A.1. REMOVE/OPEN LID ON NYLOPLAST INLINE DRAIN
A.2. REMOVE AND CLEAN FLEXSTORM FILTER IF INSTALLED
A.3. USING A FLASHLIGHT AND STADIA ROD, MEASURE DEPTH OF SEDIMENT AND RECORD ON MAINTENANCE LOG
A.4. LOWER A CAMERA INTO ISOLATOR ROW FOR VISUAL INSPECTION OF SEDIMENT LEVELS (OPTIONAL)
A.5. IF SEDIMENT IS AT, OR ABOVE, 3" (80 mm) PROCEED TO STEP 2. IF NOT, PROCEED TO STEP 3.
B. ALL ISOLATOR ROWS
B.I. REMOVE COVER FROM STRUCTURE AT UPSTREAM END OF ISOLATOR ROW
B.2. USING A FLASHLIGHT, INSPECT DOWN THE ISOLATOR ROW THROUGH OUTLET PIPE
i) MIRRORS ON POLES OR CAMERAS MAY BE USED TO AVOID A CONFINED SPACE ENTRY
I!) FOLLOW OSHA REGULATIONS FOR CONFINED SPACE ENTRY IF ENTERING MANHOLE
B.3. IF SEDIMENT IS AT, OR ABOVE, 3" (80 mm) PROCEED TO STEP 2. IF NOT, PROCEED TO STEP 3.
STEP 2) CLEAN OUT ISOLATOR ROW USING THE JETVAC PROCESS
A. A FIXED CULVERT CLEANING NOZZLE WITH REAR FACING SPREAD OF 45" (1.1 m) OR MORE IS PREFERRED
B. APPLY MULTIPLE PASSES OF JETVAC UNTIL BACKFLUSH WATER IS CLEAN
C. VACUUM STRUCTURE SUMP AS REQUIRED
STEP 3) REPLACE ALL COVERS, GRATES, FILTERS, AND LIDS; RECORD OBSERVATIONS AND ACTIONS.
STEP 4) INSPECT AND CLEAN BASINS AND MANHOLES UPSTREAM OF THE STORMTECH SYSTEM.
NOTES

Other
Spills and Leaks
Oil, chemical or other hazardous substance spills and leaks that exceed the reportable threshold
will be reported to the DEQ in accordance with Part III G of the Permit as soon as the discharge is
discovered, and in no case later than within 24 hours. A reportable quantity of oil is defined by the
EPA as a discharge to surface waters that causes a sheen, discoloration, and/or an emulsion. A
written report of the unauthorized discharge shall be submitted to the DEQ and VSMP authority
within five days of the discovery of the discharge and include the information listed below:
• Name, address, and telephone number of the person reporting and the responsible party
• Specific location of the incident
• Date and time the incident occurred or was discovered
• Name of the chemical/material released
• Source and cause of the release
• Total quantity discharged
• Medium into which the substance was discharged
• Amount spilled into water
• Weather conditions
• Name of the carrier or vessel, the railcar/truck number, or other identifying
information
• Number and type of injuries or fatalities
• Whether an evacuation has occurred
• Estimation of the dollar amount of property damage
• Description of current and future cleanup actions
• Other agencies notified or about to be notified

Materials and equipment necessary for oil or chemical spill/ leak cleanup will be kept in the
temporary material storage trailer onsite. Equipment will include, but not be limited to, brooms,
dust pans, mops, rags, gloves, goggles, universal absorbents, sand, saw dust, and plastic and metal
trash containers.
All oil or other chemical spills/ leaks will be stopped, contained, and cleaned up immediately upon
discovery. Those large enough to reach the stone sewers will be reported to the National Response
Center at 1-800-424-8802. In the event of a hazardous spill contact: 9-1-1
Fuels and Oils
The State Code of Virginia §62.1-44.34:19, states that discharges that may be reasonably expected
to enter state waters, lands or storm drains must be reported. In the event of a spill, it will be
stopped, contained, and cleaned up immediately and the material, including any contaminated soil,
will be disposed of according to all federal, state, and local regulations.
Any on -site storage tanks will have a means of secondary containment.
All vehicles on site will be monitored for leaks and receive regular preventive maintenance to
reduce the chance of leakage.
Petroleum products will be stored in labeled, sealed containers.
