CERCLA directed the U.S. Environmental Protection Agency (EPA) to identify the sites that pose the greatest relative danger to human health or the environment. In response, EPA developed a site assessment process to evaluate and screen sites within the Superfund program. The main components of the site assessment process (see figure on next page) are: CERCLIS. The CERCLA Information System (CERCLIS) is EPA's data base to record and track activities at all sites discovered. EPA learns of sites in many ways, including federal programs, state and local programs, and citizen notifications. Preliminary Assessment. EPA or the state conducts a preliminary assessment (PA) at every site entered into CERCLIS. The PA a relatively low cost review of available information determines if the site warrants further CERCLA action. After the PA, EPA decides either to send the site forward in the assessment process or to classify the site as NFRAP (no further remedial action planned under CERCLA). Site Inspection. The site inspection (SI) involves more detailed data collection, including environmental sampling. Based on the SI, EPA either recommends scoring the site with the Hazard Ranking System (MRS) or classifies the site as NFRAP. Hazard Ranking System. The MRS uses information gathered during the PA and SI to screen and identify sites consistently for the National Priorities List (NPL). The MRS results in a numerical score that is used to set priorities for more detailed site investigation. In general, sites scoring 28.50 and above are added to the NPL, and sites scoring below 28.50 are classified as NFRAP. National Priorities List. The NPL identifies sites that warrant more detailed evaluation and possible remedial response. Adding sites to the NPL is a rulemaking processsites are proposed for the NPL in the Federal Register, the proposal is subject to public comment, and those sites with MRS scores that remain above 28.50 after public comment become final NPL sites. This report is one in a series providing information on the nature of the sites being evaluated by the Superfund site assessment program. It is intended to provide a "snapshot" of sites in Region 9 on the NPL as of February 1991. Separate reports are available for the other nine EPA Regions and for the nation as a whole. Other reports in this series cover the CERCLIS characterization project, which provides representative information on the types of sites in the CERCLIS inventory. National and Regional CERCLIS characterization reports also are available. 1.1 PROJECT OBJECTIVES In 1989, EPA undertook a project to characterize sites on the NPL. The project's main objectives were to: increase understanding of the characteristics of NPL sites; develop a centralized repository for NPL site information; and summarize the types of sites the Superfund program is addressing. ------- SUPERFUND PROCESS Site Assessment Phase NFRAP (Information Provided to States & Other Regulatory Authorities) Removal Actions May Occur at Any Stage Remedial Phase Removal Actions May Occur at Any Stage ------- Because the characterization is based on information collected during the screening stages of the Superfund process, it does not represent a comprehensive characterization of NPL sites. The site assessment program is a screening program hundreds of sites pass through the PA and SI stages annually. EPA's understanding of sites may change after more detailed investigations are conducted during the remedial stage of the Superfund process. The figure on the previous page illustrates the position of the site assessment stage in the context of the overall Superfund process. This report provides a summary of the characteristics of NPL sites in Region 9 as they are understood at the time of listing. 1.2 GENERAL METHODOLOGY The NPL characterization project evaluated 1218 sites the 1189 sites on the NPL as of February 1991 plus 29 sites that have been deleted from the NPL because all appropriate response actions have been taken. (Four sites deleted early in NPL history were not included.) The 79 sites that were proposed for the NPL but subsequently dropped from further consideration were not included. The proposed sites were dropped because of policy issues or because their MRS scores fell below 28.50 (the cutoff point for listing) after public comment. The table below indicates the number of sites in each EPA Region that were reviewed. Of the 105 sites located in Region 9, four had been deleted as of February 1991. EPA published the original MRS on July 16, 1982 (47 FR 31180). The Superfund Amendments and Reauthorization Act of 1986 (SARA) required EPA to revise the MRS to assess more accurately the relative risk posed by waste sites. The revised MRS was published on December 14, 1990 (55 FR 51532). The NPL characterization project evaluated the complete set of sites that were listed based on the original MRS (with the exception of four deleted sites as noted above). Sites listed on the basis of the revised HRS were not evaluated. Data for the NPL characterization project were collected in two stages. First, the final HRS package for each site (filed at the EPA Headquarters Superfund Docket) was reviewed. Then, any data gaps were filled by reviewing the Regional site files. 