IDIQ Contract Scope of Services

1. Introduction and Background

1.1 Introduction

The National Park Service (NPS) is responsible for the protection and enhancement of air quality related resources in the areas it manages by ensuring compliance with directives, regulations, and applicable requirements of the NPS Organic Act of 1916 and the Clean Air Act. The Organic Act mandates the National Park Service to:

"...conserve the scenery and the natural and historic objects and the wildlife therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations."

The Clean Air Act affords special air quality protections to certain national parks and wilderness areas, designating them as mandatory Class I federal areas, and assigns to the Federal Land Managers (FLMs) of those areas "the affirmative responsibility to protect the air quality related values (including visibility)" of Class I lands. It also established "as a national goal the prevention of any future, and the remedying of any existing, impairment of visibility in mandatory Class I federal areas which impairment results from manmade air pollution." The Clean Air Act established a detailed program that provides guidance to the NPS in meeting these mandates.

On behalf of the NPS, the Air Resources Division (ARD) has an air quality program to carry out these responsibilities; this involves a wide range of activities, including air quality monitoring and modeling, technical review of Prevention of Significant Deterioration (PSD) permit applications, coordination with states and other federal agencies, analyses of air quality related values inventories and effects, and special studies focused on source apportionment, ecological impacts and visibility perception.

The National Park Service administers 48 parks and wilderness areas that are designated Class I, the U.S. Fish and Wildlife Service (FWS) administers 21 Class I wilderness areas, the U.S. Forest Service (USFS) administers 88 Class I wilderness areas and there is one international park that is Class I. Of these 158 mandatory Class I federal areas, visibility is considered an important attribute in all but two USFS wilderness areas. Visibility-protected Class I areas are to be protected from air pollution impacts on visibility.

Document Title IMPROVE Network Operations and Filter Analysis Indefinite Delivery Indefinite Quantity (IDIQ) Contract

The Regional Haze Rule (RHR) establishes the regulatory framework by which the national visibility goal is to be met [United States Environmental Protection Agency, 1999] and requires monitoring representative of the 156 visibility-protected Class I areas. The monitoring guidance, used to support the RHR, specifies particle sampling and analysis of the major aerosol components using methods patterned after those utilized since 1987 by the Interagency Monitoring of Protected Visual Environments (IMPROVE) program [Joseph et al., 1987; Malm et al., 1994]. The IMPROVE program is a cooperative measurement effort managed by a Steering Committee that consists of representatives from the U.S. Environmental Protection Agency (EPA), the NPS, the USFS, the FWS, the Bureau of Land Management (BLM), the National Oceanic and Atmospheric Administration (NOAA), four organizations representing state air quality organizations (the National Association of Clean Air Agencies, the Western States Air Resources Council, the Northeast States for Coordinated Air Use Management, and the Mid-Atlantic Regional Air Management Association), and three Associate Members: the State of Arizona Department of Environmental Quality, Environment Canada, and the South Korea Ministry of Environment. The IMPROVE program is designed to establish current visibility and aerosol conditions in mandatory Class I areas; to identify chemical species and emission sources responsible for existing man-made visibility impairment; to document long-term trends for assessing progress toward the national visibility goal; and with the enactment of the RHR, to provide regional haze monitoring representing all visibility-protected federal Class I areas where practical. The IMPROVE program oversees the RHR monitoring efforts.

The National Park Service manages the IMPROVE monitoring efforts on behalf of the Steering Committee. This solicitation is sponsored by the NPS but covers the monitoring efforts for all mandatory Class I federal areas, as well as other monitoring using the IMPROVE monitoring protocols (described further below). The successful offeror of this solicitation will work through the NPS on all contractual related matters; other agencies sponsoring IMPROVE monitors will work through the NPS to access the resources available through this contract.