Spill kits will be included with all fueling sources and maintenance activities
Hazardous and Toxic Chemicals
Spills of hazardous or toxic chemicals that exceed the reportable quantity threshold must be
reported, as previously stated. The EPA lists reportable quantity thresholds for each chemical
under 40 CFR Part 110, 40 CFR part 117, or 40 CFR part 302.
All paint containers and curing compounds will be tightly sealed and stored when not required for
use. Excess paint will not be discharged to the storm sewers but will be properly disposed
according to the manufacturer's instructions. Spray guns will be cleaned on a removable tarp.
Chemicals used on -site are kept in small quantities and stored in closed containers undercover and
kept out of direct contact with stormwater. As with fuels and oils, any inadvertent spills will be
cleaned up immediately and disposed of according to federal, state, and local regulations.
Fertilizers will be applied only in the minimum amounts recommended by the manufacturer.
Fertilizers will be worked into the soil to limit exposure to stormwater.
Fertilizers will be stored under cover and partially used bags will be transferred to a sealable bin to
avoid spills.
Sanitary Waste
Portable lavatories are located on -site and are serviced on a regular basis by a contractor. They will
be located in upland areas away from direct contact with surface waters. Any spills occurring
during servicing will be cleaned up immediately, including any contaminated soils, and disposed
of according to all federal, state, and local regulations.
Concrete
Concrete trucks will not be allowed to wash out or discharge surplus concrete or drum wash water
on the site, except in a specially designated concrete washout area which contains all wash water
resulting from washout activities.
Form release oil used for decorative stonework will be applied over a pallet covered with an
absorbent material to collect excess fluid. The absorbent material will be replaced and disposed of
properly when saturated.
Water Testing
When testing/cleaning of water supply lines, the discharge from the tested pipe will be collected
and conveyed to a completed stormwater pipe system for ultimate discharge into a sedimentation
basin or SWM/BMP facility.

DISCHARGE AUTHORIZATION AND SPECIAL CONDITIONS
A. Coverage under this general permit.
During the period beginning with the date of coverage under this general permit and lasting
until the general permit's expiration date, the operator is authorized to discharge stormwater
from construction activities.
This general permit also authorizes stormwater discharges from support activities (e.g.,
concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated
material disposal areas, borrow areas) located on -site or off -site provided that:
a. The support activity is directly related to the construction activity that is required to have
general permit coverage for discharges of stormwater from construction activities;
b. The support activity is not a commercial operation, nor does it serve multiple unrelated
construction activities by different operators;
c. The support activity does not operate beyond the completion of the last construction
activity it supports;
d. The support activity is identified in the registration statement at the time of general permit
coverage;
e. Appropriate control measures are identified in a stormwater pollution prevention plan and
implemented to address the discharges from the support activity areas; and
f. All applicable state, federal, and local approvals are obtained for the support activity.
B. Limitations on coverage.
1. Post -construction discharges. This general permit does not authorize stormwater discharges
that originate from the site after construction activities have been completed and the site,
including any support activity sites covered under the general permit registration, has
undergone final stabilization. Post -construction industrial stormwater discharges may need to
be covered by a separate VPDES permit.
Discharges mixed with nonstormwater. This general permit does not authorize discharges that
are mixed with sources of nonstormwater, other than those discharges that are identified in
Part I E (Authorized nonstormwater discharges) and are in compliance with this general
permit.

approved stormwater management plan is not required. In lieu of an approved stormwater
management plan, the SWPPP shall include a description of, and all necessary
calculations supporting, all post -construction stormwater management measures that will
be installed prior to the completion of the construction process to control pollutants in
stormwater discharges after construction operations have been completed. Structural
measures should be placed on upland soils to the degree possible. Such measures must
be designed and installed in accordance with applicable VESCP authority, VSMP
authority, state, and federal requirements, and any necessary permits must be obtained.