1.3 RESULTS The results of this report are presented in chart form in Chapters 3 through 9. These charts include information about: site description, owner/generator, regulatory and response history, HRS scoring, waste description, site environment, and water use. The box at the bottom of the next page provides information to assist the reader in interpreting the charts. Listed below are notable findings of the NPL characterization project for Region 9. Over a quarter of NPL sites in Region 9 are located in rural areas; approximately 16% are located in urban areas (Chart 1). Over a third of Region 9 NPL sites manage(d) wastes in industrial landfills; NUMBER OF SITES REVIEWED FOR NPL CHARACTERIZATION PROJECT Region Number of Sites 1 84 2 204 3 160 4 158 5 265 6 71 7 59 8 I^J 10 43 | 105 | 69 Total 1218 ------- over a third manage(d) wastes in surface impoundments (Chart 4). Nearly half of Region 9 NPL sites are owned by private industry; about a quarter are owned by the federal government (Chart 7). Approximately 70% of NPL sites in Region 9 are active facilities (Chart 9). Nearly one-half of NPL sites in Region 9 contain wastes generated by manufacturing industries (Chart 10). Over 60% of Region 9 NPL sites were identified through state and local programs (Chart 17). Over 80% of NPL sites in Region 9 have released hazardous substances to ground water; over 20% have released hazardous substances to surface water (Chart 23). Nearly a quarter of Region 9 NPL sites have a sensitive environment within 3 miles (Chart 33). Over 90% of Region 9 NPL sites have operable wells within 1 mile (Chart 39). 1.4 ORGANIZATION OF DOCUMENT This document consists of nine chapters and three appendices. Chapter 2 provides more detailed information on data collection activities and includes the data collection form and instructions. Chapters 3 through 9 present the results in chart form. Appendix A lists all of the individual responses for the "other" response category, which are not displayed separately on the charts in Chapters 3 through 9. Appendix B lists the sites reviewed, and Appendix C contains a map that shows the locations of these sites. INFORMATION ABOUT THE CHARTS Data were generated from a review of NPL site files in 1989. Except where noted, charts depict information for 105 sites reviewed in Region 9 101 that were on the NPL as of February 1991, and four that had been deleted because all appropriate response actions have been taken. Efforts were made to characterize site conditions/surroundings as they existed at the time of the HRS score. The HRS scoring package and associated references served as the primary information source. Percentages on some charts do not total exactly 100 percent due to rounding. Percentages on some bar charts total to greater than 100 percent because multiple responses to certain questions were possible. ------- CHAPTER 2: DATA COLLECTION METHODS Before the NPL characterization project, information on Region 9 NPL sites was available in individual site files at EPA Headquarters and the Regional office. The project compiled and centralized site-specific information on the characteristics of these NPL sites. This chapter describes the data collection activities. The table on the next page summarizes the process used to collect data. 2.1 DATA COLLECTION PROCEDURES After developing the overall approach to the NPL characterization project, EPA prepared a data collection form. A copy of this form is provided in Section 2.4. The design of the form was based in part on the form used for the CERCLIS characterization project, an earlier companion project. A few new questions were added and some existing questions were modified to capture information more pertinent to a study of NPL sites. An instruction manual (see Section 2.5) was developed to promote consistency and accuracy in data collection. The data collection form and instruction manual should be consulted for a full explanation of the definitions used in the report. Data collection procedures were tested on Region 10 sites. As a result, a few modifications were made to the data collection form. The modified form, as shown in Section 2.4, was used in Region 9 as well as the other eight Regions. stage of the data collection process by reviewing MRS scoring packages at the Headquarters Superfund Docket. The second stage involved filling in data gaps at the Region 9 office. Information reviewed included HRS scoring package reference documents such as SI reports, PA reports, maps, and records of telephone contacts. After data for all Regions were collected and verified, the project team compiled one national data base. The data base was then analyzed to calculate response frequencies for each of the data fields. 2.3 QUALITY ASSURANCE/ QUALITY CONTROL The first level of quality assurance/quality control (QA/QC), conducted at the Regional office, involved comparing the information collected at EPA Headquarters with the information available in the Region and, where necessary, resolving differences. After information on the data collection forms was entered into the data base, the data base was reviewed to ensure that the information had been properly transferred. A second level QA/QC involved reviewing the data base for completeness, consistency, and accuracy. In addition, the graphics produced for this and all other reports were checked for consistency with the data base. 2.2 SOURCE OF DATA Most of the questions on the data collection form could be answered in the first ------- PROCESS USED TO COLLECT DATA TASK Headquarters Docket Review Regional Visit: File Review Regional Visit: First Level QA/QC Data Entry/ Verification Second Level QA/QC Statistical Analysis DESCRIPTION Review HRS scoring packages for every NPL site.

