Dear Mr. Marsh:
DONALD R. VAN DER VAART
secmtory
Staff from the Department of Environmental Quality (DEQ) conducted a stormwater inspection on
November 20, 2015, as part of a multimedia inspection of your facility. Your assistance during the
inspection was greatly appreciated. The inspection report is attached. Findings during the inspection
were as follows:
1. Certificate of Coverage (COC) No. NCG160036 under NPDES General Permit NCG160000
was issued to Gelder & Associates. Incorporated to discharge stormwater runoff to an
unnamed tributary to Mills Branch, a Class C, NSW stream, in the Neuse River Basin.
2. The facility has developed,a stormwater pollution prevention plan (SPPP). A review of the
plan indicated that it included most components required by the general permit. However,
the following items were noted:
a) The plan has not been reviewed/updated annually as required by the General
Permit. Annual plan review/update must be documented.
b) Employee training has not been conducted and documented;
c) The General Permit in the stormwater file was an -expired version; please
replace it with a current effective version, which is available from DEQ website.
d) Secondary containments were provided to all above -ground storage tanks

(except for the 1000-gallon used oil tank (provided by Noble Oil), which has no
containment). Itwas noted that drain valves were left open at all containments.
Please ensure these valves are closed and locked. An inspection log shall be
developed to document visual inspections when stormwater from the
containments is released.
3. Semi-annual qualitative monitoring has' been conducted at one stormwater discharge outfall
(SDO1). However, four more SDOs.were identified during the site visit (see Figure 1).
As discussed during the inspection, runoff at SD05 could be diverted to SD02, runoff
at SD05 could be diverted to SDOL Once flow diversions are completed, qualitative
and analytical monitoring must be conducted at SDO1, SD02, and SD03. Outfall
locations shall tie marked on the updated site map. The facility also needs to develop a
log to document monthly usages of new motor oil.
4. Oil and grease accumulated on the ground were noted in the equipment power, wash area (see
Figure 1), process wastewater from the area was contained in a small catch basin, which was
almost full at the time of inspection. The wastewater generated in this area needs to be
appropriately,collected and treated, contaminated soil shall be removed. Please explain
in your response to this letter how you plan to properly dispose of the process,
wastewater.

(II) FACILITY DESCRIPTION: Gelder & Associates, Inc. (Gelder) operates a multiple fuel -fired drum hot mix asphalt
(HMA) plant in Wake County. The HMA plant is rated 350 tons per hour capacity, but is currently permitted to run up to 280
tons / hr resulting from a source test conducted in 2013. Established in 1996, plant currently operates 8 hr/day, 5 days/week.
Gelder employs —58 personnel, 6 of whom are actually involved in the daily operation of the asphalt plant.
Safety Notes: Be attentive to moving vehicles and conveyor belts when on site. Use standard safety equipment including a
hard hat, steel -toed shoes, safety glasses, and earplugs.
(111) INSPECTION SUMMARY: On March 27, 2015,1(Gary Perlmutter) with Thaddeus Valentine (DEMLR-RRO) and Cheng
Zheng (DWR-RRO) visited the Gelder HMA plant in Raleigh for a multimedia inspection addressing air and stormwater
media. This report addresses the air medium component of the inspection.
Upon approaching the facility, we detected no odors from the facility; we observed only a steam plume emitting from the
plant's baghouse stack. The weather was clear, but the site was wet from the previous day's rain. We met with Mr. George
Marsh, President and Authorized / Technical Contact. Mr. Marsh informed us that he had replaced the asphalt drum about a
year ago, and reconfigured the recycled asphalt plant equipment (i.e. conveyors and bins) in an effort to increase recycled
asphalt production up to 40%. 1 advised Mr. Marsh to consult with DAQ permitting staff to determine if this warrants a
pemdtmodification.
We reviewed the permit stipulations then toured the facility. The plant was operating, and while a steam plume was observed
from the baghouse, a particulate plume of about 15% VE was observed beyond the steam. Records were reviewed in the
plant control room, where a copy of the current permit was also seen tacked onto the wall. All required records appeared
complete and up-to-date.
Overall, the facility appeared to be maintained well from an air quality standpoint. Further details follow.

