RULES DETAILING THE DOCUMENTATION OF THESE INSPECTIONS BECAME EFFECTIVE OCTOBER 1, 2010. TO SIMPLIFY DOCUMENTATION OF SELF -INSPECTION REPORTS AND NPDES SELF -MONITORING REPORTS, A COMBINED FORM IS NOW AVAILABLE. THE NEW FORM WAS DEVELOPED TO SATISFY THE REQUIREMENTS OF THE SEDIMENTATION POLLUTION CONTROL ACT AND THE NPDES STORM WATER PERMIT FOR AGENCY REVIEW ACTIVITIES, NCG 010000. BEGINNING AUGUST 1, 2013, THE DIVISION OF ENERGY, MINERAL, AND LAND RESOURCES IS RESPONSIBLE FOR ADMINISTERING BOTH THE SPCAAND THE NPDES STORM WATER PERMIT FOR AGENCY REVIEW ACTIVITIES, NCG 010000. THE COMBINED FORM SHOULD MAKE IT EASIER TO COMPLY WITH SELF -INSPECTION REQUIREMENTS.

IF NATIVE VEGETATION IS USED INSTEAD OF TURF, VEGETATION HAS TO BE MOWED ONLY SEASONALLY TO RETARD THE GROWTH OF WOODY VEGETATION. ROUTINE MOWING IS REQUIRED IF TURF GRASSES ARE USED. THE RECOMMENDATION IS THAT GRASS BE CUT NO LOWER THAN 2 INCHES. IN ADDITION, THE GRASS SHOULD BE ALLOWED TO GROW TO THE MAXIMUM HEIGHT CONSISTENT WITH THE SPECIES AND AESTHETIC REQUIREMENTS. SWALES POPULATED WITH WETLAND VEGETATION OR OTHER LOW -MAINTENANCE GROUND COVER DO NOT REQUIRE MOWING OF THE CHANNEL. THE FREQUENCY OF TRASH REMOVAL DEPENDS ON THE LOCATION AND ATTRACTIVENESS OF THE SWALE AS A DISPOSAL SITE. EXCESSIVE SEDIMENT SHOULD NOT ACCUMULATE IF EROSION IS CONTROLLED ADEQUATELY UPSTREAM. HOWEVER, IF EXCESSIVE SILTATION OCCURS, THE SEDIMENT MUST BE REMOVED PERIODICALLY (NO LESS THAN ONCE ANNUALLY). SEDIMENT THAT ACCUMULATES IN THE SWALE MAY BE PRONE TO RESUSPENSION DURING LARGE STORM EVENTS AND CAN KILL THE GRASS. SEDIMENT SHOULD BE REMOVED WHEN IT REACHES A DEPTH OF 1 INCHES OR WHEN IT COVERS THE GRASS. ADDITIONAL ANNUAL MAINTENANCE ACTIVITIES ARE AS FOLLOWS: REPAIR EROSION AND REGRADE THE SWALE TO ENSURE THAT RUNOFF FLOWS EVENLY IN A THIN SHEET THROUGH THE SWALE.

