Permit No. NCS000588
PART II MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and with the co-permittees shall implement a Stormwater Pollution
Prevention Plan (SPPP).
1. The SPPP must include Best Management Practices (BMPs), economically reasonable and
appropriate in light of current industry practices, that are selected, designed, installed,
implemented and maintained in accordance with good engineering practices to eliminate or
reduce pollutants in the permittee's discharge. The SPPP must identify all potential sources
of pollution that may reasonably be expected to affect the quality of stormwater discharges;
describe and ensure implementation of practices used to eliminate or reduce pollutants in
stormwater discharges; and ensure compliance with the terms and conditions of this
permit.
The SPPP shall include, at a minimum, the following items:
a. The SPPP shall include a list identifying each area where industrial materials or
activities are exposed to stormwater. Industrial materials or activities include, but
are not limited to: material handling equipment or activities; industrial machinery;
raw materials; industrial production and processes; intermediate products, by-
products, final products and waste products. Material handling activities include,
but are not limited to: the storage, loading and unloading, transportation, disposal,
or conveyance of raw material, intermediate products, final products and waste
products.
b. The SPPP shall include a list of the name(s) of all surface waters that receive
discharges from the permittee's site. The permittee must provide the size and
description of wetlands or other special aquatic sites that may receive discharges
from the airport. If there are discharges through any publicly owned or operated
storm sewer system, the SPPP must identify the publicly owned or operated storm
sewer system.
C. The SPPP shall include the identity of any receiving water into which the permittee
discharges.
d. The SPPP shall include a list and locations where reportable spills or leaks of
pollutants that have occurred at the facility during the three previous years.
e. The SPPP shall include the location(s) and/or descriptions where potential spills
and leaks could occur that could contribute pollutants to stormwater discharges,
and the corresponding outfall(s).
For each area where industrial materials or activities are exposed to stormwater,
the SPPP shall include a narrative description of storage practices, loading and
unloading activities, outdoor process areas, dust or particulate generating or
control processes, and waste disposal practices. The SPPP shall include a narrative
description of the potential pollutants which could be expected to be present in the
stormwater discharge from each outfall.
Page 4 of 45

Permit No. NCS000589
g. The SPPP shall describe and assess the potential for the following activities and
facility areas to contribute pollutants to stormwater discharges: aircraft, runway,
ground vehicle and equipment maintenance and cleaning; aircraft and runway
deicing operations (including apron and centralized aircraft deicing stations,
runways, taxiways and ramps). Commercial tenants or other fixed based operations
that conduct any of the operations listed in the previous sentence shall be
considered co-permittees under this permit regardless of whether or not they are
listed in Section C of Part I and must provide all of the above information to the
Airport Authority for inclusion in the Airport Authority's SPPP. If deicing chemicals
are used, the permittee must maintain a record of the types (including the Safety
Data Sheets [SDS]) used and the monthly quantities of deicing material only, not the
deicing and water mixtures, either as measured or estimated. This includes all
deicing chemicals, not just glycols and urea (e.g., potassium acetate), because large
quantities of these other chemicals can still have an adverse impact on receiving
waters. The pollutant list must include all significant materials, including any
hazardous substances or oil handled, treated, stored, or disposed of that have been
exposed to stormwater in the 3 years prior to the date the SPPP was prepared or
amended.
h. Site Plan. The permittee shall prepare and maintain as a part of the SPPP, a site plan
(the Site Plan), which shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination
of stormwater discharges. The Site Plan shall contain the following:
(i) The size of the property in acres.
(ii) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation
routes and surface waters within 1 mile of the site, the name of the receiving
water(s) to which the stormwater outfall(s) discharges, or if the discharge is
to a municipal separate storm sewer system, the name of the municipality
and the ultimate receiving waters, and accurate latitude and longitude of the
point(s) of discharge.
(iii) A site map drawn to scale (including a distance legend) showing: the site
property boundary, on -site and adjacent surface waters and known
wetlands, industrial activity areas (including storage of materials, disposal
areas, process areas, loading and unloading areas, storage tanks, fueling
stations, vehicle and equipment maintenance and/or cleaning areas,
machinery, access roads and tracks, transfer areas for substances in bulk,
locations used for the treatment, storage or disposal of wastes), locations of
all stormwater conveyances including ditches, pipes and swales;
stormwater inlets and outfalls, building locations, locations of all existing
structural and source control BMPs, the location and extent of significant
structures and impervious surfaces, and the percentage of each drainage
area that is impervious), and the drainage areas for each outfall. The site
map (or alternatively the general location map) shall identify whether any
receiving waters are impaired (on the state's 303(d) list of impaired
Page 5 of 45