(Vlll) SOURCE TEST REVIEW: In its air compliance history, Gelder has record of two source testings:
• July 10, 1996 (original test) — the asphalt plant was tested for compliance with NSPS Subpart 1. The opacity average
during the testing was 7.3% (limit 20%) and the measured particulate emission rate was less than one third of the
emission limit.
• June 6, 2013 — This source testing was at DAQ request for compliance with current permit stipulations A.3
(Particulate Control from Hot Mix Asphalt Plants) and A.6 (NSPS Subpart 1). The request was triggered by a series
of VE emissions observations from the Asphalt Plant's stack over the past three inspections. Compliance was
demonstrated.
(IX) COMPLIANCE HISTORY: Gelder & Associates has the following compliance history:
• April 15, 2015 — an NOD was issued for unpermilted fuel type and recordkeeping.
• March 19, 2015 — an NOD was issued for a late annual report.
• December 8, 2011 — an NOD was issued due to a late permit renewal package.
• April 27, 2010 — an NOV was issued for a B.6 violation due to high emissions from the bagfilter stack.
• March 6, 2006 — an NOV was issued to this facility for failure to submit an updated Risk Management Plan.
• May 30, 2003 — an NOV/NRE was issued for another late quarterly report.
• October 23, 2002 — an NOV was issued for a late quarterly report.
(X) CONCLUSIONSIRECOMMENDATIONS, At the time of the inspection, Gelder & Associates Inc. appeared to be in
compliance with its permitting requirements with two deficiencies noted. It is recommended that the facility be re -inspected
in one year.

II1. SITE ASSESSMENT
1. Chemical Inventory
Gelder & Associates' SPPP
October 1999
Page 12
A review and inventory of the facility raw material information, supplied by Gelder &
Associates, was performed and is summarized in Table 2. The table outlines the
purpose/use, quantity used and stored on -site, and the likelihood of stormwater contact
for each material.
Chemical Inventory materials that are exposed to stormwater contact are further
described in Table 3.
2. Potential Pollutant Evaluation
The potential for stormwater contact with pollutants exists at locations around the
facility. A visual inspection of the facility by Applied Water Technology (AWT) on
September 2, 1999 and October 7, 1999 revealed the following potential pollutant areas:
Area 1
A fueling station is located in this area and contains two 6,000 gallon and one 3,000
gallon diesel fuel. These three tanks have secondary containment. There is the potential
for oil and grease buildup from trucks used in this area for filling or emptying of the
tanks. Two propane tanks, 1,000 gallons and 500 gallons, are also located in this area.
Since propane is a gas there is no potential for stormwater contamination. Two liquid
asphalt tanks, empty and partially underground, are located in this area. There is minimal
potential for stormwater contact with these tanks or residues from these tanks. Truck
washing is performed on a concrete pad located between the propane tanks and diesel oil
tanks in this area. A storage structure that contains the 55 gallon barrels of steam cleaner
is located between the washpad and diesel oil tanks in this area.
Runoff from Area 1 flows south into the pond (pond #2) on the southwest side of the
property. The pond ultimately discharges into Middle Creek.

Gelder & Associates' SPPP
October 1999
Page 13
Area 2
Truck parking and accumulated piles of miscellaneous metal debris are located in this
area. There is the potential for oil and grease buildup from trucks with leaks to
accumulate on the ground in this area. An uncovered dumpster filled with miscellaneous
debris from the office and shop area. The potential also exists for stormwater to contact
residues from the debris in the dumpster and accumulated piles in this area. A 7,500
gallon tanker of tacking solution is located in this area.
Runoff from Area 2 flows south into the pond (pond #2) on the southwest side of the
property. This pond ultimately discharges into Middle Creek.
Area 3
A maintenance shop and asphalt release station is located in this area. A 400 gallon
hydraulic oil tank, 400 gallon motor oil tank, 200 gallon gear oil tank, and 55 gallon
drums of numerous products such as aluminum brite are stored inside the maintenance
shop. A 125 gallon underground waste oil tank located on the southern side of the
maintenance shop collects the sanitary wastes and waste liquids to be disposed of from
the facility. Noble oil periodically empties the waste oil tank. The asphalt release station
is used to rinse out excess buildup from the trucks. At most, two 55 gallon barrels of
release agent are located at this station. Trucks park in this area while excess residues are
being removed at the asphalt release station or while being serviced at the maintenance
shop. There is the potential for oil and grease buildup from trucks with leaks to
accumulate on the ground in this area.
Runoff from Area 3 flows south/southwest into the pond (pond #2) on the southwest side
of the property. The pond ultimately discharges into Middle Creek.
Area 4
This area includes the actual asphalt plant operation facility. A 10,000 gallon diesel oil
tank, 30,000 gallon propane tank, 30,000 liquid asphalt tank, and a 750 gallon heat
transfer oil station in this area. The diesel fuel tank has secondary containment. Since
propane is a gas there is no potential for stormwater contamination. There is minimal

