Sue/Bryan — for your records, attached is an additional temporary culvert crossing detail that was taken from DEQ's
Erosion and Sediment Control Design Manual and included on our E&S drawing for this project. It differs slightly from
the culvert crossing detail that I provided in the PCN, but there is no difference in the already approved temporary
impact footprint, proposed limits of disturbance, restoration details or anything like that.
The project should start up in about a month or so, and Sue we have also included your notes on the E&SC
drawings. Thanks! j

Joey,
As we discussed, this has a requirement to notify me upon completion of the work at Stream 30.

REFER TO AUTHORIZED PERMITS FOR ADDITIONAL LOCAL, STATE, AND FEDERAL REQUIREMENTS.
STONE CROSSING AND CULVERT WILL BE INSTALLED SUCH THAT LOW FLOW PASSAGE OF WATER AND AQUATIC LIFE IS NOT INHIBITED.
MECHANICAL EQUIPMENT SHALL NOT OPERATE WITHIN STREAMS OR TRAVERSE STREAMS WITHOUT THE USE OF TEMPORARY CROSSING.
CONSTRUCT TEMPORARY STONE CROSSING AND COFFER DAM WITHIN CONSTRUCTION EASEMENT. CONSTRUCT DAMS USING SANDBAGS COVERED WITH CLEAN 20 MIL HDPE LINER. CONTRACTOR MAY USE OTHER
METHODS FOLLOWING APPROVAL FROM THE ENVIRONMENTAL INSPECTOR AND THE OWNER.
THE HEIGHT OF THE COFFER DAM SHALL BE CALCULATED BY USING H/4 + 1 -FEET WHERE H = HEIGHT OF STREAM BANK WITH A 2 -FEET MINIMUM DAM HEIGHT. ADDITIONAL HEIGHT MAY BE REQUIRED BASED ON
FLOW CONDITIONS AT THE TIME OF CONSTRUCTION. COFFER DAMS TO BE REMOVED UPON COMPLETION OF OPEN CUT PIPELINE INSTALLATION AND STREAM BED RESTORATION TO ALLOW NATURAL WATER FLOW.
CONTACTOR SHALL DEWATER AREA BETWEEN DAMS AND ENSURE TIGHT SEAL OF DAMS PRIOR TO TRENCHING. CONTRACTOR SHALL BE RESPONSIBLE FOR PASSING ALL WATER WHICH IS TO BE FILTERED THROUGH A
SILT BAG. INSTALL 12 -INCH COMPOST FILTER SOCK ON THREE DOWNGRADIENT SIDES OF SILT BAG. PUMPS SHALL BE PLACED WITHIN SECONDARY CONTAINMENT TO REDUCE POTENTIAL FOR FUEL SPILLS.
INSTALL FLUME PIPE AND PROVIDE A MINIMUM OF 12 -INCHES OF COVER OR 1/2 DIAMETER OF PIPE (WHICHEVER IS GREATER). CONTRACTOR IS RESPONSIBLE TO SIZE FLUME PIPE TO ADEQUATELY ACCOMMODATE
BANK FULL FLOWS. ALIGN FLUME PIPE(S) TO PREVENT BANK EROSION AND STREAMBED SCOUR.
ALL STREAM CROSSINGS SHOULD BE MADE PERPENDICULAR TO THE STREAM TO THE EXTENT PRACTICAL. INSTALL SILT FENCE PERPENDICULAR TO THE CONSTRUCTION EASEMENT AT STREAM CROSSINGS. EXTEND
SILT FENCE 20 -FEET MINIMUM ON BOTH SIDES OF EDGE OF CONSTRUCTION EASEMENT OR AS SHOWN ON PLANS.
LIMIT THE REMOVAL OF VEGETATION TO THE CONSTRUCTION EASEMENT AREA. ONLY HAND CLEARING IS ALLOWED ON STREAM BANKS AND WITHIN 10 -FEET OF TOP OF BANK.
STREAM CROSSINGS SHOULD BE CONDUCTED "IN THE DRY" DURING LOW FLOW CONDITIONS. LOCAL WEATHER CONDITIONS SHALL BE MONITORED IN ORDER TO AVOID ANTICIPATED RAINFALL EVENTS DURING, OR
IMMEDIATELY FOLLOWING, INSTALLATION OF THE PIPE.
CROSSINGS SHALL BE EXECUTED IN THE MINIMAL AMOUNT OF TIME NECESSARY; BEGIN INSTREAM WORK IN THE MORNING, INSTALLATION AND RESTORATION SHALL OCCUR WITHIN A 24-HOUR PERIOD TO THE
FULLEST EXTENT PRACTICAL. IN NO INSTANCE SHOULD INSTALLATION AND RESTORATION EXCEED 48 HOURS WITHOUT APPROVAL OF THE ENVIRONMENTAL MONITOR.
CONTRACTOR SHALL ATTEMPT TO SEGREGATE STREAM BED SUBSTRATE FROM SUBGRADE.
DO NOT REMOVE FLUME PIPE DURING TRENCHING, PIPELAYING, OR BACKFILLING ACTIVITIES, OR INITIAL STREAMBED RESTORATION EFFORTS.
NO WASTES, SPOILS, SOLIDS OR FILLS WILL BE PLACED WITHIN STREAMS, WETLANDS, OR RIPARIAN AREAS BEYOND THE LIMITS OF THOSE DEPICTED ON THE DRAWINGS.
ONCE CONSTRUCTION HAS BEEN COMPLETED STREAM CROSSINGS SHALL BE RESTORED TO ORIGINAL CONDITIONS TO FULLEST EXTENT PRACTICAL, INCLUDING SUBGRADE AND STREAM SUBSTRATE MATERIALS.
ADDITIONAL SITE SPECIFIC MEASURES MAY BE NECESSARY IN ORDER TO PROTECT AFFECTED STREAMS AND PREVENT VIOLATIONS OF WATER QUALITY STANDARDS.
ENVIRONMENTAL INSPECTOR TO ASSIST IN DETERMINATION OF WHETHER PUMP AROUND OR FLUME STREAM CROSSING METHOD IS TO BE USED.