1.2 Background

IMPROVE was established as a national visibility monitoring program in 1985. The IMPROVE network initially was funded by the NPS and consisted of 30 monitoring sites primarily located in national parks, 20 of which began operation in 1987. IMPROVE network operations were fully implemented in March 1988. Beginning in 1998 the EPA provided supplemental support to IMPROVE to expand the network in order to provide representative particle speciation monitoring for all 156 visibility-protected Class I areas, as required under the RHR. In a site selection process which included input from all interested state air quality agencies, the IMPROVE Steering Committee identified locations for 110 monitoring sites that were deemed representative of the regional haze conditions for 155 of the mandatory 156 Class I areas (the Bering Sea Wilderness is the exception). Additional information about the site selection process is available elsewhere [Malm et al., 2000; http://vista.cira.colostate.edu/improve/].

In addition to the 110 IMPROVE network sites that are used to represent Class I areas, a number of IMPROVE protocol sites are currently in operation, mostly in rural locations, that provide expanded spatial coverage in regions outside of Class I areas. Protocol sites are separately sponsored by state, regional, tribal, and federal organizations and use the same instrumentation, monitoring, and analysis protocols as IMPROVE. The use of identical samplers and analysis protocols by the same Contractor ensures that data generated by IMPROVE and IMPROVE http://vista.cira.colostate.edu/improve/

Document Title IMPROVE Network Operations and Filter Analysis Indefinite Delivery Indefinite Quantity (IDIQ) Contract protocol sites can be treated as directly comparable. In total, there are 159 IMPROVE and IMPROVE protocol sites. Two of these sites (Lake Tahoe Community College and Baengnyeong Island, South Korea) are not funded as part of this contract and so should not be included in proposals; rather, technical and cost proposals should be prepared for 157 sites (110 IMPROVE and 47 IMPROVE Protocol sites) (See Attachment 2). Of the 157 sites, one of the sites is for Carbon analysis only (Detroit), and one site (Phoenix) has two samplers, such that there are a total of 158 samplers. Most sites are located in rural areas; however, for the purpose of comparing differences in aerosol composition between rural and urban areas, there are several urban sites (see Attachment 2). Likewise, to better facilitate inter-comparison and integration of IMPROVE data with EPA’s Chemical Speciation Network (CSN), six sites are collocated with CSN sites. Data from all IMPROVE sites are available on the Federal Land Manager Environmental Database (FED; http://views.cira.colostate.edu/fed/).

Map of 157 IMPROVE and IMPROVE Protocol Sites as of December 2019.

The RHR specifies that IMPROVE aerosol data be used to calculate the metric for tracking progress toward the goal of eliminating man-made visibility impairment for the visibility-protected Class I areas, with the ultimate goal of reaching endpoint (formerly natural background) conditions by 2064. As a result it is especially important to ensure that the IMPROVE aerosol monitoring and data processing procedures produce comparable data over a period of many decades so that credible haze trends can be determined.

To collect samples for the speciated particle measurements, the NPS currently employs a 4-channel (labeled A, B, C, and D) IMPROVE particle sampling system. A description of the current IMPROVE sampler and standard operating procedures can be found on the IMPROVE website http://views.cira.colostate.edu/fed/

Document Title IMPROVE Network Operations and Filter Analysis Indefinite Delivery Indefinite Quantity (IDIQ) Contract

(http://vista.cira.colostate.edu/improve/). The PM2.5 (particles <2.5 micrograms in diameter) samplers operate with a nominal flow rate of 22.8 liters/minute (LPM), while the PM10 sampler (particles <10 micrograms in diameter) runs at 16.9 LPM. Both collect samples for a 24-hour time interval, midnight to midnight local time, every third day. Channel A (PM2.5), operated with Teflon filters, is used for determining fine mass, elemental composition, and optical absorption. Elements to be determined from the analysis are given in Table 1, along with measurement detection limits and precision. Channel B (PM2.5) is operated with a nitric acid denuder and a nylon filter collection substrate. The nylon filter is analyzed for the anions nitrate, nitrite, sulfate and chloride. Channel C (PM2.5), operated using pre-fired quartz filters, is used to determine elemental and organic carbon using the thermal/optical reflectance technique. A complete description of this technique, including recent upgrades, is available in Chow et al. (1993; 2007; 2015). Channel D is operated with a Teflon substrate and PM10 inlet. The PM10 filters are analyzed for total mass. Laboratory blanks are also utilized for each of the channels, and field blanks are employed to better assess detection limits and potential contaminants in the samples. For further details on all measurements and analysis, see the IMPROVE website, and the pages describing standard operating procedures contained therein (http://vista.cira.colostate.edu/Improve/sops/).