Soil tests may be conducted by the State soil testing lab or a reputable commercial laboratory. Information on free soil testing is available from the Agronomic Division of the North Carolina Department of Agriculture or the Agricultural Extension Service. Where sodding must be planned without soil tests the following soil amendments may be sufficient: • Pulverized agricultural limestone at a rate of 2 tons/acre (100 Ib/1,000 ft2) • Fertilizer at a rate of 1,000 lb/acre (25 Ib/1,000 ft2) of 10-10-10 in fall or 5-10-10 in spring. Equivalent nutrients may be applied with other fertilizer formulations. These amendments should be spread evenly over the area, and incorporated into the top 4-8 inches of soil by disking, harrowing, or other effective means. Prior to laying sod, clear the soil surface of trash, debris, roots, branches, stones, and clods larger than 2 inches in diameter. Fill or level low spots in order to avoid standing water. Rake or harrow the site to achieve a smooth and level final grade.Complete soil preparation by rolling or cultipacking to firm the soil. Avoid using heavy equipment on the area, particularly when the soil is wet, as this may cause excessive compaction, and make it difficult for the sod to take root. Sod installation 1. Moistening the sod after it is unrolled helps maintain its viability. Store it in the shade during installation. 2. Rake the soil surface to break the crust just before laying sod. During the summer, lightly irrigate the soil, immediately before laying the sod to cool the soil, reduce root burning, and dieback. 3. Do not sod on gravel, frozen soils, or soils that have been treated recently with sterilants or herbicides. 4. Lay the first row of sod in a straight line with subsequent rows placed paralled to and butting tightly against each other. Stagger strips in a brick -like pattern. Be sure that the sod is not streached or overlapped and that all joints are butted tightly to prevent voids. Use a knife or sharp spade to trim and fit irregularly shaped areas. 5. Install strips of sod with their longest dimension perpendicular to the slope. On slopes 3:1 or greater, or wherever erosion may be a problem, secure sod with pegs or staples. 6. As sodding of clearly defined areas is completed, roll sod to provide firm contact between roots and soil. 7. After rolling, irrigate until the soil is wet 4 inches below the sod. 8. Keep sodded areas moist to a depth of 4 inches until the grass takes root. This can be determined by gently tugging on the sod —resistance indicates that rooting has occurred. 9. Mowing should not be attempted until the sod is firmly rooted, usually 2-3 weeks. MAINTENANCE AFTER the first week, water as necessary to maintain adequate moisture in the root zone and prevent dormancy of the sod.Do not remove more than one-third of the shoot in any mowing. Grass height should be maintained between 2 and 3 inches unless otherwise specified. After the first growing season, established sod requires fertilization, and may also require lime.

PH: 500-722-2040 Poseyville, IN 47633 www.nagreen.com A B C NOTES: *Horizontal staple spacing should be altered if necessary to allow staples to secure the critical points along the channel surface. **In loose soil conditions, the use of staple or stake lengths greater than 6"(15cm) may be necessary to properly secure the RECP's. Disclaimer: The information presented herein is general design information only. For specific applications, consult an independent professional for further design guidance. Drawn on: 5-4-17 CHANNEL INSTALLATION DETAIL 1. Prepare soil before installing rolled erosion control products (RECPs), including any necessary application of lime, fertilizer, and seed. 2. Begin at the top of the channel by anchoring the RECPs in a 6"(15cm) deep X 6"(15cm) wide trench with approximately 12"(30cm) of RECPs extended beyond the up -slope portion of the trench. Use ShoreMax mat at the channel/culvert outlet as supplemental scour protection as needed. Anchor the RECPs with a row of staples/stakes approximately 12"(30cm) apart in the bottom of the trench. Backfill and compact the trench after stapling. Apply seed to the compacted soil and fold the remaining 12"(30cm) portion of RECPs back over the seed and compacted soil. Secure RECPs over compacted soil with a row of staples/stakes spaced approximately 12" apart across the width of the RECPs. 3. Roll center RECPs in direction of water flow in bottom of channel. RECPs will unroll with appropriate side against the soil surface. All RECPs must be securely fastened to soil surface by placing staples/stakes in appropriate locations as shown in the staple pattern guide. 4. Place consecutive RECPs end -over -end (Shingle style) with a 4"-6" overlap. Use a double row of staples staggered 4" apart and 4" on center to secure RECPs. 5. Full length edge of RECPs at top of side slopes must be anchored with a row of staples/stakes approximately 12"(30cm) apart in a 6"(15cm) deep X 6"(15cm) wide trench. Backfill and compact the trench after stapling. 6. Adjacent RECPs must be overlapped approximately 2"-5" (5-12.5cm) (Depending on RECPs type) and stapled. 7. In high flow channel applications a staple check slot is recommended at 30 to 40 foot (9 -12m) intervals. Use a double row of staples staggered 4"(10cm) apart and 4"(10cm) on center over entire width of the channel. 8. The terminal end of the RECPs must be anchored with a row of staples/stakes approximately 12" (30cm) apart in a 6"(15cm) deep X 6"(15cm) wide trench. Backfill and compact the trench after stapling.