Permit No. NCS000588
waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(iv) Locations of any storage piles containing salt used for deicing or other
commercial or industrial purposes. Storage piles of salt or piles containing
salt used for deicing or other commercial or industrial purposes, must be
enclosed or covered to prevent exposure to precipitation. The permittee
must implement appropriate measures (e.g., good housekeeping, diversions,
and/or containment) to minimize exposure resulting from adding to or
removing materials from the pile. Piles do not need to be enclosed or
covered only if stormwater from the pile is not discharged directly or
indirectly to waters of the United States or discharges from the piles are
authorized and controlled under another NPDES permit.
(v) Locations of aircraft and runway deicing operations; fueling stations;
aircraft, ground vehicle and equipment maintenance/cleaning areas;
storage areas for aircraft, ground vehicles and equipment awaiting
maintenance.
BMPs. The SPPP shall contain a narrative description of the BMPs employed which
control or minimize the exposure of significant materials to stormwater, including
structural and nonstructural measures. The SPPP shall describe the type, location
and implementation of all BMPs for each area where industrial materials or
activities are exposed to stormwater.
BMP Summary. The BMP Summary shall include a written record of the specific
rationale for installation and implementation of the selected site BMPs. The
installation and implementation of BMPs shall be based on the assessment of the
potential for sources to contribute significant quantities of pollutants to stormwater
discharges. The BMP Summary shall be reviewed and updated annually
k. Feasibility Study. The SPPP shall include a review of the technical and economic
feasibility of changing the methods of operations and/or storage practices to
eliminate or reduce exposure of materials and processes to stormwater. Wherever
practical, the permittee and co-permittees shall prevent exposure of all storage
areas, material handling operations, and manufacturing or fueling operations. In
areas where elimination of exposure is not practical, the SPPP shall document the
feasibility of diverting stormwater runoff away from areas of potential
contamination.
Sgcondgry CoiltainMCnt HgquiremCnt5 gnd RgcordS. Secondary containment is
required for: bulk storage of liquid materials; storage of Section 313 of Title III of
the Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals; and storage of hazardous substances, in order to prevent leaks and spills
from contaminating stormwater runoff. A table or summary of all such tanks and
stored materials and their associated secondary containment areas shall be
maintained. If the secondary containment devices are connected directly to
stormwater conveyance systems, the connection shall be controlled by manually
activated valves or other similar devices (which shall be secured closed with a
locking mechanism), and any stormwater that accumulates in the containment area
Page 6 of 45