Pollution prevention plan. A pollution prevention plan that addresses potential pollutant -
generating activities that may reasonably be expected to affect the quality of stormwater
discharges from the construction activity, including any support activity. The pollution
prevention plan shall:
a. Identify the potential pollutant -generating activities and the pollutant that is expected to be

spill kits readily available);
(3) Prevent the discharge of soaps, solvents, detergents, and wash water from
construction materials, including the clean-up of stucco, paint, form release oils, and
curing compounds (e.g., providing (i) cover (e.g., plastic sheeting or temporary roofs)
to prevent contact with stormwater; (ii) collection and proper disposal in a manner to
prevent contact with stormwater; and (iii) a similarly effective means designed to
prevent discharge of these pollutants);
(4) Minimize the discharge of pollutants from vehicle and equipment washing, wheel wash
water, and other types of washing (e.g., locating activities away from surface waters
and stormwater inlets or conveyance and directing wash waters to sediment basins or
traps, using filtration devices such as filter bags or sand filters, or using similarly
effective controls);
(5) Direct concrete wash water into a leak -proof container or leak -proof settling basin. The
container or basin shall be designed so that no overflows can occur due to inadequate
sizing or precipitation. Hardened concrete wastes shall be removed and disposed of
in a manner consistent with the handling of other construction wastes. Liquid concrete
wastes shall be removed and disposed of in a manner consistent with the handling of
other construction wash waters and shall not be discharged to surface waters;
(6) Minimize the discharge of pollutants from storage, handling, and disposal of
construction products, materials, and wastes including (i) building products such as
asphalt sealants, copper flashing, roofing materials, adhesives, and concrete

wastes, waste concrete, and sanitary wastes;
(8) Address any other discharge from the potential pollutant -generating activities not
addressed above;
(9) Minimize the exposure of waste materials to precipitation by closing or covering waste
containers during precipitation events and at the end of the business day, or
implementing other similarly effective practices. Minimization of exposure is not
required in cases where the exposure to precipitation will not result in a discharge of
pollutants; and
f. Describe procedures for providing pollution prevention awareness of all applicable wastes,
including any wash water, disposal practices, and applicable disposal locations of such
wastes, to personnel in order to comply with the conditions of this general permit. The
operator shall implement the procedures described in the SWPPP.

1. Operators with day-to-day operational control over SWPPP implementation shall have a copy
of the SWPPP available at a central location on -site for use by those identified as having
responsibilities under the SWPPP whenever they are on the construction site.
Page 13 of 26
The operator shall make the SWPPP and all amendments, modifications, and updates
available upon request to the department, the VSMP authority, the EPA, the VESCP authority,
local government officials, or the operator of a municipal separate storm sewer system
receiving discharges from the construction activity. If an on -site location is unavailable to store
the SWPPP when no personnel are present, notice of the SWPPP's location shall be posted
near the main entrance of the construction site.
The operator shall make the SWPPP available for public review in an electronic format or in
hard copy. Information for public access to the SWPPP shall be posted and maintained in
accordance with Part II D. If not provided electronically, public access to the SWPPP may be
arranged upon request at a time and at a publicly accessible location convenient to the
operator or his designee but shall be no less than once per month and shall be during normal
business hours. Information not required to be contained within the SWPPP by this general
permit is not required to be released.
F. SWPPP implementation. The operator shall implement the SWPPP and subsequent
amendments, modifications, and updates from commencement of land disturbance until
termination of general permit coverage as specified in Part I F.
All control measures shall be properly maintained in effective operating condition in
accordance with good engineering practices and, where applicable, manufacturer
specifications. If a site inspection required by Part II G identifies a control measure that is not
operating effectively, corrective actions shall be completed as soon as practicable, but no later
than seven days after discovery or a longer period as established by the VSMP authority, to
maintain the continued effectiveness of the control measures.
If site inspections required by Part II G identify an existing control measure that needs to be
modified or if an additional or alternative control measure is necessary for any reason,
implementation shall be completed prior to the next anticipated measurable storm event. If
implementation prior to the next anticipated measurable storm event is impracticable, then
additional or alternative control measures shall be implemented as soon as practicable, but
no later than seven days after discovery or a longer period as established by the VSMP
authority.
G. SWPPP Inspections.
1. Personnel responsible for on -site and off -site inspections. Inspections required by this general
permit shall be conducted by the qualified personnel identified by the operator in the SWPPP.
The operator is responsible for ensuring that the qualified personnel conduct the inspection.