This data base will be used to perform a statistical characterization of waste sites on the NPL All proposed and final NPL sites will be reviewed for data compilation, including former final sites deleted from the NPL because the Agency determined that no further response was necessary. The NPL Statistics Data Collection Form is designed so that all required information can be obtained by a review of the MRS package and supporting materials contained in Regional EPA NPL files. It is important that all questions on the form be answered even if the appropriate answer is "unknown." Estimates based on best professional judgment are allowed, but hard data are preferred. In some cases, the response "other!1 can be used along with a brief narrative if the available choices do not adequately describe the site or situation. Additional information to support the use of this category should be included in the "Comments" section at the end of the form. RESPONDENTS ARE ENCOURAGED TO USE THE "OTHER" CATEGORY AS MUCH AS NEEDED. The Data Collection Form contains six sections which are listed below. The name of the file reviewer should be written on the front in the top margin. The form should be completed in dark pencil so that later QA/QC corrections to the form will still result in an easily legible document for data entry purposes. Section 1 - Record Information, which provides basic identification information; Section 2 - Site Description, which describes the ownership, status, and history of the site; Section 3 - Waste Description, which describes the types and quantities of wastes present at the site; Section 4 - Environmental/Demographic Information, which provides information on water supply, population, and environmental damage; Section 5 - Regulatory and Response History, which covers any regulatory activity that occurred prior to CERCLA involvement and includes RCRA status; Section 6 - Comments, which provides space for a brief description of the site, including a list of contaminants and comments on data availability or associated problems with completing the form. Explanations of "other" responses should also be given here. Section 1 - Record Information 1. Site Number: This is the number by which the site will be identified in the data base. It is essential that this number be entered correctly on the form. The Site Number is the seven digit, Regional ID number for that site, usually marked on the 1 This section is a slightly edited version of the actual instruction manual that accompanied the data collection form. 11 ------- HRS scoring package cover page. In the case of some proposed sites, an ID number indicating the Update Number is given and should be used. When entering the Site Number, it is required that the commonly accepted two letter abbreviation for the state's name precede the Regional ID number (or other number) for the site. NOTE: If no identification number is available, use any reasonable means of numbering, but remember to precede the number with the state abbreviation. 2. Site Name: This is the name of the site as identified on the NPL. Copy the complete name of the site in the space provided. Also, enter the location of the site (town/county and state) directly below the site name. Section 2 - Site Description 1. Coordinates: Enter the coordinates, latitude and longitude, of the site in degrees, minutes, seconds, and tenths of seconds. If tenths of a second are not given, enter zero as a default value in the appropriate space. If no coordinates are available at all, leave blank and mark "unknown," while specifying site location (eg., township and range) in the collection form's "Comments" section. Because latitude and longitude provide necessary input for interaction with other data bases, it is particularly important that these values or descriptions be included. 2. Setting: Setting is a qualitative measure of population density near the site. Mark the appropriate box to indicate the character of the area surrounding the site. "Urban" indicates central city areas, "suburban" Indicates sites bordering or surrounding urban areas, and "rural" indicates sites outside suburban areas. Select the one setting that best describes the site. This information may be derived from an accompanying map. Generally, the number of homes and/or industrial buildings indicated on a map may be used to estimate the site setting. Since the character of the area is relative to population density, a site in the center of a city such as Roanoke Rapids, which is located in rural North Carolina, would be classified as "urban." 