Permit No. NCS000598
shall be at a minimum visually observed for color, foam, outfall staining, visible
sheens and dry weather flow, prior to release of the accumulated stormwater.
Accumulated stormwater shall be released if found to be uncontaminated by the
material stored within the containment area. Records documenting the individual
making the observation, the description of the accumulated stormwater, and the
date and time of the release shall be kept by the permittee and/or co-permittee, as
appropriate, for a period of five years. For facilities subject to a federal oil Spill
Prevention, Control, and Countermeasure Plan (SPCC), any portion of the SPCC plan
fully compliant with the requirements of this permit may be used to demonstrate
compliance with this permit.
M. Unauthorized Discharges. Discharges to waters of the United States that are not
authorized by this permit, or by another NPDES permit, or by other authorization or
permission are unlawful and must be eliminated. The SPPP must include a
certification by the permittee that all discharges (i.e., outfalls) have been tested or
evaluated for the presence of non-stormwater discharges, and that all unauthorized
discharges have been eliminated. The permittee shall re -certify annually that the
stormwater outfalls have been evaluated for the presence ol'non-stormwater
discharges. The permittee may require and rely on each co-permittee to certify
annually to the permittee that there have been no unpermitt:ed discharges to the
water of the United States. These certification statements will be signed in
accordance with the requirements found in Part 111, General Conditions, Section B,
Paragraph 5 and must include:
i The date of any testing and/or evaluation,
ii A description of the evaluation criteria or testing method used,
iii A list of the outfalls or onsite drainage points that were directly observed
during the test,
iv A description of the results of any test and/or evaluation for the presence of
non-stormwater discharges, i.e., identification of unauthorized discharge(s)
origin and composition,
v The action(s) taken to eliminate unauthorized discharge(s), if any were
identified. For example, a floor drain was sealed, a sink drain was rerouted
to sanitary, or an NPDES permit application was submitted for a cooling
water discharge.
n. Spill Prevention and Response Plan. The permittee shall develop and implement a
Spill Prevention and Response Plan (SPRP), which shall be part of the SPPP and
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility, and which the permittee shall provide to all co-permittees.
Facility personnel (or the team) responsible for implementing the SPRP shall be
identified in a written list incorporated into the SPRP. A responsible person shall be
on -site at all times during facility operations that have the potential to contaminate
stormwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site stormwater specific. Therefore, an oil
Spill Prevention Control and Countermeasure plan (SPCC) may be a component of
the SPRP, but may not be sufficient to completely address the stormwater aspects of
the SPRP. The common elements of the SPCC with the SPRP may be incorporated by
reference into the SPRP. Response procedures must include notification of
appropriate facility personnel, emergency agencies, and regulatory agencies, and
Page 7 of 45

Permit No. NCS000588
procedures for stopping, containing and cleaning up spills. Employees who may
cause, detect or respond to a spill or leak must be trained in these procedures and
have necessary spill response equipment available. Include contact information for
.individuals and agencies that must be notified in the event of a spill in the Plan and
in other locations where it will be readily available.
o. Preventative Maintengagg and Good Housekeeping Program. A preventative
maintenance and good housekeeping program (PMGH Program) shall be developed
and implemented, and any affected co-permittee, provided that the co-permittee
shall develop and implement its own PMGH Program to supplement the PMGH
Program developed by the permittee, provided that such co-permittee PMGH
Program shall be consistent with the permittee's PMGH Program. The permittee's
PMGH Program shall list all stormwater control systems, stormwater discharge
outfalls, all on -site and adjacent surface waters and wetlands, industrial activity
areas (including material storage areas, material handling areas, disposal areas,
process areas, loading and unloading areas, and haul roads), all drainage features
and structures, and existing structural BMPs; any co-permittee's PMGH Program
shall include any such information as is relevant or required by the permittee's
PMGH Program. All such PMGH Programs shall establish schedules of inspections,
maintenance, and housekeeping activities of stormwater control systems, as well as
facility equipment, facility areas, and facility systems that present a potential for
stormwater exposure or stormwater pollution. Inspection of material handling
areas and regular cleaning schedules of these areas shall be incorporated into the
PMGH Program. Timely compliance with the established schedules for inspections,
maintenance, and housekeeping shall be recorded in writing and maintained.
P. Employee Irgining. All plans shall include an employee stormwater training
program. The permittee must include a schedule for all types of necessary training.
Each co-permittee shall maintain its own training program and a records of its
training program, which shall be consistent with the permittee's training program.
All permittee and co-permittee employees who work in areas where industrial
materials or activities are exposed to stormwater, or are responsible for
implementing activities identified in the SPPP (e.g., inspectors, maintenance
personnel), must participate in annual training. Training must cover the
components and goals of the SPPP, and include spill response, good housekeeping,
material management practices, and BMP operation and maintenance. The annual
training shall be documented by the signature and printed or typed name of each
person
q. Responsible-RaiU, The SPPP shall identify staff members (by name or title)
responsible for developing, implementing, maintaining, revising and ensuring
compliance with the SPPP. Specific responsibilities of each staff individual must be
identified and listed in SPPP. Co-permittees shall provide the same information to
the permittee in a timely fashion.
FilcilitInspections. Inspections of the facility and all stormwater systems shall
occur as part of the Preventative Maintenance and Good Housekeeping Program at a
minimum on a semi-annual schedule, once during the First half of the year (January
to June), and once during the second half (July to December), with at least 60 days
separating inspection dates (unless performed more frequently than semi -
Page 8 of 45