2. Inspection schedule.
a. For construction activities that discharge to a surface water identified in Part 11 B 5 and B
6 as impaired or having an approved TMDL or Part I B 7 as exceptional, the following
inspection schedule requirements apply:
(1) Inspections shall be conducted at a frequency of (i) at least once every four business
days or (ii) at least once every five business days and no later than 24 hours following
a measurable storm event. In the event that a measurable storm event occurs when
Page 14 of 26
there are more than 24 hours between business days, the inspection shall be
conducted on the next business day; and
(2) Representative inspections as authorized in Part II G 2 d shall not be allowed.
b. Except as specified in Part II G 2 a, inspections shall be conducted at a frequency of:
(1) At least once every five business days; or
(2) At least once every 10 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.
c. Where areas have been temporarily stabilized or land -disturbing activities will be
suspended due to continuous frozen ground conditions and stormwater discharges are
unlikely, the inspection frequency described in Part II G 2 a and 2 b may be reduced to
once per month. If weather conditions (such as above freezing temperatures or rain or
snow events) make discharges likely, the operator shall immediately resume the regular
inspection frequency.
d. Except as prohibited in Part II G 2 a (2), representative inspections may be utilized for
utility line installation, pipeline construction, or other similar linear construction activities
provided that:
(1) Temporary or permanent soil stabilization has been installed and vehicle access may
compromise the temporary or permanent soil stabilization and potentially cause
additional land disturbance increasing the potential for erosion;
(2) Inspections occur on the same frequency as other construction activities;
(3) Control measures are inspected along the construction site 0.25 miles above and
below each access point (i.e., where a roadway, undisturbed right-of-way, or other
similar feature intersects the construction activity and access does not compromise
temporary or permanent soil stabilization); and
(4) Inspection locations are provided in the inspection report required by Part II G.
e. If adverse weather causes the safety of the inspection personnel to be in jeopardy, the
inspection may be delayed until the next business day on which it is safe to perform the
inspection. Any time inspections are delayed due to adverse weather conditions, evidence
of the adverse weather conditions shall be included in the SWPPP with the dates of
occurrence.
3. Inspection requirements.
a. As part of the inspection, the qualified personnel shall:
(1) Record the date and time of the inspection and, when applicable, the date and rainfall
amount of the last measurable storm event;
Page 15 of 26
(2) Record the information and a description of any discharges occurring at the time of
the inspection or evidence of discharges occurring prior to the inspection;
(3) Record any land -disturbing activities that have occurred outside of the approved
erosion and sediment control plan;
(4) Inspect the following for installation in accordance with the approved erosion and
sediment control plan, identification of any maintenance needs, and evaluation of
effectiveness in minimizing sediment discharge, including whether the control has
been inappropriately or incorrectly used:
(a) All perimeter erosion and sediment controls, such as silt fence;
(b) Soil stockpiles, when applicable, and borrow areas for stabilization or sediment
trapping measures;
(c) Completed earthen structures, such as dams, dikes, ditches, and diversions for
stabilization and effective impoundment or flow control;
(d) Cut and fill slopes;

control sediment discharge from stormwater;
(f) Temporary or permanent channels, flumes, or other slope drain structures
installed to convey concentrated runoff down cut and fill slopes;
(g) Storm inlets that have been made operational to ensure that sediment laden
stormwater does not enter without first being filtered or similarly treated; and
(h) Construction vehicle access routes that intersect or access paved or public roads
for minimizing sediment tracking;
(5) Inspect areas that have reached final grade or that will remain dormant for more than
14 days to ensure:
(a) Initiation of stabilization activities have occurred immediately, as defined in
9VAC25-880-1; and
(b) Stabilization activities have been completed within seven days of reaching grade
or stopping work;
(6) Inspect for evidence that the approved erosion and sediment control plan, "agreement
in lieu of a plan," or erosion and sediment control plan prepared in accordance with

f. The locations where any evidence identified under Part II G 3 a (6) exists;
g. The locations where any additional control measure is needed;
h. A list of corrective actions required (including any changes to the SWPPP that are
necessary) as a result of the inspection or to maintain permit compliance;
i. Documentation of any corrective actions required from a previous inspection that have not
been implemented; and
The date and signature of the qualified personnel and the operator or its duly authorized
representative.
5. The inspection report shall be included into the SWPPP no later than four business days after
the inspection is complete.
The inspection report and any actions taken in accordance with Part II shall be retained by
the operator as part of the SWPPP for at least three years from the date that general permit
coverage expires or is terminated. The inspection report shall identify any incidents of
noncompliance. Where an inspection report does not identify any incidents of noncompliance,
the report shall contain a certification that the construction activity is in compliance with the
SWPPP and this general permit. The report shall be signed in accordance with Part III K of
this general permit.