Gelder & Associates' SPPP
October 1999
Page 14
potential for stormwater contamination from the liquid asphalt tank. The liquid asphalt
solidifies quickly when released from the tank. Large sand and aggregates are piles are
located in this area. Trucks park in this area while being filled with the asphalt mixture.
There is potential for oil and grease buildup on the ground from trucks with leaks.
Runoff from Area 4 flows south and collects in a ditch, along the south side of the asphalt
plant operations, and flows west into the pond (pond #2) on the southwest side of the
property. The pond ultimately discharges into Middle Creek.
Area 5
The laboratory is located in a renovated house between the asphalt plant operations area
and the pond on the south southeast side of the facility. A propane tank used for space
heat is located in this area. Trucks park on the path on the west side of pond #1 and are
filled with water from the pond. There is the potential for oil and grease buildup from
trucks with leaks to accumulate on the ground in this area.
Runoff from Area 5 flows south into the south southeast pond (pond #1) and then flows
west through a pipe into the pond (pond #2) on the southwest side of the property.

3. Existing Management Practices
There are numerous areas at the facilities that already employ measures that reduce
stormwater contact with significant materials and activities. These areas are as follows:
Area 1
The three diesel oil tanks have secondary containment provided to contain any spills
while loading or unloading the tanks. The steam cleaner soap is located inside a storage
structure to reduce the potential for stormwater contact.
Area 3
The hydraulic oil, motor oil, and gear oil tanks are kept in the maintenance shop, which
eliminates the potential for stormwater contact.
Area 4
The diesel fuel tank has secondary containment provided to contain any spills while
loading or unloading. A baghouse is being used to collect airborne particles generated as
a result of material handling operations.

4. Existing Monitoring Data
There is no existing stormwater monitoring data available. All stormwater monitoring
data will be collected in the future under the requirements of the general stormwater
permit. A rain gauge has been installed and will be used to monitor precipitation.
5. Spill Incidents
As required by regulation, an audit of all spills and leaks was completed for the past 3
years. No spills have occurred at this facility in the three years prior to issuance of
Gelder & Associates' general stormwater permit as defined in Table 4.

IV. BEST MANAGEMENT PRACTICES
Best Management Practices (BMPs) address potential pollutant areas that were identified
during the facility site assessment. The BMPs are designed to help reduce the potential
for stormwater pollution. Recommended BMPs for the previously identified areas are as
follows:
Area 1
There is obvious oil and grease accumulated on the ground in this area. The soil in this
area that has been contacted by oil and grease should be removed and disposed of
properly. Berms and ditches should be provided to divert runoff from this area to reduce
the amount of stormwater contacting the pollutants in this area. Periodic inspections of
the containment structures in this area should be conducted for evidence of corrosion. It
is recommended that the wash water be collected and piped into the underground waste
oil tank and disposed of properly.
Area 2
A cleaning schedule should be established to periodically clean up debris and place into
an appropriately segregated storage area. It is recommended that the dumpster in this
area be covered to protect the waste materials inside from exposure to stormwater. Drip
pans should be placed under the trucks parked in this area to collect any oil drippage.
Area 3
The hydraulic oil, motor oil, and gear oil tanks should continue to be kept inside the
maintenance shop. Periodic inspections of the tanks should be conducted for evidence of
corrosion. The asphalt release station area should be located on a concrete surface and
berms or ditches constructed to direct flow into a collection tank to be disposed of
properly.

