Re: NPDES Permit Application
Linde Gas North America, LLC.
11 Triangle Drive
Research Triangle Park, NC 27709
Dear Mr. Pickle.
rOWJ1
LJAN • - 2 2014
WA AL
Branch
On behalf of Linde Gas North America LLC, EA Engineering, Science, and Technology (FA) is
submitting the National Pollutant Discharge Elimination System (NPDES) permit application for the
facility located at 1 I Triangle Drive, Research Triangle Park, NC 27709. Also, included with the permit
application is the application fee of $860.00,
As requested during your conversation with EA on December 4, 2013, this application is being submitted
without the required sampling data for each outfall. In order to address the lack of sampling data,
information regarding the processes and materials at the facility has been included in order to identify
potential pollutants which may be present in stormwater runoff from the facility.
The primary function of the Linde Gas facility located at 1 1 Triangle Drive is the transfill and ultrasonic
testing of compressed gas cylinders. The primary materials at the facility are gases, which in in the event
of a release are assumed to evaporate and would not contact stormwater. In addition to gases, the facility
does use some liquid and solid materials in the industrial production processes.
Liquid materials onsite which may be exposed to stormwater include caustic (25% solution) which is
stored outdoors in 55 gallon drums on spill containment pallets. Solid materials stored at the facility
which are exposed to stormwater include scrap metals and compressed gas cylinders. Scrap metals are
stored in open dumpsters which are located in the employee parking area and in the area located behind
Building 184. Compressed gas cylinders are stored throughout the facility.
Small amounts of hazardous waste are also produced by the facility through various processes, however;
once it is produced it is collected by the facility's dust collector. The dust collector is located outdoors
and is ground -mounted. Dust is collected in 55 gallon drums which are placed on spill containment
pallets. Wastes contained within the drums have the potential to contain arsenic particulates.

Based upon the information provided, EA is requesting that the permit application be considered
complete without analytical information from each outfall.
If you have any questions or require any additional information, please contact Ms. Casey Keener at 410-

The drainage area to Outfall 3 receives stormwater from the process area along the southern and eastern edge of Building 184.
Activities in this area which are exposed to stormwater include an outdoor dust collector. Wastes collected in the dust
collector have the potential to be hazardous. Significant materials stored in this area include caustic (25% solution) which
held in 55 gallon drums and is stored outdoors on secondary containment pallets. The facility hazardous waste storage area is
also located in this drainage area. Hazardous waste are stored undercover and within secondary containment.
C. For each outfall, provide the location and a description of existing structural and nonstructural control measures to reduce pollutants in storm water runoff; and a
description of the treatment the storm water receives, including the schedule and type of maintenance for control and treatment measures and the ultimate disposal
of any solid or fluid wastes other than by discharge.

Subject: Permit Status for Linde Gas Research Triangle Park Facility
Ken,
As a follow up, thanks again for looking into the permit status for the Linde Gas Research Triangle Park Facility. As I
mentioned, I am taking over this project, so please send future communications to me. Feel free to email or call me if
you have any questions!
Thanks again, and I if I don't hear anything, I will give you a follow-up call around April 1".
