CONSTRUCTION COMPONENTS
B1 POTENTIAL POLLUTANT SOURCES: EXPECTED POLLUTANTS TO STORMWATER DURING CONSTRUCTION CAN BE BUT NOT LIMITED TO:
EXCESS SEDIMENT, ORGANIC MATERIALS SUCH AS LEAVES AND TWIGS, EXCESS CONCRETE, FUELS, BRAKE DUST, AND TRASH.
B2 STORMWATER QUALITY SEQUENCING:
PRE-CONSTRUCTION ACTIVITIES:
1. CALL THE INDIANA UNDERGROUND PLANT PROTECTION SYSTEM, INC. ("HOLEY MOLEY") AT 811 TO CHECK THE LOCATION OF ANY
EXISTING UTILITIES. THEY SHOULD BE NOTIFIED TWO WORKING DAYS BEFORE CONSTRUCTION TAKES PLACE.
2. ESTABLISH ONSITE LOCATION FOR OWNER/OPERATOR/CONTRACTOR PLACEMENT OF APPROVED PLANS AND EROSION CONTROL
MEASURE INSPECTION DOCUMENTS.

REMOVE THEM IMMEDIATELY.
CONSTRUCTION ACTIVITIES:
1. INSTALL APPROPRIATE PERIMETER PROTECTION AND INLET PROTECTION WHILE WORK IS BEING PERFORMED IN THE AREA.
CREATE STAGING AREA FOR MATERIALS. STOCKPILE AREA WILL NEED TO HAVE APPROPRIATE EROSION CONTROL PRIOR TO
CREATION. THESE EROSION CONTROL MEASURES ARE TO BE INSTALLED AS INDICATED ON PLAN SHEET 7 OF 18 (POND 10 ONLY).
2. POND CONSTRUCTION TO OCCUR. EXCAVATED POND WILL ACT AS SEDIMENT CONTROL DURING THE MASS GRADING PROCESS.
3. RESTORATION TO OCCUR FOR POND AND AREAS SHEET FLOWING TO THE POND. EROSION CONTROL ITEMS TO BE INSTALLED SUCH

STREET, AND E. 111TH STREET. THE CONTRACTOR SHALL MINIMIZE SEDIMENT TRACKING ONTO THE ROADWAY.
B4 SEDIMENT CONTROL MEASURES FOR SHEET FLOW AREAS INCLUDE BUT ARE NOT LIMITED TO: PERIMETER PROTECTION AND INLET
FILTERS.
B5 SEDIMENT CONTROL MEASURES FOR CONCENTRATED FLOW AREAS: LIMITED CONCENTRATED FLOWS FROM DEWATERING FOR
EXCAVATIONS WILL OCCUR DURING CONSTRUCTION. THE CONTRACTOR SHALL BE RESPONSIBLE FOR MINIMIZING SEDIMENTATION IN
THESE CONCENTRATED FLOWS, TYPICALLY AT DEWATERING PUMP DISCHARGES. OTHER SEDIMENT CONTROL PROCEDURES FOR OTHER
CONCENTRATED FLOWS, INCLUDING THOSE ASSOCIATED WITH WITH STAGING AREA RUNOFF, SHALL ALSO BE THE RESPONSIBILITY OF
THE CONTRACTOR.
B6 PROTECTION MEASURES FOR SURFACE INLETS CAN BE FOUND ON PLAN SHEETS 7 OF 18. DETAILS PERTAINING TO THESE EROSION
CONTROL MEASURES CAN BE FOUND ON SHEETS 17 AND 18.
2. REMOVE DEPOSITED SEDIMENT WHEN IT REACHES HALF THE HEIGHT OF THE PERIMETER PROTECTION AT ITS
LOWEST POINT, OR IS CAUSING THE PERIMETER PROTECTION TO BULGE.
3. TAKE CARE TO AVOID UNDERMINING THE PERIMETER PROTECTION DURING CLEAN OUT.
4. AFTER THE CONTRIBUTING DRAINAGE AREA HAS BEEN STABILIZED, REMOVE THE FENCE AND SEDIMENT
DEPOSITS, BRING THE DISTURBED AREA TO GRADE AND STABILIZE.
TEMPORARY SEEDING
1. INSPECT PERIODICALLY AFTER PLANTING TO SEE THAT VEGETATIVE STANDS ARE ADEQUATELY ESTABLISHED;
RE-SEED IF NECESSARY.
2. CHECK FOR EROSION DAMAGE AFTER STORM EVENTS AND REPAIR; RE-SEED AND MULCH IF NECESSARY.
3. TOP-DRESS FALL SEEDED WHEAT SEEDINGS WITH 50 LBS/ACRE OF NITROGEN IN FEBRUARY OR MARCH IF
NITROGEN DEFICIENCY IS APPARENT.
INLET PROTECTION

