Justification: A project that affects waters shall not be permitted unless the existing uses, and the
water quality to protect such uses, are protected. In determining that the proposed activity will
comply with state water quality standards (including designated uses, numeric criteria, narrative
criteria and the state's antidegradation policy), the Division must evaluate if the activity has avoided
and minimized impacts to waters, would cause or contribute to a violation of standards or would
result in secondary or cumulative impacts
3. Stormwater runoff from impervious surfaces shall be addressed by one or more of the regulated
programs: an approved Sediment and Erosion Control Plan, a NPDES stormwater permit, a NPDES
wastewater permit, a permit issued by the Division of Solid Waste. Any applicable approvals for
long term stormwater treatment shall be secured by the Permittee prior to conducting any impacts
approved in this modified Certification.
Citation: 15A NCAC 02H .0506(b); 15A NCAC 02H .0507(c)
Justification (applies to all listed conditions above): In order to protect against impairment of water
quality standards and best usage of receiving and downstream waters, water quality based
management practices must be employed to protect against direct or indirect discharge of waste or
other sources of water pollution. Surface water quality standards require that conditions of waters
be suitable for all best uses provided for in state rule (including, at minimum: aquatic life
propagation, survival, and maintenance of biological integrity, wildlife, secondary contact recreation,
agriculture) and that activities must not cause water pollution that precludes any best use on a
short-term or long-term basis. In determining that the proposed activity will comply with state water
quality standards (including designated uses, numeric criteria, narrative criteria and the state's
antidegradation policy), the Division must evaluate if the activity has avoided and minimized impacts
to waters, would cause or contribute to a violation of standards, or would result in secondary or
cumulative impacts
4. The permittee shall report to the DWR Asheville Regional Office any noncompliance with, and/or any
violation of, stream or wetland standards [15A NCAC 02B .0200], including but not limited to sediment
impacts to streams or wetlands. Information shall be provided orally within 24 hours (or the next
business day if a weekend or holiday) from the time the permittee became aware of the non-
compliance circumstances.
Citation: 15A NCAC 02H .0506(b); 15A NCAC 02H .0507(c)
Justification: Timely reporting of non-compliance is important in identifying and minimizing
detrimental impacts to water quality and avoiding impacts due to water pollution that precludes any
best use on a short-term or long-term basis.
5. No waste, spoil, solids, or fill of any kind shall occur in wetlands or waters beyond the footprint of
the approved impacts (including temporary impacts).

Justification: A project that affects waters shall not be permitted unless the existing uses, and the
water quality to protect such uses, are protected. Activities must not cause water pollution that
precludes any best use on a short-term or long-term basis. As cited in Stream Standards: (12) Oils,
deleterious substances, or colored or other wastes: only such amounts as shall not render the waters
injurious to public health, secondary recreation, or to aquatic life and wildlife, or adversely affect the
palatability offish, aesthetic quality, or impair the waters for any designated uses. As cited in
Wetland Standards: (c)(1) Liquids, fill or other solids, or dissolved gases shall not be present in
amounts that may cause adverse impacts on existing wetland uses, and (3) Materials producing
color or odor shall not be present in amounts that may cause adverse impacts on existing wetland
uses.
19. Heavy equipment working in wetlands shall be placed on mats or other measures shall be taken to
minimize soil disturbance and compaction.
Citation: 15A NCAC 02H .0506(b); 15A NCAC 02H .0507(c); 15A NCAC 028.0231
Justification: Wetland standards require maintenance or enhancement of existing uses of wetlands
such that hydrologic conditions necessary to support natural biological and physical characteristics
are protected, populations of wetland flora and fauna are maintained to protect biological integrity
of the wetland; and materials or substances are not present in amounts that may cause adverse
impact on existing wetland uses.
20. In accordance with 143-215.85(b), the permittee shall report any petroleum spill of 25 gallons or
more; any spill regardless of amount that causes a sheen on surface waters; any petroleum spill
regardless of amount occurring within 100 feet of surface waters; and any petroleum spill less than
25 gallons that cannot be cleaned up within 24 hours.

Justification: Person(s) owning or having control over oil or other substances upon notice of
discharge must immediately notify the Department, or any of its agents or employees, of the nature,
location, and time of the discharge and of the measures which are being taken or are proposed to be
taken to contain and remove the discharge. This action is required in order to contain or divert the
substances to prevent entry into the surface waters. Surface water quality standards require that
conditions of waters be suitable for all best uses provided for in state rule (including, at minimum:
aquatic life propagation, survival, and maintenance of biological integrity, wildlife, secondary
contact recreation; agriculture); and that activities must not cause water pollution that precludes
any best use on a short-term or long-term basis.
21. The permittee and their authorized agents shall conduct all activities in a manner consistent with
State water quality standards (including any requirements resulting from compliance with §303(d)
of the Clean Water Act), and any other appropriate requirements of State and Federal Law.
