boat launching ramps, marinas, docks, or floating fishing
piers which are accessible by the public.
(C) A restricted zone of 200 feet radius from the raw
water intake works shall be established and all recreational activities
and trespassing shall be prohibited in this area. Regulations governing
this zone shall be in the city ordinances or the rules and regulations
promulgated by a water district or similar regulatory agency. The
restricted zone shall be designated with signs recounting these restrictions.
The signs shall be maintained in plain view of the public and shall
be visible from all parts of the restricted area. In addition, special
buoys may be required as deemed necessary by the executive director.
Provisions shall be made for the strict enforcement of such ordinances
or regulations.
(D) Commission staff shall make an on-site evaluation
of any proposed raw water intake location. The evaluation must be
requested prior to final design and must be supported by preliminary
design drawings. Once the final intake location has been selected,
the executive director shall be furnished with an original or legible
copy of a United States Geological Survey 7.5-minute topographic quadrangle
showing the accurate intake location.
(E) Intakes shall be located and constructed in a manner
which will allow raw water to be taken from a variety of depths and
which will permit withdrawal of water when reservoir levels are very
low. Fixed level intakes are acceptable if water quality data is available
to establish that the effect on raw water quality will be minimal.
(F) Water intake works shall be provided with screens
or grates to minimize the amount of debris entering the plant.
(G) Intakes shall not be located within 500 feet of
a sewage treatment plant or lands irrigated with sewage effluent.
(3) The raw water pump station shall be located in
a well-drained area and shall be designed to remain in operation during
flood events.
(4) An all weather road shall be provided to the raw
water pump station.
(5) The raw water pump station and all appurtenances
must be installed in a lockable building that is designed to prevent
intruder access or enclosed by an intruder-resistant fence with lockable
gates.