IMPEDES THE PASSAGE OF STORMWATER INTO THE SYSTEM.
2. INLET PROTECTION SHALL BE INSPECTED AND CLEANED AFTER EVERY RAIN EVENT, OR AT LEAST ONCE A WEEK.
CONCRETE WASHOUT AREA
1. INSPECT DAILY AND AFTER EACH STORM EVENT.
2. INSPECT THE INTEGRITY OF THE OVERALL STRUCTURE INCLUDING, WHERE APPLICABLE, THE CONTAINMENT
SYSTEM.
3. INSPECT THE SYSTEM FOR LEAKS, SPILLS, AND TRACKING OF SOIL BY EQUIPMENT.
4. INSPECT THE POLYETHYLENE LINING FOR FAILURE, INCLUDING TEARS AND PUNCTURES.
5. ONCE CONCRETE WASTE HARDENS, REMOVE AND DISPOSE OF MATERIAL.
6. EXCESS CONCRETE SHOULD BE REMOVED WHEN THE WASHOUT SYSTEM REACHES 50% CAPACITY.
7. THE POLYETHYLENE LINER SHOULD BE REPLACED AFTER THE REMOVAL OF CONCRETE WASTE.
B15 DOES NOT APPLY TO THIS PROJECT
POST-CONSTRUCTION COMPONENTS
C1 THE PROPOSED PROJECT IS A STORM SEWER INSTALLATION. POST CONSTRUCTION POLLUTANT EXPOSURE INCLUDE
THOSE PRODUCED BY VEHICULAR TRAFFIC SUCH AS: OIL, GREASE, ANTIFREEZE, BRAKE FLUID, BRAKE DUST, RUBBER
FRAGMENTS, DUST, GASOLINE, DIESEL FUEL, AND OTHER METALS AND FRAGMENTS FROM VEHICULAR SOURCES. OTHER
POLLUTANTS INCLUDE GRIT (SEDIMENT) FROM WEAR OF THE ROADWAY OR WASHING OFF VEHICLES AND TRASH FROM
LITTERING AND IMPROPER DISPOSAL OF WASTE.
C2 UNDERDRAINS WILL BE INSTALLED ALONG THE ALIGNMENTS OF HYBRID HITCHES. THE UNDERDRAIN PIPE SIZES RANGE
FROM 4" TO 18" AND WILL BE PERFORATED HDPE PIPE THAT WILL SERVE AS A CONVEYANCE ELEMENT AS WELL AS
COLLECTION POINT FOR INFILTRATIVE FLOWS. CLEAN STONE AND GEOMEMBRANE WILL BE INSTALLED ALONG THE
UNDERDRAINS TO ENHANCE INFILTRATION AND REDUCE PONDING SURFACE WATER. INLETS WILL BE INSTALLED ALONG THE
HYBRID DITCH SYSTEM AND ARE GENERALLY CONFIGURED TO PROVIDE MINOR PONDING PRIOR TO OVERTOPINIG INTO
INLETS IN ORDER TO FORCE INITIAL FLOWS TO INFILTRATE OR ENCOUNTER MICRO-PONDING PRIOR TO BEING COLLECTED
INTO THE STORMSEWER NETWORK. THE CONTRACTOR SHOULD FOLLOW THE GENERAL SEQUENCE BELOW:
1. EROSION AND SEDIMENT CONTROL PRACTICES FOR EACH HYBRID DITCH SECTION WILL NEED TO BE INSTALLED
AND MAINTAINED DURING THE COURSE OF CONSTRUCTION.
2. STORMWATER POLLUTION PREVENTION PRACTICES SHOULD BE REVIEWED AND MAINTAINED AS NEEDED TO KEEP
THEM EFFECTIVE. SEDIMENT WILL BE REMOVED FROM SEDIMENT CONTROL PRACTICES AND INLETS AFTER THE
SITE IS PERMANENTLY STABILIZED.
3. REVIEW ALL DISTURBED AREAS FOR FINAL STABILIZATION. A UNIFORM COVER OF 70% PERENNIAL VEGETATION
IS REQUIRED.
4. THE CONTRACTOR WILL REMOVE THE TEMPORARY EROSION OR SEDIMENT CONTROL PRACTICES AS THE
VEGETATIVE COVER FOR EACH PRACTICE IS PERMANENTLY STABILIZED.
5. SUBMIT THE NOTICE OF TERMINATION (NOT)
C3 POST CONSTRUCTION STORMWATER QUALITY MEASURES:
STORMWATER QUALITY MEASURES INCLUDE SEEDING, SODDING, AND MULCHING, ETC. ALL DENUDED AREAS NOT PAVED
WILL BE RE-VEGETATED. ALL PAVED AREAS WILL BE KEPT FREE OF LITTER AND DEBRIS. HYBRID DITCHES WILL SERVE
AS THE MAIN SOURCE OF POST-CONSTRUCTION STORMWATER QUALITY MEASURES. THE DITCHES WILL COLLECT
RUNOFF FROM THE ROADWAY AND FILTER THROUGH THE SOIL TO THE UNDER DRAINS AND ULTIMATELY THE INLETS.
SEDIMENT WILL BE FILTERED OUT THROUGH THE RETENTION MEDIA AND OTHER ELEMENTS WILL BE ABSORBED
NATURALLY THROUGH THE GRASS AND PLANTS.
C4 THE HYBRID DITCHES WILL BE CONSTRUCTED PER THE DETAILS ON SHEETS 8 AND 9. LOCATIONS FOR THE INLETS AND
DITCHES CAN BE FOUND IN THE PLANS ON SHEETS 2-7.
C5 MAINTENANCE OF THE DITCHES AND INLETS WILL REQUIRE REGULAR CLEANING OF DEBRIS FROM AROUND THE GRATES
TO ENSURE WATER CAN FLOW INTO THE STORMWATER SYSTEM. THE CITY OF CARAMEL WILL BE RESPONSIBLE FOR THE
MAINTENANCE IN ACCORDANCE WITH CHAPTER 8 OF THE IDEM STORMWATER QUALITY MANUAL.
