1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall,
z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
4 See General Permit text, Table 3, identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
Note: Results must be reported in numerical format. For example, do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -
numerical format. When results are below the applicable limits, they must be reported in the format "<XX m L" where XX is the numerical value of the
detection limit, reporting limit, etc. in mg/L.
Note: if you report a sample value in excess of the benchmark, you must implement Tier 1, Tier 2, or Tier 3 responses. See General Permit text.

CONSTRUCTION SPECIFICATIONS
1. Clear, grub, and strip area of all vegetation and root
material. Remove all objectionable material.
2. Ensure fill material is free of objectionable material.
Place fill in 6" lifts and machine compact.
3. Protect connection between riprap and soil by using
filter fabric. Extend fabric across spillway foundation and
sides to top of dam.
4. Clear pond area below dam for sediment cleanout.
5. All cut and fill slopes should be 2:1 or flatter.
6. Ensure store section has min. bottom width of 3' with
max side slopes of 2: 1.
7. Ensure weir is level and constructed to grade.
8. Material used in stone section should be well-groded
mixture of stone with d50 size of 9" and max size of 14".
9. Ensure spillway extends past toe of embankment until
stable conditions are reached. Keep edges of stone outlet
flush with surrounding ground and shape center to confine
outlet stream.
10. Direct emergency bypass to natural, stable areas.
11. Stabilize embankment and all disturbed areas immed-
iately after construction, including embankment, emergency
spillway, above the sediment pool and downstream.
12. Mark cleanout level in field.

GENERAL NOTE5:
1. ONLY DISTURB CLEAR OR GRADE AREAS NECESSARY FOR CONSTRUCTION.
FLAG OR OTHERWISE DELINEATE AREAS NOT TO BE DISTURBED. EXCLUDE
VEHICLES AND CONSTRJCTION EQUIPMENT FROM THESE AREAS TO PRESERVE
NATURAL VEGETATION.
2. CLEAR AND GRUB AREAS TO BE FILLED TO REMOVE TREES, VEGETATION,
MUCK, ROOTS, OR OTHER OBJECTIONABLE MATERIAL THAT WOULD AFFECT
THE LANTED STABILITY OF THE FILL.
3. PLACE FILL IN LAYERS NOT TO EXCEED 6" IN THICKNESS AND COMPACT
THE LAYERS AS REQUIRED TO TO REDUCE EROSION, SLIPPAGE, SETTLEMENT,
OR OTHER RELATED PROBLEMS.
4. K7EP DIVERSIONS AND CHANNELS AND OTHER WATER CONVEYANCE
MEASURES FREE OF SEDIMENT AT ALL TIMES.
5. ROUGHEN THE SURFACE OF ALL SLOPES DURING THE CONSTRUCTION
OPERATION TO RETAIN WATER, INCREASE INFILTRATION, AND FACILITATE
VEGETATION ESTABLISHMENT.
6. PERMANENTLY STABILIZE ALL GRADED AREAS IMMEDIATELY AFTER FINAL
GRADING iS COMPLETED ON EACH AREA. APPLY TEMPORARY MEASURES ON
ALi GRADED AREAS WHEN WORK IS TO BE INTERRUPTED OR DELAYED FOR 15
WORKING DAYS OR 90 CALENDAR DAYS.