2. Objective/Purpose The purpose of this contract is to (1) assist NPS in operating, maintaining and reconfiguring (where required) the IMPROVE particle monitoring network, which consists of 110 IMPROVE sites and 47 IMPROVE protocol sites; (2) analyze all exposed fine (PM2.5) and total (PM10) Teflon filters for mass concentrations; and (3) analyze PM2.5 Teflon filters for elemental concentrations of select elements (Table 1) and optical absorption; (4) coordinate analysis of nylon and quartz filters for ion and carbonaceous material, respectively1; (5) establish and conduct an internal quality assurance program; (6) participate in laboratory and field audits; and (7) provide a final, integrated dataset (including ion and carbon data, as well as associated metadata).

The Contractor is expected to employ established protocols in operating the IMPROVE network.

See the standard operating procedures (SOPs) for the monitoring program at the IMPROVE website (http://vista.cira.colostate.edu/Improve/particulate-monitoring-network/). As new methods are developed and enhanced quality control measures are defined, through activities funded separately from this contract, the Contractor shall incorporate these new methods into the IMPROVE routine operations through the modification of SOPs. Task Orders may require that the Contractor also ensure that all pertinent information (e.g., data, metadata, laboratory and field logs, etc.) developed by the Contractor for routine operations are available to other organizations as needed for their activities.

http://views.cira.colostate.edu/fed/

Document Title IMPROVE Network Operations and Filter Analysis Indefinite Delivery Indefinite Quantity (IDIQ) Contract

3.4.1 Gravimetric Analysis

The Contractor shall perform gravimetric analysis on the Teflon filters for the PM2.5 and PM10 samples. The desired minimum detectable limit for sample mass deposited on the filter is 10 micrograms or less. The anticipated upper limit for aerosol mass on the filter is 10,000 micrograms; this equates to ambient concentrations of ~400 micrograms m-3, sampled for 24 hours from the total (PM10) aerosol module. All gravimetric measurements shall be made in a temperature and relative humidity (RH) controlled environment. A mean temperature between 20 and 23 degrees Celsius and a mean RH between 30% and 40% should be maintained;

temperature and RH should be monitored to ensure a stable measurement environment. The Contractor's responsibilities shall include:

Pre-weigh Teflon filters prior to sending to sites; including field blanks;

Post-weigh Teflon filters upon receipt, including field blanks, and determine gravimetric mass from PM2.5 and PM10 Teflon filters to a precision of ± 3µg;

Perform routine measurements of laboratory blanks to assess short-term (<1 day) and long-term stability and performance of the instruments;

Perform routine measurements using one or more certified calibration standards;

Perform sufficient replicate weight analysis to determine measurement precision;

Report metadata related to the laboratory procedures and equipment.

3.4.2 Elemental Analysis

The Contractor shall perform non-destructive elemental analysis of filters by any of several equivalent techniques. Elemental mass shall be reported for fine mode Teflon filter samples for all of the elements listed in Table 1. Special consideration will be given to sensitivity levels of the following elements: Na, Mg, Al, Si, Cl, K, Ca, V, Fe, Ni, Cu, Zn, As, Se, Br, Pb. In addition to reporting elemental mass for each species, the Contractor shall:

Characterize the sensitivity, accuracy, and precision of the analytical techniques;

Perform replicate analyses on the network filters at a rate sufficient to establish measurement precision;

Routinely analyze laboratory and field blanks;

Document any changes to the analytical techniques or equipment;

Apply and document matrix corrections for all particle size and loading effects; and Archive and make available all metadata associated with the laboratory, field and data processing procedures needed to properly interpret and understand the quality of the delivered analytical data.

The method currently used to determine elemental composition is X-Ray Fluorescence (XRF).