H. Corrective actions.
The operator shall implement the corrective actions identified as a result of an inspection as
soon as practicable but no later than seven days after discovery or a longer period as
approved by the VSMP authority. If approval of a corrective action by a regulatory authority
(e.g., VSMP authority, VESCP authority, or the department) is necessary, additional control
measures shall be implemented to minimize pollutants in stormwater discharges until such
approvals can be obtained.
The operator may be required to remove accumulated sediment deposits located outside of
the construction activity covered by this general permit as soon as practicable in order to
minimize environmental impacts. The operator shall notify the VSMP authority and the
department as well as obtain all applicable federal, state, and local authorizations,
approvals, and permits prior to the removal of sediments accumulated in surface waters
including wetlands.

4. The length of time that the discharge continued;
5. The volume of the discharge;
6. If the discharge is continuing, how long it is expected to continue;
7. If the discharge is continuing, what the expected total volume of the discharge will be; and
Any steps planned or taken to reduce, eliminate and prevent a recurrence of the present
discharge or any future discharges not authorized by this general permit.
Discharges reportable to the department and the VSMP authority under the immediate reporting
requirements of other regulations are exempted from this requirement.
H. Reports of unusual or extraordinary discharges. If any unusual or extraordinary discharge
including a "bypass" or "upset," as defined in this general permit, should occur from a facility and
the discharge enters or could be expected to enter surface waters, the operator shall promptly
notify, in no case later than within 24 hours, the department and the VSMP authority by telephone
after the discovery of the discharge. This notification shall provide all available details of the
incident, including any adverse effects on aquatic life and the known number of fish killed. The
operator shall reduce the report to writing and shall submit it to the department and the VSMP
authority within five days of discovery of the discharge in accordance with Part III 12. Unusual
and extraordinary discharges include any discharge resulting from:
1. Unusual spillage of materials resulting directly or indirectly from processing operations;
2. Breakdown of processing or accessory equipment;
3. Failure or taking out of service of some or all of the facilities; and

emergencies, the Virginia Department of Emergency Management maintains a 24-hour telephone
service at 1-800-468-8892.
4. Where the operator becomes aware of a failure to submit any relevant facts, or submittal of
incorrect information in any report, including a registration statement, to the department or the
VSMP authority, the operator shall promptly submit such facts or correct information.
J. Notice of planned changes.
1. The operator shall give notice to the department and the VSMP authority as soon as possible
of any planned physical alterations or additions to the permitted facility or activity. Notice is
required only when:
a. The operator plans an alteration or addition to any building, structure, facility, or installation
that may meet one of the criteria for determining whether a facility is a new source in
9VAC25-870-420;
b. The operator plans an alteration or addition that would significantly change the nature or
increase the quantity of pollutants discharged. This notification applies to pollutants that
are not subject to effluent limitations in this general permit; or
2. The operator shall give advance notice to the department and VSMP authority of any planned
changes in the permitted facility or activity, which may result in noncompliance with state
permit requirements.
K. Signatory requirements.
1. Registration statement. All registration statements shall be signed as follows:
a. For a corporation: by a responsible corporate officer. For the purpose of this chapter, a
responsible corporate officer means: (i) a president, secretary, treasurer, or vice-president
of the corporation in charge of a principal business function, or any other person who
performs similar policy -making or decision -making functions for the corporation; or (ii) the
manager of one or more manufacturing, production, or operating facilities, provided the
Page 22 of 26
manager is authorized to make management decisions that govern the operation of the
regulated facility including having the explicit or implicit duty of making major capital
investment recommendations, and initiating and directing other comprehensive measures
to assure long-term compliance with environmental laws and regulations; the manager
can ensure that the necessary systems are established or actions taken to gather
complete and accurate information for state permit application requirements; and where
authority to sign documents has been assigned or delegated to the manager in
accordance with corporate procedures;
b. For a partnership or sole proprietorship: by a general partner or the proprietor,
respectively; or
c. For a municipality, state, federal, or other public agency: by either a principal executive
officer or ranking elected official. For purposes of this chapter, a principal executive officer
of a public agency includes (i) the chief executive officer of the agency or (ii) a senior
executive officer having responsibility for the overall operations of a principal geographic
unit of the agency.
