SWP SECTION
MOORESVILLE REGIONAL OFFICE
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for
Chemetall Foote Corp. New Office and Laboratory Project on May 5, 2011. Staff review of the plans and
specifications has determined that the project, as proposed, will comply with the Stormwater Regulations
set forth in Title 15A NCAC 2H.1000 and Session Law 2006-246. We are forwarding Permit No.
SW3110401, dated May 23, 2011, for the construction, operation and maintenance of the subject project
and the stormwater BMPs.
This permit shall be effective from the date of issuance until May 22, 2021, and shall be subject to the
conditions and limitations as specified therein. Please pay special attention to the Operation and
Maintenance requirements in this permit. Failure to establish an adequate system for inspection and
maintenance of the stormwater management system will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory'hearing upon written request within thirty (30) days following receipt of this permit.
This request must be in the form of a written petition, conforming to Chapter 150E of the North Carolina

additional information concerning this matter, please contact Brian Lowther at [phone]; or
[e-mail].

Bioretention Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
Iog in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important operation and maintenance procedures:
— Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
— Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
— Heavy equipment will NEVER be driven over the bioretention cell.
— Special care will be taken to prevent sediment from entering the bioretention cell.
— Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it once a month and within 24
hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

IV. PROJECT INFORMATION
1. in the space provided below, briefly summarize how the stormwater runoff will be treated.
The exisUng site has impervious cover. The new site has been designed so that the amount of new
im ervious area above the existing impervious cover is treated in 2 bioretention areas located on site. The
site actually treats a greater amount so that the untreated impervious areas is less than the existing
impervious
before this project (i.e. total_preimpervious area - 2.92 acres; total post impervious area - 4.13 acres need to
treat 4.1-2. 2 or 1.21 acres. We have treated 2.07 acres of iml2erviQus between 1he 2 bio-retention 12onds.
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUD Approval Date:
❑ Valid BWlding Permit Issued Date:
❑ Other: Date:
b.If claiming vested rights, identify the regulation(s) the project has been designed in accordance with:
❑ Coastal SW —1995 ❑ Ph 11 — Post Construction
3. Stormwater runoff from this project drains to the Broad River basin.
4. Total Property Area: 542 acres
5. Total Coastal Wetlands Area: acres
6. Total Surface Water Area: acres
7. Totai Property Area (4) — Total Coastal Wetlands Area (5) —Total Surface Water Area (6) = Total Project
Area+:542 acres
t Total project area shall be calculated to exclude the followin the normal pool of impounded structures, the area
between the banks of streams and rivers, the area below the Normal High Water (NHW) line or Mean Hugh Water
(MHW) line, and coastal wetlands landward from the NHW (or MHW) line. The resultant project area is used to
calculate overall percent built upon area (BUA). Nan -coastal wetlands landward of the NHW (or MHW) line may
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 7.6-12rol2. imp. area%
9. How many drainage areas does the project have? 2 (For high density, count 1 for each proposed engineered
stornwater BMP. For low density and other projects, use 1 for the whole property area)
10. Complete the following information for each drainage area identified in Project Information item 9. If there
are more than four drainage areas in the project, attach an additional sheet with the information for each area
provided in the same format as below.

Bioretention Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important operation and maintenance procedures:
— Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
— Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
— Heavy equipment will NEVER be driven over the bioretention cell.
— Special care will be taken to prevent sediment from entering the bioretention cell.
— Once a year, a soil test of the soil media will be conducted.
After die bioretention cell is established, I will inspect it once a month and within 24
hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