3. Location Land Use/Site Use: The predominant land uses within approximately 1 mile of the site location should be determined and all appropriate descriptions identified. If the land immediately adjacent to or on site is used for activities associated with large numbers of people, or a sensitive environment which could increase the risk posed by the site, describe the appropriate land/site use in the "other" category. Examples of "others" include: railroad school/college airport harbor/marina sports complex federal/state park wetland Mining, military, or DOE should be checked only if they correspond to actual site use or immediately adjacent site use. Additionally, if the site or area had a predominant historical usage (e.g., railroad yard, landfill, power substation), identify this in the "other" category with the words "past" or "previous." 12 ------- 4. Current Ownership: Check one appropriate box to indicate the type of ownership of the site at the time of the MRS score. For purposes of this data field, operators may be characterized as "owners" if ownership distinctions are not made. For consistency, treat the following situations as detailed below: If ownership/operation is by multiple individuals, businesses, or industries, indicate "other" and state the condition. However, if all owners belong to the same category, it is not necessary to put this under "other;" simply check the appropriate category. When the site is a contaminated ground water plume, as defined by contaminated wells, mark "other" and enter "contaminated ground water plume." 5. Ownership When Contaminated: Check the appropriate box to indicate the type of ownership at the time the site was contaminated. As in item #4, ownership refers to owner and/or operator if a distinction is not made. Procedures for ownership when contaminated are similar to current ownership. 6. Area of Site: Indicate the area of the site, along with the appropriate units. The area of the site includes the "source" of the waste and the area that has come to be contaminated. If the area of the site is reported as a range, use the midpoint of the range. Again, this data field is intended to capture the area of contamination. So, for example, if there is a large facility but only a small area is actually contaminated, only the area of contamination should be entered. If the specific area of contamination is unknown, use the area of the facility, if reasonable (use best professional judgment), and note this in the "Comments" section. For ground water contamination plume sites, area refers to the planar area of the plume. Generally, the area of the site will be given in the narrative that accompanies the MRS scoring package. 7. Site Status: Check the appropriate box to indicate the status of the site at the time of the MRS score. Sites are to be considered "active" if waste treatment, storage, or disposal activities are taking place at the time of the MRS score. These activities do not necessarily have to be those that resulted in the site being considered for the NPL. Sites that have changed ownership or operations are still considered "active" if the new operations possibly involve hazardous materials/wastes. "Inactive" sites are those at which treatment, storage, or disposal activities no longer occur. For consistency, address the following conditions as described below: Check "active" for those sites that currently have both active and inactive treatment, storage, or disposal units. Consider contaminated ground water plume sites "active." 8. Years of Operation: Enter the beginning and ending years of waste treatment, storage, and/or disposal at the site. If the site is "active," enter the HRS date for the ending date. Check "unknown" if the beginning or ending years of operation are not known. For consistency: if waste activities occurred during only one year (e.g., one-time event, accidental spill), the years of operation of the facility should be 13 ------- entered, and noted in the "Comments" section. If the site is a contaminated ground water plume, use a default value of 0001 and 0001 for the beginning and ending years. 9. Industry Responsible for Generating Material: Check all appropriate boxes that indicate industries responsible for generating the wastes that occur at the site. This refers to the industry responsible for the waste, not the original product. For example, if a hardware store has drums of pesticides which leak, the industry responsible is "retail" and not "manufacturing." It is important to try to categorize the industry into one of the types listed for statistical analysis. If these listed industry types aren't applicable, check "other." Further information may be provided under the "Comments" section. For consistency among respondents, please note the following guidelines: If the site is a military facility, only "military" should be checked. Only check the "unknown" category if little or no information is available on the responsible industry or industries. "Food and kindred products" refers to food packaging/processing industries (e.g., canneries, bottlers) and the manufacturing of home goods such as toothpaste, shampoo, and cosmetics. "Chemicals and allied products" also includes paint manufacturing. Mark "electroplating" for any type of metal coating or metal finishing industry, unless the industry employs another type of coating as the predominant activity (e.g., paint, plastic). For the majority of cases, the "other" category should