Permit No. NCS000588
annually). The Director may require increased inspections and SPPP re-evaluations
as necessary. The inspection and any subsequent maintenance activities performed
shall be documented, recording date and time of inspection, individual(s) making
the inspection, and a description of the facility's stormwater control systems,
equipment, and systems. The permittee can inspect any co-permittee facility in
implementing this program, but co-permittees must develop and implement their
own Preventive Maintenance and Good Housekeeping Program as appropriate for
their facility, but, in any event, if requested by the Director or the permittee.
3. Implementation. The permittee shall implement the SPPP and each co-permittee
shall implement such SPPP as it is required to prepare and implement under this
permit. Implementation of the SPPP shall include documentation of all monitoring,
measurements, inspections, maintenance activities, and training provided to
employees, including the log of the sampling data and a record of actions taken to
implement BMPs associated with the industrial activities. Such documentation
shall be kept on -site for a period of five years and made available to the Director or
the Director's authorized representative immediately upon request. The permittee
must maintain all BMPs in effective operating condition at all times. Failure to do so
is a violation of this permit. The SPPP must describe procedures and a regular
schedule for preventive maintenance of all BMPs, including the amount of time
required for maintenance and repair, and what back-up practices are in place
should a run-off event occur while a BMP is off-line. Nonstructural BMPs must also
be diligently maintained (e.g., spill response supplies available, personnel trained).
BMPs that are not operating properly must be repaired before the next anticipated
storm event. If maintenance prior to the next storm event is not possible,
maintenance must be completed as soon as possible, and the permittee must
document the justification for the extended repair schedule. In the interim, the
permittee must have back-up measures in place to ensure that the quality of the
stormwater discharge is not diminished. The permittee must document all BMP
maintenance and repairs. Dates of regular maintenance should be documented. For
repairs, the date of deficiency discovery and the date on which the BMP was
restored to full -function should also be documented.
a. The permittee and co-permittees shall review and amend the SPPP whenever there
is a change in design, construction, operation, or maintenance which has a
significant impact on the discharge, or potential for discharge, of pollutants to
surface waters; routine inspection or compliance evaluation determines
deficiencies in BMPs; an inspection by a local, State, or Federal official determines
that modifications to the SPPP are necessary; or there is a spill, leak or other
release; or any time there is an unauthorized discharge. The permittee shall provide
copies of any amended Plan to co-permittees SPPP to the Director and all co-
permittees, and co-permittee shall provide a copy of any amended plan to
permittee. Permittee may provide a copy of any co-permittee's plan to the Director.
New co-permittees shall provide certification of non -in writing of receipt of the plan
and the absence of stormwater discharges.
b. All aspects of the SPPP shall be reviewed and updated on an annual basis. The
annual update shall include an updated list of significant spills or leaks of pollutants
for the previous three years, or the notation that no spills have occurred. The
Page 9 of 45

