General Permit Number VAR10RS83
WP0202200030
S.L. Williamson Asphalt Plat at Red Hill Quarry
Industrial
Albemarle
Dear Permittee:
DEQ has reviewed your permit modification request received complete on September 23, 2022 and determined
that the proposed 3.13 acre land -disturbing activity is covered under the General VPDES Permit for Discharges of
Stormwater from Construction Activities (VAR10). The effective date of this permit coverage modification is the
date of this letter. Please include a copy of this letter in the Stormwater Pollution Prevention Plan (SWPPP). You
may obtain a copy of the general permit from
hftps://Iaw.l i s.vi rg i nia.g ov/ad mi ncodettitleg/aaen cy25/chapter880/secti o n70/.
The general permit contains the conditions of coverage and Stormwater Pollution Prevention Plan (SWPPP)
requirements. Please print the general permit and read it carefully as you will be responsible for compliance with
all permit conditions. Coverage under this construction general permit does not relieve the operator of complying
with all other federal, state, or local laws and regulations.
Our records indicate that your site may discharge to waters identified as impaired or exceptional. Please see below
for additional requirements:
1. Does this proposed land -disturbing activity discharge to a surface water identified as impaired or for which a
TMDL wasteload allocation has been established and approved prior to the term of the general permit for (i)
sediment or a sediment -related parameter or (ii) nutrients? Yes. If YES, then the following general permit (Part
I B 4 a) and SWPPP requirements (Part II B 5) must be implemented for the land -disturbing activity:
• Permanent or temporary soil stabilization shall be applied to denuded areas within seven (7) days after final
grade is reached on any portion of the site;
• Nutrients (e.g., fertilizers) shall be applied in accordance with manufacturer's recommendations or an
approved nutrient management plan and shall not be applied during rainfall events;
• Inspections shall be conducted at a frequency of (i) at least once every four (4) business days or (ii) at least
once every (5) business days and no later than 24 hours following a measurable storm event. In the event
that a measurable storm event occurs when there are more than 24 hours between business days, the
inspection shall be conducted on the next business day; and
Representative inspections used by utility line installation, pipeline construction, or other similar linear
construction activities shall inspect all outfalls.
Does this proposed land -disturbing activity discharge to a surface water identified as impaired or for which a
TMDL wasteload allocation has been established and approved prior to the term of the general permit for
polychlorinated biphenyl (PCB)? No. If YES, then the following general permit (Part I B 4 b) and SWPPP
requirements (Part 11 B 6) must be implemented for the land -disturbing activity if the construction activity
involves the demolition of structures (i) equal to or greater than 10,000 square feet and (ii) built or renovated
on or before January 1, 1980:
• Implement an approved erosion and sediment control plan;
• Dispose of PCB -contaminated materials in compliance with applicable state, federal, and local requirements
to minimize the exposure of PCB -containing building materials;
• Inspections shall be conducted at a frequency of (i) at least once every four (4) business days or (ii) at least
once every (5) business days and no later than 24 hours following a measurable storm event. In the event
that a measurable storm event occurs when there are more than 24 hours between business days, the
inspection shall be conducted on the next business day; and
• Representative inspections used by utility line installation, pipeline construction, or other similar linear
construction activities shall inspect all outfalls.
3. Does this proposed land -disturbing activity discharge to an exceptional water as identified in Section 30 of the
Water Quality Standards, 9VAC 25-260? No. If YES, then the following general permit (Part I B 5) and SWPPP
requirements (Part II B 7) must be implemented for the land -disturbing activity:
• Permanent or temporary soil stabilization shall be applied to denuded areas within seven (7) days after final
grade is reached on any portion of the site;
• Nutrients (e.g., fertilizers) shall be applied in accordance with manufacturer's recommendations or an
approved nutrient management plan and shall not be applied during rainfall events;
• Inspections shall be conducted at a frequency of (i) at least once every four (4) business days or (ii) at least
once every (5) business days and no later than 24 hours following a measurable storm event. In the event
that a measurable storm event occurs when there are more than 24 hours between business days, the
inspection shall be conducted on the next business day; and
• Representative inspections used by utility line installation, pipeline construction, or other similar linear
construction activities shall inspect all outfalls.
The general permit requires that you submit a complete Notice of Termination packet no later than 30 days after
meeting one or more of the termination conditions set forth in the general permit (Part I F). In accordance with the
Virginia Stormwater Management Program State Permit Fee Regulation (9VAC 25-870-830), you may be required
to pay an annual permit maintenance fee until coverage under this general permit has been terminated. If you are
required to pay an annual permit maintenance fee, you will receive an invoice from the VSMP Authority.
The general permit will expire on June 30, 2024. The conditions of the general permit require that you submit a new
registration statement at least 60 days prior to that date if you wish to continue coverage under the general permit,
unless permission for a later date has been granted by the Board. Permission cannot be granted to submit the
registration statement after the expiration date of the general permit.
If you have any questions about this permit, please contact the DEQ Office of Stormwater Management at

Sincerely,
