1.0 Introduction: Work is to be accomplished for the U.S. Environmental Protection Agency, Triangle, NC, herein referred to as Client, through the General Services Administration (GSA), Federal Acquisition Service (FAS), Professional Services Division, Southeast Sunbelt Region 1.2 Scope/Background

The U.S. Environmental Protection Agency (EPA), Research Triangle Park, North Carolina is responsible for procuring, testing, and distributing filters of high purity to the State/local air pollution control agencies. The quartz filters are used with a size selective sampler (SSI) to collect Particulate Matter (P10) (particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers) samples. The glass fiber filters are used with a Total Suspended Particulate (TSP) sampler. The Teflon filters are used with a sampler to collect PM-2.5 (particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers) samples. This process assures filters with uniform characteristics and known quality assurance testing for the national particulate networks.

1.3 Objective

The objective of this task order shall be to test Glass, Teflon, and Quartz filters to meet the regulatory standards as required by the EPA, see Section 2.0. Upon full acceptance ship those filters to various state and local air pollution control agencies TBD.

1.4 Task Order Type This task order will be firm fixed price.

The following procedures, references, and standards apply to the testing of filters. The contractor shall test a certain number of filters from the batch of Teflon, Glass, and Quartz filters provided by the manufacturer. A batch is defined as filters to be used in one calendar year. The contractor shall use a random number generator to select filters from the total delivery. All selected filters shall be subjected to the visual inspection tests and then a certain quantity (specified in charts below) shall be subjected to the other tests as described below. Only filters that pass the visual and physical testing shall be used for subsequent testing.

2.2.1 Additional Tests As required by 40CFR, Part 50, Appendix L. Tests shall be performed on 50 filters.

(1) Maximum moisture pickup: Not more than 10μg weight increase after 24-hour exposure to air of 40 percent relative humidity, relative to weight after 24-hour exposure to air of 35 percent relative humidity.

(2) Collection efficiency: Greater than 99.7 percent, as measured by the DOP test (ASTM D 2986-71) with 0.3μm particles at the sampler's operating face velocity.

(3) Filter weight stability: Filter weight loss shall be less than 20μg, as measured in each of the following two tests specified in 6.9.1 and 6.9.2 of Appendix L. The following conditions apply to both of these tests: Filter weight loss shall be the average difference between the initial and the final filter weights of a random sample of 50 test filters. The filters shall be weighed under laboratory conditions and shall have had no air sample passed through them (i.e., filter blanks). Each test procedure must include initial conditioning and weighing, the test, and final conditioning and weighing. Conditioning and weighing shall be in accordance with Part 50, Appendix L, and general guidance provided in the following reference:

REFERENCE

Quality Assurance Guidance Document 2.12, which can be found at http://www.epa.gov/ttn/amtic/files/ambient/pm25/qa/m212covd.pdf.

(4) Test for loose, surface particle contamination: After the initial weighing, install each test filter, in turn, in a filter cassette (Figure numbers L-27, L-28, and L-29 from Appendix L) and drop the cassette from a height of 25 cm to a flat hard surface, such as a particle-free wood bench. Repeat two times, for a total of three drop tests for each test filter. Remove the test filter from the cassette and weigh the filter. The average change in weight must be less than 20μg.

(5) Test for temperature stability: After weighing each filter, place the test filters in a drying oven set at 40 (C (2(C for not less than 48 hours. Remove, condition, and reweigh each test filter. The average change in weight must be less than 20μg.

(6) Alkalinity: Less than 25 micro equivalents/gram of filter, as measured by the procedure given in the above reference.

2.2.2 Trace Metal Analyses

The contractor shall analyze 50 filters for the trace elements listed below. The acceptance criteria is 90 percent (or 45 of the 50 filters) shall meet the following criteria. The average concentrations for the trace metals in 90 percent of the filters shall be less than the stated concentrations (which is twice the minimum detectable concentrations). The EPA shall reject the filters if any trace metal is ten times the minimum detectable concentration (or five times the concentrations stated below).

Maximum Concentration (ng/cm2) for Teflon Filters for XRF Analysis

2.3 Visual Inspection for Acceptance

The maximum number of rejects allowed for all physical characteristics combined is 6 percent. No defect is permitted for filter identification, and the maximum number allowed for the visual is 10 percent for defective filters and 5 percent for rejected filters.

The following descriptions of visual defects shall to be used in the acceptance inspection of the filters. Each filter is inspected, using a light screen or table or by viewing over a black surface, for the following defects:

(a) Pinhole - a small hole appearing (1) as a distinct and obvious bright point of light when examined over a light table or screen, or (2) as a dark spot when viewed over a black surface. Such a filter is considered a reject or unusable filter.

(b) Separation of ring - any separation or lack of seal between the filter and reinforcing ring. Such a filter is considered a reject filter.

(c) Chaff or flashing - any extra attached residual material on the ring or heat seal area which would prevent obtaining an airtight seal when the ring is placed under compression. Such a filter is considered a reject filter.

(d) Loose material - any extra loose material or dirt particles on the filter which would require removal by brushing prior to weighing. A filter with such a defect is considered a defective filter. Defective filters are considered usable.

(e) Discoloration - any obvious visible discoloration which might be evidence of a contaminant. Such a filter is considered a reject filter.

(f) Filter non-uniformity - any obvious visible non-uniformity in the appearance of the filter when viewed over a light table or black surface which might indicate graduation in porosity across the face of the filter or if the filter does not lay flat (e.g., laying in the petri dish). A filter with any such defect is considered defective.

(g) Other - a filter with any imperfections not described above, such as irregular surfaces or other results of poor workmanship may be considered defective.

2.4 Distribution of Filters to State and Local Air Pollution Agencies The contractor shall distribute filters, provided by EPA, to the state/local air pollution control agencies as soon as the testing has been completed and the filters are determined to be acceptable by EPA. The contractor shall transfer the appropriate number of filter boxes from the manufacture’s shipping cases to boxes provided by the contractor for distribution of the filters to the State/local air pollution control agencies nationwide. The contractor shall never ship a partial filter box. EPA will provide the contractor a master letter (one-sided, 10 page document). The contractor shall make copies of this letter and include one copy in each shipment to the agencies.

After the filters are distributed, it is anticipated there will be remaining boxes of filters (a box measuring approximately 16”x 20”x 14”). The contractor shall store the remaining filters until the PO notifies the contractor, in writing, to either a) send to state/local agencies whose filters were damaged in shipment or b) to dispose of them. If a state/local agency receives the filters from the contractor in a condition where contamination is suspected due to a shipping mishap and the contractor is notified, the contractor shall immediately notify EPA to get written consent to ship another set of filters to the participant.
