Please find attached the National Pollutant Discharge Elimination System (NPDES) Stormwater Individual
Permit Coverage Renewal Form for the Matheson Tri-Gas, Inc. (Matheson) facility that is located at 326
Forestville Road, Wake Forest, Wake County, North Carolina.
Matheson acquired the facility on September 9, 2016 and requested that the stormwater permit be transferred
on August 11, 2016. At the time of acquisition, Matheson believed that the permit renewal application,
which was due May 30, 2016, had already been submitted. The omission in the renewal submittal was not
identified until Matheson requested a permit status update from the facility on May 15, 2017. Matheson has
prepared the attached application once the problem was identified.
Please do not hesitate to contact me if you have any questions or concerns either via electronic mail at
[e-mail] or by telephone at 931-296-8151.

BMPS Y

STORMWATER POLLUTON PREVENTION
BEST MANAGEMENT PRACTICES
NON-STRUCTURAL BMPS
Minimize exposure
Wherever possible, industrial materials and activities are located indoors to minimize exposure to
precipitation. An up-to-date inventory is maintained by the Plant Manager, so supplies may be
ordered only as needed. Metal equipment that is stored outdoors is regularly inspected for
materials showing signs of deterioration or rusting and will be scheduled for prompt removal or
relocation to areas where debris, metals, and other pollutants will not contaminate storm water.
Outdoor materials storage areas will be maintained in good condition and according to good
housekeeping practices. Solid wastes are disposed in containers located inside the building, then
transferred to dumpsters outdoors or directly into dumpsters that are stored outdoors. All
dumpsters have a watertight cover that should be kept closed at all times other than when disposing
of materials. Water or residue from truck washing activities is prohibited from being discharged
into stormwater outfalls. Handling procedures have been developed for the materials used at the
site to minimize exposure to stormwater.
Good Housekeeping
Exposed areas of the facility are kept clean and orderly. Areas around trash containers, storage
areas, and loading/unloading areas are observed daily and swept/cleaned as needed. Storm sewer
inlets are kept clear of debris, dirt, and wastes. Garbage and waste materials are picked up on a
regular schedule by waste management vendors. Drums, tanks and containers are observed daily
during operations for leaks or conditions requiring corrective actions.
Preventative Maintenance
Preventative maintenance inspections are conducted on a quarterly basis, in conjunction with the
visual inspections, to ensure that all structures and equipment remain in good condition.
Spill Response
This facility has designated individuals who are responsible for the facility's discharge prevention
program. An Emergency Notification List is maintained. Trained personnel are authorized to
implement containment and cleanup actions that do not require the use of an outside contractor.
In the event of a spill, actions will be taken immediately to minimize further release. Cleanup
procedures are to be implemented after the spill is safely contained. Spill kits are located in the
Compressor Building. These kits remain stocked and are inspected regularly to ensure adequacy.
Delivery trucks are also equipped with spill kits.
Recovered materials will be disposed off -site by a licensed contractor in accordance with
applicable local, state and federal rules and regulations pertaining to disposal of hazardous and
non -hazardous wastes.
Erosion Control
Because areas of the site are stabilized, erosion and sedimentation should be minimal. When an
area of erosion is discovered, it will be stabilized with gravel or rock. If debris, silt, or sediment

buildup in the storm sewer inlet grates becomes excessive, the grate will be cleaned and silt fencing
or gravel may be placed around the inlets for protection.
Employee Training
SWPPP training is conducted on an annual basis. Records of training are documented and
maintained in each employee's personnel file. Documentation includes a description of the type
of training, employee information, the instructor, and date of completion. These records are kept
for a minimum of three years. The personnel training program is evaluated as needed to determine
the need for improvements or revisions. Training is provided to all personnel who may be involved
in the handling and storage of materials that have the potential for exposure to storm water. The
training program provides basic on-the-job training in the following areas and are described in
detail below.
• An introduction to the purpose and layout of the plant.
• Instruction on inspection, monitoring, and maintenance procedures.
• A summary of spill prevention and response procedures, and the specific function of each
employee during the implementation of these measures.
• An overview of water pollution laws applicable to the facility.
• A discussion on the importance of good housekeeping and material management practices.
• An overview of handling procedures and safety concerns associated with the cryogenic
liquids generated and stored on -site.
• A discussion on the conditions of the NPDES storm water discharge general permit.
Dust Generation and Vehicle Tracking
The potential for dust generation from vehicles is minimized by concrete covering traffic areas.
Vehicles entering and leaving the facility are mainly cars and product delivery trucks. The
entrance to the facility and the road and routes inside the facility are paved. Site surfaces not
covered with concrete are covered with gravel; therefore, dust or particulate control is unnecessary.
The raw material is air, the final products are cryogenic liquids, and waste materials are kept in
the enclosed containers at designated locations. Therefore, there are not off -site tracking of raw,
final, or waste materials. Also, the generation of dust is minimal due to the nature of operations.
Inspections
Secondary containment systems are visually inspected. All accumulated stormwater must be
inspected prior to discharge from containment areas.
STRUCTURAL BMPS
Water treatment chemicals are stored in the pump house. These chemicals may include Chemical
Treatment CL4658, CL41, and Sodium Hypochlorite. Any spills will be collected in a pit within
the building. No materials within the building will be exposed to storm water.