be used if a specific general or subcategory of another type is not obvious. Examples of "other" categories include: combination industrial/ correctional facility municipal landfill distributor (gas, oil) industrial landfill salvage yard waste storage/transfer aircraft-related facility service POTW radium processing 10. Site Activities/Waste Deposition: Check all appropriate boxes to indicate what types of treatment, storage, or disposal operations occur/occurred at the site. If the available categories are not sufficient to characterize the activities occurring at the site, check "other" and supply a description. For consistency among respondents, please note the following guidelines: "Surface impoundments" should be restricted to primarily liquid containment. "Waste piles" may be covered or uncovered. 14 ------- "Industrial dump" refers to an illegal waste pile of industrial trash, chemicals, debris, etc. "Illegal dumping" ("out the back door") indicates situations where wastes are intentionally disposed of in undesignated disposal areas (e.g., dumping liquids and sludges onto the ground). "Episodic open dump" is a site at which third parties illegally dump wastes, often times without the knowledge or approval of the site owner/operator. Note that "episodic open dump" may be an appropriate category even for a permitted facility if, for example, area residents or industries dispose of wastes at the site without authorization. Tanks above ground" should be checked when the type of tank is not indicated, unless the site is a gasoline retail station. "Other sludge activity" refers to any sludge disposal action which cannot adequately be described by the other categories. "Discharge to sewer" should be checked when wastes have been intentionally discharged to either a sewer or a surface water body. This category does not refer to wastes entering sewers or surface water as a result of secondary run- off. Permitted discharges should be noted in this category as well as in the "Regulatory Activities" section. "Airborne release" should be checked when incinerators, boilers, fire or burn pits, excessive dust, etc., are present at the site. "Drum/container storage" refers to intentional storage in specific areas. "Spills" are accidental in nature, mostly one time only occurrences. Leaking drums do not qualify as spills. Once again, try to categorize the activities or check "other" and give a description. Examples of legitimate "others" include: # pesticide applications wash pads septic tanks and leach fields sumps dust suppression dry wells 11. How Identified: Check the appropriate box to indicate how the site was initially identified to the EPA Superfund Program. "Incidental" should be checked if the site was identified as a result of fortuitously driving by it, or by investigating another site. Anonymous complaints are categorized as "citizen complaints." "Other Federal program" should be marked for site identification through programs such as the DOD Installation Restoration Program. Examples of possible "other" categories include Congressional inquiry (e.g., Eckhardt list) and ERRIS listing. 12. Material Deposited By: Indicate the entity responsible for the actual waste deposition. For example, "present owner" would be checked if a private individual 15 ------- authorized the dumping of chemical wastes on his property. However, "third party" would be checked in the same scenario if the property owner had not authorized the dumping. Again, for this category, "owner" refers to owner and/or operator. For consistency, check 'third party" for all contaminated ground water plume sites. 13. Date Discovered: Enter two digits for the month, day, and year that the site was identified to the EPA Superfund Program. For example, June 27, 1982, would be entered as 06/27/82. In the event that the day or month is unknown, use 01 as the default value for each. If the date cannot be determined, check "unknown." 14. Material Source: Indicate whether the waste material was generated on site and/or off site, as appropriate. Recyclers are considered "on-site generators." For consistency, check "off-site generator" for contaminated ground water plume sites. 15. Waste Easily Accessible: Indicate whether or not the waste is easily accessible to the general public. On-site workers should not be considered for this data field. Items to be considered in judging accessibility include complete cover over the waste area or a secure fence around the site. For example, waste material exposed at the surface in a park or playground is easily accessible, while waste exposed at the surface of .a site surrounded by a locked chain-link fence is not easily accessible. For consistency, the waste should be considered not easily accessible for contaminated ground water plume sites. 16. First Proposed: Check the appropriate box identifying in which update the site was first proposed in the Federal Register (this is usually listed under site name on the NPL folder). 17. NPL Status: Check the NPL status of the site as of proposed Update #9, July 1989. The NPL status of sites to be proposed for Update #10 should be marked as proposed. 18. CERCLIS Number: Enter the 12-digit CERCLIS number (usually on the SI form or CERCLIS printout). 