Other, equivalent techniques may also be proposed. Technical proposals should address the suitability of the proposed analytical approach to determine masses for all elements listed in Table

1. Sensitivities also shall be indicated for each of the elements in Table 1. Quantitative and operational definitions shall be provided for the following quantities: accuracy, precision, and minimum detectable limit.

Because a primary goal of the IMPROVE network is to generate data that are suitable for long-term trends assessment, a proposal utilizing techniques other than XRF must address the issue of equivalence of data that would be generated by the proposed analytical systems to the data from the current analytical systems. NPS may require a demonstration of equivalence (i.e., results

Document Title IMPROVE Network Operations and Filter Analysis Indefinite Delivery Indefinite Quantity (IDIQ) Contract agreeing within specified uncertainties) on up to 50 actual IMPROVE network filter samples (reimbursed by NPS at posted commercial rates). The current analytical system’s precision and minimum detection limits (MDL) are given in Table 1. In the table, the analytical MDL is based on three times the standard deviation of 100 analyses of a single field blank filter. The analytical precision estimates are based on the root mean square sum of the standard deviations from 10 analyses of 18 different samples. Of the 18 samples used for the precision estimates, 16 were PM2.5 samples from the IMPROVE network and 2 were multi-element calibration reference filters.

For each sample, an element was only included in the precision estimate if the mean loading on the sample was greater than three times the detection limit, except for Zr, where the criterion was lowered to greater than the detection limit due to very low sampled masses.

Table 1. Detection limits and precision for elements to be analyzed based on the current IMPROVE analytical method of XRF. Precision is based on sample loadings >3 × MDL, except for Zr, which is only >MDL.

3.4.3 Optical Absorption Measurements

The Contractor shall perform optical absorption measurements on the PM2.5 Teflon filters. The current method to determine optical absorption is the Hybrid Integrating Plate/Sphere (HIPS;

White et al., 2016). Other, equivalent techniques may also be proposed. If an alternate technique is proposed, the proposal must address the issue of equivalence of data that would be generated by the proposed analytical systems to the data from HIPS.

The Contractor's responsibilities shall include calculation of absorption coefficients of the collected samples. For the current system, the minimum detectable limit is 0.34 x 10-6 m-1 and the precision of the measurement is 0.15 x 10-6 m-1. MDL and precision estimates should be included for all proposed systems.

4. Site Tasks Task Orders will be evaluated annually and negotiated with the intent to keep pace with and respond to emerging air pollution issues, as well as logistical and financial challenges associated with the monitoring program. For example, the total number of IMPROVE sites has changed over time, with sites being added, removed and/or relocated. Although such changes typically occur each year, the number and type of changes to the network varies. As such, tasks related to reconfiguration of the network are included here as Site tasks. Similarly, the NPS often carries out Special Studies, which may include a short term IMPROVE sampler and associated analysis;

such analysis is considered separate from the routine monitoring network, and as such is included as an Site task. The following tasks may be needed at any time during the period of performance of the IDIQ and will be issued as individual exercise of pre-priced tasks. Stand Alone Task Orders for Site tasks may include any combination of the tasks below at various levels of effort. Pricing for each of the Site tasks will be dependent on the level of effort required, and as such a summary of labor rates for relevant personnel will determine overall site task pricing.

4.1 Establishment of New Monitoring Site

The Contractor may be required to install a new or existing IMPROVE sampler at a new site. The Contractor must consider siting criteria and SOPs for IMPROVE, as described on the IMPROVE webpage (http://vista.cira.colostate.edu/Improve/sops/), and will be responsible for the following tasks for each additional site identified on Individual Task Orders:

Assist in selection of appropriate monitoring sites;

Supply and install necessary sampling structure for instrument installation;

Supply and install monitoring instruments and maintain them in operable condition; and Train agency personnel responsible for routine operation of instruments.

Spare IMPROVE samplers are available to the vendor on an as-needed basis which may be maintained at the Contractor site. These samplers can be used for new sites so long as a sufficient number are available to quickly respond to replacement and repair needs. The Contractor will inform the COR when the number of spare samplers is below the number deemed sufficient to maintain the network so that additional samplers may be procured.