Permit No. NCS000588
annual update shall include re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a re-evaluation of the effectiveness of the BMPs listed in the BMP Summary
of the Stormwater Management SPPP,
C. SPPP modifications must be made within 30 calendar days after discovery,
observation or event requiring a modification. Implementation of new or modified
BMPs must be initiated before the next storm event if possible, but no later than 60
days after discovery, or as otherwise provided or approved by the Division. The
amount of time taken to modify a BMP or implement additional BMPs must be
documented.
d. If the SPPP modification is the result of a release or unauthorized discharge, the
permittee and/or co-permittee as appropriate, must document a description of the
release, the date of the release; the circumstances leading to the release and actions
taken in response to the release; and measures to prevent the recurrence of such
releases. Such documentation shall be kept on -site for a period of five years and
made available to the Director or his authorized representative immediately upon
request.
e. The Director may notify the permittee and co-permittees when the SPPP does not
meet one or more of the minimum requirements of the permit. The notification will
identify specific provisions of this permit that are not being met, and may include
required modifications to any plans stipulated deadlines, additional monitoring
requirements and special reporting requirements. The permittee and/or co-
permittee as appropriate, shall provide certification in writing (in accordance with
Part 111, General Conditions, Section B, Paragraph 5) to the Director that the changes
have been made.
f. A signature and date is required for any revisions to the SPPP.
A co-permittee may develop a SPPP for the discharges from the co-permittee's own areas of
the airport. Such SPPP shall be submitted to the Director and the permittee for review and
approval.
The permittee must retain a copy of the current SPPP required by this permit at the facility, and it
must be immediately available at the time of an on -site inspection.

Notes:
For each representative storm sampling event the total precipitation, storm duration, and
total flow must be monitored. Total flow shall be either:
(a) measured continuously, or
(b) calculated based on the amount of area draining to the outfall, the amount of
built -upon (impervious) area, and the total amount of rainfall (this method of
flow measurement should not be used for facilities with large runoff -collection
ponds); or
(c) estimated by the measurement of flow at 20-minute intervals during the rainfall
event.
The total number of samples during the permitting cycle shall reflect seasonable
variability.
Page l 1 of 45

Permit No. NCS000588
When possible the grab sample should be skimmed from the surface of a quiescent (calm
water) zone.
4. The Permittee shall monitor Propylene Glycol, Dissolved Oxygen and Ammonia during
three (3) discharge events each year (as available) at the time of de-icing/anti-icing or
during the next separate discharge event after de-icing/anti-icing. A discharge event is
defined as the runoff from precipitation in the form of snow, sleet, freezing rain or a rain
event following a frost sufficiently heavy to require aircraft be de-iced or anti -iced at the
airport. If, after the collecting a minimum of six (b) samples over a minimum of two (2)
consecutive seasons, dissolved oxygen is not reported below 5 mg/L, the Permittee may
reduce monitoring of dissolved oxygen and propylene glycol to one (1) sample annually.
If ammonia is not reported greater than or equal to 2 mg/L, ammonia may be reduced to

Permit No. NCS000588
SECTION E: MINIMIZATION OF THE DE-ICING MATERIALS IN STORMWATER
Facilities which conduct aircraft and/or runway (including taxiways and ramps) deicing/anti-icing
operations shall:
1. Evaluate present operating procedures to consider alternative practices that would reduce
the overall amount of deicing/ anti -icing chemical used and/or lessen the environmental
impact of the pollutant source.
2. Evaluate whether excessive application of deicing chemicals occurs and adjust as
necessary, consistent with considerations of flight safety.
3. Produce and implement a plan for the minimization of the release of materials used for
deicing into the stormwater system. This plan shall address, as a minimum:
a. The current use and practices employed at the airport for the control and
minimization of entry of the deicing materials into the stormwater system;
b. The means that may be practicable for modifying current use and practices to
collect the runoff that occurs during and following the application of the deicing
materials; and
C. Feasible alternatives to the use of urea and glycol -based deicing chemicals to reduce
the aggregate amount of deicing chemicals used and/or lessen the environmental
impact, consistent with considerations of flight safety.
4. Airport authorities must determine annually the usage rate of deicing/anti-icing chemicals
at their facility. The total amount of deicing/anti-icing chemicals used at an airport facility
is the cumulative amount used by the Airport Authority and each co-permittee of the
airport facility. In determining the fluid amounts of deicing/anti-icing chemicals used at a
facility, operators should use the pre -dilution volume.
Annual usage rate of deicing/anti-icing chemicals shall be reported annually to the state.
The Division may require facilities that conduct aircraft and/or runway (including taxiways
and ramps) deicing/anti-icing operations to apply for an individual permit.

