Dear Permittee:
Dee Freeman
Secretary
Subject: NPDES Stormwater New Permit—
Transition to General Permit NCG210000
Bonsal Chip Mill
COC Number NCG210409
Wake County
In response to your renewal application for continued coverage under stormwater General Permit NCG220000, the
Division of Water Quality (DWQ) is forwarding herewith a new Certificate of Coverage (COC) under the recently modified
stormwater General Permit NCG210000 for Timber Products. Stormwater discharges from Wood Chip Mills are now
eligible for coverage under General Permit NCG210000. The modified general permit was reissued on March 25, 2011
(effective April 1, 2011).
Rather than renew your coverage under General Permit NCG220000, which expired in 2008, the Division has transitioned
your facility under General Permit NCG210000 and issued you a new permit (with a different COC number). The Division
does not intend to renew General Permit NCG220000. This action was noticed publically from February 15 through March
18, 2011; the proposed modification to general permit NCG210000 was available on our website on February 8, 2011.
This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between the state of North Carolina and the U.S. Environmental Protection Agency, dated October 15, 2007
(or as subsequently amended.)
The following information is included with your permit package:
• A new Certificate of Coverage
• A copy of stormwater General Permit NCG210000
• A copy of a revised Technical Bulletin for this General Permit
• Two copies of the Stormwater Discharge Monitoring Report (SDMR) Form
• Two copies of the Qualitative Monitoring Report (QMR) Form
The General Permit authorizes discharges of stormwater associated with industrial activities at your facility, and it specifies
your obligations with respect to discharge controls, management, monitoring, and record keeping. Please review the new
permit to familiarize yourself with all the requirements.

Some significant differences in this General Permit from the old NCG220000 that your facility was covered under are:
➢ Stormwater Discharge Monitoring:
• Analytical monitoring is required if the facility retains exposed piles of sawdust, wood chips, bark, mulch, or other
similar material on site for more than seven (7) days.
• Monitoring frequency is twice a year (instead of annually).
• Monitoring parameters include pH (new), Chemical Oxygen Demand (COD) instead of BOD, and TSS (same).
• Vehicle maintenance activities trigger stormwater monitoring requirements for pH, Oil & Grease (0&G), and TSS.
• Tiered response requirements apply when samples exceed benchmark concentrations. Benchmarks are not limits.
• Monitoring results must be reported to DWQ within 30 days of lab report receipt (instead of annually).
• Qualitative Monitoring must be performed twice a year (instead of monthly).
You have entered this permit in "Year 3 — Period 2" of the sampling schedule, which ends June 30th. However, because of
the delayed mail -out of permit packages, your facility is expected to comply with sampling requirements beginning no
later than "Year 4 — Period 1." That means your facility must sample a representative storm event between July 1 and
December 31, 2011 (or, if applicable, reporting "No Flow" from a representative storm event on the SDMR Form within 30
days of that deadline, as outlined in Part III, Section E.)
➢ Stormwater Pollution Prevention Plan (SPPP):
• SPPP requirements reflect the current standard for most stormwater general permits and are more detailed than
the NCG220000 permit. Please review all the items thoroughly to update your current SPPP to be compliant with
this permit. For example, the site location map must identify any receiving waters that are impaired, and training
records must include signatures of employees trained annually.
• If a facility opts out of monitoring on the basis of removing accumulated material in a week or less, a log of when
material is generated and removed, as well as other details about removal, must be kept with the SPPP.
• Because of the transition to a new permit, the compliance schedule in Part III, Section A does not address your
facility's situation. However, many items in the SPPP are similar to those under the old NCG220000. Therefore, the
Division expects your operation to have its SPPP revised and implemented to comply with this permit within six
months of receipt of this permit package.
Your coverage under the General Permit is transferable only through the specific action of DWQ. This permit does not
affect the legal requirements to obtain other permits which may be required by DENR, nor does it relieve the permittee
from responsibility for compliance with any other applicable federal, state, or local law, rule, standard, ordinance, order,
judgment, or decree.
If you have any questions regarding this permit package please contact Bethany Georgoulias at [phone] with the
Stormwater Permitting Unit.
Sincerely,
forColeen H. Sullins
