Subject: Permit Renewal
State Stormwater Management Permit No. SW3110401
Albemarle U.S. New Office and Laboratory Project
Cleveland County
Dear Mr. Bruce:
Effective August 1, 2013 the State Stormwater program has been transferred from the Division of Water
Quality (DWQ) to the Division of Energy, Mineral and Land Resources (DEMLR). All previous references
to DWQ will remain in older stormwater permits issued prior to August 1, 2013 until they are modified.
Please note that this permit will now reference DEMLR as the Division responsible for issuance of the
permit.
The Central DEQ Office received a complete 8 year Stormwater Management Permit Renewal
Application for Albermarle U.S. New Office and Laboratory Project on January 11, 2021. The Division is
hereby notifying you that permit SW3110401 has been renewed on April 19, 2021 and shall be effective
until April 19, 2029. For your records, please find enclosed a renewed, updated, and re -issued permit
and a copy of the renewal application. Please keep this permit on file at all times. Please note that the
renewed, updated, and re -issued permit does not impose new or different terms; it merely restates
some of the previous terms to provide you with a better understanding of your obligations under the
permit.
The renewal and reissuance of this stormwater permit does not imply that the site is currently in
compliance with the terms and conditions of this state stormwater permit. The plans originally
approved on May 23, 2011 will remain in full force and effect in accordance with the regulations set
forth in Title 15A NCAC 21-1.1000 effective September 1,1995.
This permit is subject to the conditions and limitations as specified therein. Please pay special attention
to the conditions listed in this permit regarding the Operation and Maintenance of the BMP(s),
recordation of deed restrictions, procedures for changes of ownership, transferring the permit, and
renewing the permit. Failure to establish an adequate system for operation and maintenance of the
stormwater management system, to record deed restrictions, to transfer the permit, or to renew the
permit, 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 by filing a written petition with the Office of Administrative Hearings
(OAH). The written petition must conform to Chapter 150B of the North Carolina General Statutes and
must be filed with the OAH within thirty (30) days of receipt of this permit. You should contact the OAH
with all questions regarding the filing fee (if a filing fee is required) and/or the details of the filing
process at 6714 Mail Service Center, Raleigh, NC 27699-6714, or via telephone at 919-431-3000, or visit
their website at www.NCOAH.com. Unless such demands are made this permit shall be final and binding.