a. If a facility has multiple discharge locations with substantially identical stormwater
discharges that are required to be sampled, the permittee may petition the Director for
representative outfall status. If it is established that the stormwater discharges are
substantially identical and the permittee is granted representative outfall status, then
sampling requirements may be performed at a reduced number of outfalls.
b. Qualitative monitoring for color, odor, solids, foam, outfall staining, visible sheens and
dry weather flow shall be performed at all stormwater discharge outfall locations. All
qualitative monitoring shall be documented and records maintained with the SPPP
Qualitative monitoring of stormwater outfalls does not need to be performed during a
representative storm event. Qualitative monitoring will be performed twice per year,
once in the spring (April -June) and once in the fall (September -November).
C. Stormwater samples collected to meet the analytical monitoring requirements of this
permit shall be collected from a discharge resulting from a representative storm event
unless otherwise specified. Failure to monitor storm events in accordance with the
specified frequency shall constitute a violation of this permit.
d. Detergents used outdoors shall be biodegradable. The pH of the discharge shall be in the
range of 6 to 9 standard units.
e. Analytical results from sampling during the final year of the permit term shall be
submitted with the permit renewal application.
f. This permit regulates stormwater discharges associated with industrial activity. Non-
stormwater discharges allowable in the stormwater conveyance system include:
(1) All other discharges authorized by an NPDES permit.
(2) Uncontaminated groundwater, foundation drains, air -conditioner condensate
without added chemicals, springs, waterline and fire hydrant flushing, water
from footing drains, flows from riparian habitats and wetlands.
(3) Discharges resulting from fire -fighting or fire -fighting training.
g. Glycol and Urea Usage. The permittee shall be responsible for summarizing the amount
of glycol (and urea if applicable) dispensed each month for de-icing/anti-icing activities,
and submit this data on an annual basis. This information shall be submitted with the
February monthly DMR, covering the previous calendar year.

Section G; Electronic Reporting of Reports [G,S,143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports and specify that, if a state does not establish a system to receive such submittals,
then permittees must submit monitoring data and reports electronically to the Environmental
Protection Agency (EPA). The final NPDES Electronic Reporting Rule was adopted and became
effective on December 21, 2015,
Note: This special condition supplements or supersedes the following sections within Part III of
this permit (Standard Conditions for NPDES Permits):
• Section B. (3.) Signatory Requirements
• Section D. (6.) Records Retention
• Section E. (1.) Discharge Monitoring Reports
• Section E. (2.) Submitting Reports
1. Reporting Requirements (Supplements Section E. (1.) and Supersedes Section E. (2.)l
Effective December 21, 2016, the permittee shall report discharge monitoring data
electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet
application.
Monitoring results obtained during the previous month(s) shall be summarized for each month
and submitted electronically using eDMR. The eDMR system allows permitted facilities to
enter monitoring data and submit DMRs electronically using the internet. Until such time that
the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting
Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to
the state electronically using eDMR and will be required to complete the eDMR submission by
printing, signing, and submitting one signed original and a copy of the computer printed eDMR
to the following address:
Central Files
Division of Water Resources
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above. See "How to Request a Waiver from Electronic Reporting" section
below.
Regardless of the submission method, the first DMR is due no later than 30 days from the
date the facility receives the sampling results from the laboratory.
2. How to Request a Waiver from Electronic Reportine
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain
an electronic reporting waiver, a permittee must first submit an electronic reporting waiver
Page 29 of 45

Permit No. NCS000588
request to the Division. Requests for temporary electronic reporting waivers must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the
date the facility would be required under this permit to begin submitting monitoring data and
reports. The duration of a temporary waiver shall not exceed 5 years and shall thereupon
expire. At such time, monitoring data and reports shall be submitted electronically to the
Division unless the permittee re -applies for and is granted a new temporary electronic
reporting waiver by the Division. Approved electronic reporting waivers are not transferrable.
Only permittees with an approved reporting waiver request may submit monitoring data and
reports on paper to the Division for the period that the approved reporting waiver request is
effective.