2. Reports and other information. All reports required by this general permit, including SWPPPs,
and other information requested by the board or the department shall be signed by a person
described in Part III K 1 or by a duly authorized representative of that person. A person is a
duly authorized representative only if:
a. The authorization is made in writing by a person described in Part III K 1;
b. The authorization specifies either an individual or a position having responsibility for the
overall operation of the regulated facility or activity such as the position of plant manager,
operator of a well or a well field, superintendent, position of equivalent responsibility, or
an individual or position having overall responsibility for environmental matters for the
operator. (A duly authorized representative may thus be either a named individual or any
individual occupying a named position); and
c. The signed and dated written authorization is included in the SWPPP. A copy shall be
provided to the department and VSMP authority, if requested.
3. Changes to authorization. If an authorization under Part III K 2 is no longer accurate because
a different individual or position has responsibility for the overall operation of the construction
activity, a new authorization satisfying the requirements of Part III K 2 shall be submitted to
the VSMP authority as the administering entity for the board prior to or together with any
reports or information to be signed by an authorized representative.
4. Certification. Any person signing a document under Part III K 1 or 2 shall make the following
certification:
"I certify under penalty of law that I have read and understand this document and that this
document and all attachments were prepared in accordance with a system designed to assure
that qualified personnel properly gathered and evaluated the information submitted. Based on
my inquiry of the person or persons who manage the system, or those persons directly
responsible for gathering the information, the information submitted is, to the best of my
knowledge and belief, true, accurate, and complete. I am aware that there are significant
Page 23 of 26
penalties for submitting false information, including the possibility of fine and imprisonment for
knowing violations."
L. Duty to comply. The operator shall comply with all conditions of this general permit. Any state
permit noncompliance constitutes a violation of the Virginia Stormwater Management Act and the
Clean Water Act, except that noncompliance with certain provisions of this general permit may
constitute a violation of the Virginia Stormwater Management Act but not the Clean Water Act.
Permit noncompliance is grounds for enforcement action; for state permit coverage, termination,
revocation and reissuance, or modification; or denial of a state permit renewal application.
The operator shall comply with effluent standards or prohibitions established under § 307(a)
of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish
these standards or prohibitions or standards for sewage sludge use or disposal, even if this
general permit has not yet been modified to incorporate the requirement.
M. Duty to reapply. If the operator wishes to continue an activity regulated by this general permit
after the expiration date of this general permit, the operator shall submit a new registration
statement at least 60 days before the expiration date of the existing general permit, unless
permission for a later date has been granted by the board. The board shall not grant permission
for registration statements to be submitted later than the expiration date of the existing general
permit.
N. Effect of a state permit. This general permit does not convey any property rights in either real
or personal property or any exclusive privileges, nor does it authorize any injury to private property
or invasion of personal rights, or any infringement of federal, state or local law or regulations.
O. State law. Nothing in this general permit shall be construed to preclude the institution of any
legal action under, or relieve the operator from any responsibilities, liabilities, or penalties
established pursuant to any other state law or regulation or under authority preserved by § 510 of
the Clean Water Act. Except as provided in general permit conditions on "bypassing" (Part III U)
and "upset' (Part III V), nothing in this general permit shall be construed to relieve the operator
from civil and criminal penalties for noncompliance.
P. Oil and hazardous substance liability. Nothing in this general permit shall be construed to
preclude the institution of any legal action or relieve the operator from any responsibilities,
liabilities, or penalties to which the operator is or may be subject under §§ 62.1-44.34:14 through
62.1-44.34:23 of the State Water Control Law or § 311 of the Clean Water Act.
Q. Proper operation and maintenance. The operator shall at all times properly operate and
maintain all facilities and systems of treatment and control (and related appurtenances), which
are installed or used by the operator to achieve compliance with the conditions of this general
permit. Proper operation and maintenance also includes effective plant performance, adequate
funding, adequate staffing, and adequate laboratory and process controls, including appropriate
quality assurance procedures. This provision requires the operation of back-up or auxiliary
facilities or similar systems, which are installed by the operator only when the operation is
necessary to achieve compliance with the conditions of this general permit.
R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of
treatment or management of pollutants shall be disposed of in a manner so as to prevent any
pollutant from such materials from entering surface waters and in compliance with all applicable
state and federal laws and regulations.
Page 24 of 26
S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in
violation of this general permit that has a reasonable likelihood of adversely affecting human
health or the environment.
T. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in an
enforcement action that it would have been necessary to halt or reduce the permitted activity in
order to maintain compliance with the conditions of this general permit.
U. Bypass.
1. 'Bypass," as defined in 9VAC25-870-10, means the intentional diversion of waste streams
from any portion of a treatment facility. The operator may allow any bypass to occur that does
not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to
ensure efficient operation. These bypasses are not subject to the provisions of Part III U 2 and
3.
2. Notice.
a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the
operator shall submit prior notice to the department, if possible at least 10 days before the
date of the bypass.
b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as
required in Part III I.
3. Prohibition of bypass.
a. Except as provided in Part III U 1, bypass is prohibited, and the board or department may
take enforcement action against an operator for bypass unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property
damage. Severe property damage means substantial physical damage to property,
damage to the treatment facilities that causes them to become inoperable, or
substantial and permanent loss of natural resources that can reasonably be expected
to occur in the absence of a bypass. Severe property damage does not mean
economic loss caused by delays in production;
(2) There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes, or maintenance during normal
periods of equipment downtime. This condition is not satisfied if adequate back-up
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass that occurred during normal periods of equipment
downtime or preventive maintenance; and
(3) The operator submitted notices as required under Part III U 2.
b. The department may approve an anticipated bypass, after considering its adverse effects,
if the department determines that it will meet the three conditions listed in Part III U 3 a.
Page 25 of 26
V. Upset.
1. An "upset," as defined in 9VAC25-870-10, means an exceptional incident in which there is
unintentional and temporary noncompliance with technology -based state permit effluent
limitations because of factors beyond the reasonable control of the operator. An upset does
not include noncompliance to the extent caused by operational error, improperly designed
treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or
careless or improper operation.
2. An upset constitutes an affirmative defense to an action brought for noncompliance with
technology -based state permit effluent limitations if the requirements of Part III V 4 are met.
A determination made during administrative review of claims that noncompliance was caused
by upset, and before an action for noncompliance, is not a final administrative action subject
to judicial review.
3. An upset does not include noncompliance to the extent caused by operational error,
improperly designed treatment facilities, inadequate treatment facilities, lack of preventative
maintenance, or careless or improper operation.
4. An operator who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs or other relevant evidence that:
a. An upset occurred and that the operator can identify the cause of the upset;
b. The permitted facility was at the time being properly operated;
c. The operator submitted notice of the upset as required in Part III I; and
d. The operator complied with any remedial measures required under Part III S.
5. In any enforcement proceeding, the operator seeking to establish the occurrence of an upset
has the burden of proof.
W. Inspection and entry. The operator shall allow the department as the board's designee, the
VSMP authority, EPA, or an authorized representative of either entity (including an authorized
contractor), upon presentation of credentials and other documents as may be required by law to:
1. Enter upon the operator's premises where a regulated facility or activity is located or
conducted, or where records shall be kept under the conditions of this general permit;
2. Have access to and copy, at reasonable times, any records that shall be kept under the
conditions of this general permit;
3. Inspect and photograph at reasonable times any facilities, equipment (including monitoring
and control equipment), practices, or operations regulated or required under this general
permit; and
4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance
or as otherwise authorized by the Clean Water Act or the Virginia Stormwater Management
Act, any substances or parameters at any location.
Page 26 of 26
For purposes of this section, the time for inspection shall be deemed reasonable during regular
business hours, and whenever the facility is discharging. Nothing contained herein shall make an
inspection unreasonable during an emergency.
X. State permit actions. State permit coverage may be modified, revoked and reissued, or
terminated for cause. The filing of a request by the operator for a state permit modification,
revocation and reissuance, or termination, or a notification of planned changes or anticipated
noncompliance does not stay any state permit condition.
Y. Transfer of state permit coverage.
1. State permits are not transferable to any person except after notice to the department. Except
as provided in Part III Y 2, a state permit may be transferred by the operator to a new operator
only if the state permit has been modified or revoked and reissued, or a minor modification
made, to identify the new operator and incorporate such other requirements as may be
necessary under the Virginia Stormwater Management Act and the Clean Water Act.
As an alternative to transfers under Part III Y 1, this state permit may be automatically
transferred to a new operator if:
a. The current operator notifies the department at least 30 days in advance of the proposed
transfer of the title to the facility or property;
b. The notice includes a written agreement between the existing and new operators
containing a specific date for transfer of state permit responsibility, coverage, and liability