Gelder & Associates' SPPP
October 1999
Page 22
Area 4
Periodic inspections of the tanks and containment structure should be conducted for
evidence of corrosion. Berms and ditches should be provided to divert runoff around the
piles of sand and aggregates in this area to reduce the amount of stormwater contacting
the pollutants in this area. The hot oil transfer station should be covered to reduce the
potential for stormwater contact with any residuals on the equipment.
General
Best Management Practices for the site in general will include regular comprehensive
facility inspections, maintaining an updated material inventory, and ensuring that current
MSDSs are readily available. All employees shall be trained in spill response and good
housekeeping practices. Adequate supplies of materials for dry clean up of spills and
leaks should be kept readily available to all areas.
Additional BMP's
These additional BMPs could be implemented to further reduce or eliminate the potential
for stormwater contact. Some of these additional BMPs were recommended for site
specific pollutant areas; however, utilization of these BMPs facility wide could further
reduce the potential for stormwater contact.
Material storage, handling, and processing
• Cover material storage and handling areas with an awning, tarp or roof. Practice
good stockpiling practices such as: storing materials on concrete or asphalt pads;
surrounding stockpiles with diversion dikes or curbs; and revegetating areas used for
stockpiling in order to slow runoff.
• Use curbing, diking or channelization around material storage, handling and
processing areas to divert runon around areas where it can come into contact with
materials stored or spilled on the ground.
• Utilize secondary containment measures such as dikes or berms around asphalt
storage tanks and fuel oil tanks.
• Use dust collection systems (i.e. baghouses) to collect airborne particles generated as
a result of material handling operations or aggregate drying.

Gelder & Associates' SPPP
October 1999
Page 23
• Properly dispose of waste materials from dust collection systems and other
operations.
• Remove spilled material and dust from paved portions of the facility by shoveling or
sweeping on a regular basis.
• Utilize catch basins to collect potentially contaminated stormwater.
• Implement spill plans to prevent contact of runoff with spills of significant materials.
• Clean material handling equipment and vehicles to remove accumulated dust and
residue.
• Use a detention pond or sedimentation basin to reduce suspended solids.
• Use an oil/water separator to reduce oil/grease.
Erosion and sediment control:
• Trap sediment at downgradient locations and outlets serving unstabilized areas. This
may include filter fabric fences, gravel outlet protection, sediment traps, vegetated or
riprap swales, vegetated strips, diversion structures, catch -basin filters,
retention/detention basins or equivalent.
• Runoff containing oil and grease may include the use of absorbent booms or sand
filters in front of outlet structures or other equivalent measures.

V1. STORMWATER POLLUTION PREVENTION PLAN EVALUATION
1. Semi -Annual Site Compliance Evaluation
The facility site assessment and best management practices must be regularly updated
through semi-annual site compliance evaluations. Semi-annual evaluations should be
documented and a copy of the report placed in the facility files with the SPPP. Semi-
annual site compliance evaluations shall include the following:
• Inspect stormwater drainage areas for evidence of pollutants entering the drainage
system.
• Evaluate the effectiveness of Best Management Practices (BMPs).
• Observe any structural measures, sediment controls, or other stormwater BMPs to
ensure proper operation.
• Prepare a summary report of inspection results, including the date and inspector's
name, signature, and recommended follow-up actions.
2. SPPP Revisions
This Stormwater Pollution Prevention Plan shall be reviewed and/or amended
within two weeks of:
-Revision of applicable regulations.
-Changes in facility design, construction, operations, or maintenance which
materially affect the potential for stormwater contact of significant materials.
-Identification of an SPPP deficiency or recommendation of follow-up measures
during annual site compliance evaluation inspections.
-Notification from the State that the plan does not meet a minimum requirement
of the permit.
The plan shall be reviewed at least once every year and shall be amended if such review
indicates that the plan does not reflect current operations or physical facility features or is
deficient in any way.

Gelder & Associates' SPPP
October 1999
Page 35
3. Record Keeping and Internal Reporting
Records of all facility inspections and training should be kept in the facility files with the
SPPP for a period of five years. All documentation should include the name and
signature of the reporter and the date of the incident or inspection. Spill and incident
reports should also include a description of the incident, weather conditions, cause, and
any resulting environmental problems. The following records should be maintained with
the SPPP:
I. Facility inspections,
2. Spill reports,
3. Site evaluations,
4. Employee training,
5. Stormwater sampling,
6. Facility and equipment maintenance,
7. Sampling data, and
8. BMP implementation.
4. EPCRA, Section 313 Chemicals
If the facility is subject to reporting under EPCRA, Section 313 for water priority
chemicals, the SPPP must be reviewed and certified by a Registered Professional
Engineer and recertified every 3 years or after the plan is significantly changed.
This certification that the plan was prepared in accordance with good engineering
practices does not relieve the facility owner or operator of responsibility to prepare and
implement the plan.