Document Title IMPROVE Network Operations and Filter Analysis Indefinite Delivery Indefinite Quantity (IDIQ) Contract

4.2 Repair or Replacement of Site Due to Malfunction, Safety Concerns or Loss.

The Contractor may be required to repair or replace an IMPROVE sampler which has been damaged or destroyed. The Contractor must consider SOPs for IMPROVE, as described on the IMPROVE webpage (http://vista.cira.colostate.edu/Improve/sops/), and would be responsible for the following tasks for each site identified on the Task Order:

When practical, repair components of damaged IMPROVE samplers and/or sampling structures;

Supply and install necessary sampling structure for instrument installation; and Supply and install monitoring instruments and maintain them in operable condition.

4.3 Decommissioning Current Monitoring Stations

The Contractor may be required to decommission one or more sites. The Contractor would be responsible for the following tasks at any site that is designated by the Task Order to be decommissioned:

Arrange for a final calibration and document the condition of the site and equipment;

Arrange for the removal of the IMPROVE sampling equipment, to be maintained as spare equipment or parts for possible use elsewhere;

Arrange for the removal of site documentation (field logs); and As necessary, arrange for the removal of the site sampling structure.

4.4 Supply samplers, associated equipment, spare parts.

The Contractor may be required to supply or develop samplers or associated equipment/parts.

Efficient operation of the network requires that an adequate supply of backup modules and all associated equipment be kept on hand. The Contractor shall inform the CO and COR about the need for any supply of equipment that falls outside of the base Network Operations and Filter Analysis IDIQ contract.

4.5 Site operators.

Most sites are operated and maintained by state and federal agency personnel. Some sites may not have that provision. In such situations the Task Order may require the Contractor to obtain the services of an on-site operator.

4.6 Additional Analyses

Methods not included in this solicitation may be requested to measure additional species, including species measured in the past as part of the IMPROVE Network, or measurements of new species. Such efforts may include, but are not limited to, FTIR analysis of aerosol samples to determine functional groups and estimate total particulate carbon, or measurements of total carbon using alternate methods. Alternatively, the Contractor may be required to extend optical absorption measurements from filter substrates (currently HIPS) to include measurements at multiple-wavelengths, encompassing the near-infrared to ultraviolet. Analytical methods such as these, as well as others not explicitly noted here, may be implemented in future monitoring.

Please provide information regarding measurement capabilities for additional aerosol and gas phase phases species and properties relevant to the IMPROVE Program.

4.7 Special Studies

Document Title IMPROVE Network Operations and Filter Analysis Indefinite Delivery Indefinite Quantity (IDIQ) Contract

The Contractor may be required to participate in Special Studies, providing support for the deployment of samplers, coordination of filters with other NPS Contractors, and additional filter analysis. The Contractor may also be required to deploy additional measurement techniques relevant to the IMPROVE Program, including, particle and/or particle mass sensors, meteorological measurements, and light scattering and absorption measurements. As part of these efforts, the Contractor may be required to conduct daily analysis as outlined in specific, applicable Task Orders.

4.8 IMPROVE Outreach

The Contractor may be required to oversee outreach activities related to the IMPROVE Program.

These activities may include communication and recognition of site operators and program partners, as well as outreach activities intended for the general public. The Contractor may be required to develop and distribute materials, as outlined by the Task Order.

4.9 Change in Site Maintenance Schedule

The Contractor may be required to increase the frequency of site visits for routine maintenance and calibration as specified at the task order level.

4.10 Development of Measurement Methods

The Contractor may be required to develop methods to enhance current IMPROVE measurements or to allow for cost savings measures. Specifications for new methods will be provided by the Task Order requirement documents, and the Contractor is encouraged to recommend new methods and cost savings measures at any time during the life of the IDIQ contract.

4.11 Operation of Alternate Configuration Sites

The Contractor may be required to operate sites that differ from those described above through separate Task Orders under this IDIQ Contract. These may include expanded monitoring or reduced cost sites.