19. MRS Score: Enter the MRS site score (Sm) from the MRS scoring package. If the scoring has been amended, use the most recent score. In the "Comments" section, indicate the score for each of the migration pathways. 20. Miscellaneous Descriptive Information: Identify, as appropriate, multiple ownership or emergency action conditions. Examples of "other emergency action" include: well closing fences distribution of bottled water consent decrees Additionally, the presence of lead (Pb) at a site should be noted in the appropriate data field. 16 ------- Section 3 - Waste Description For data fields #1 -3, wastes have been divided into three major groupings based on the physical state of the waste: solid, liquid, and sludge. The physical state of the waste refers to the waste as deposited and is usually identified as such in the MRS package or in the PA or SI. For example, slurries are identified as either liquid or sludge, rarely as solid. The presence of each of these waste states at the site needs to be determined, along with the quantities involved. Each waste state grouping has been further divided into the type of waste deposited. The procedure for completing this section, which should be followed for each waste state, is as follows: 1-3 Solids, Liquids, Sludges: First determine if the particular waste state being evaluated ("solid" will be used here as an example) is/was present at the site. If solid wastes are/were not present, check "none." If solids are/were present, then mark the appropriate waste type. If the subcategories listed are not sufficient to characterize the particular waste stream, check "other." As with the previous sections, the evaluator should use the categories presented if possible, or check "other" and provide a brief description. Some examples of "other" waste streams include: spent fuel biological waste (animal carcasses) drilling muds (sludge) batteries dust construction debris agricultural waste Finally, total the quantities of all waste streams and fill in the amount in the space provided. Remember to mark the appropriate units. NOTE: Identify the specific contaminants found at the site in the upper right hand corner of the "Comments" section. Section 4 - Environmental/Demographic Information 1. Demographics: a. Distance to Nearest Population: If known, provide the distance from the site boundary to the nearest population. Also, indicate the unit of measure that was used. Population includes those persons occupying houses, apartment buildings, schools, and businesses. Use maps, if available, to provide best estimates. If there is an on-site resident population, use 10 feet as a default value. b. Population Within 1 Mile?: If there is a population within 1 mile of the site, check "yes" and enter the number of people within this radius. When the number of individual residences is known, the convention is to multiply by 3.8 individuals/residence and use the product value as a reasonable population estimate. If a reasonable population estimate cannot be determined, check "yes" and leave the number field blank. A map may be used to determine population. If no appropriate information is in the file, check "unknown." 17 ------- c. Population Within 3 Miles?: Follow the same procedures as described above. Again, a map may be useful. If data are available regarding population within 4 miles of the site, indicate this and use the information. If this information is not in the file, mark "unknown." By definition, if there is population within 1 mile of the site, there is also population within 3 miies of the site. 2. Actual Environmental Damage Reported, Potential Population Affected: Indicate whether actual environmental damage has been reported at this site. Note that this does not include potential damage, only documented cases of actual impacts. For example, if the PA report states that leachate was observed entering an adjacent stream or wetland, this can be considered an actual surface water impact, even if sampling results are not available. If 'yes," indicate the type of damage that was reported and estimate the population that could potentially be affected. If the potential population is not known, write "unknown" in the space provided. Please note that, by definition, if an "HRS-observed release" has been scored for a given pathway, then an environmental impact has been reported for that pathway. NOTE: The number for potential population is often provided on the PA or SI form. 3. Observed Releases: Indicate whether an observed release of contaminants has been documented. This information is available in the MRS scoring package. 4. Water Supply Information for a 3-Mile Radius: a. Local Drinking Water Supply Source: Identify whether drinking water supplies are drawn from surface water and/or ground water within 3 miles of the site. If, for example, the local area has a reservoir but some houses within 3 miles still use wells, then check "surface and ground water." If all drinking water sources are outside of the 3-mile radius, this should be noted as "none." b. Total Population Served: If available, provide the number of people served by the water supply system indicated in #4a. Note that this population should reflect the population served by a source within 3 miles of the site; it may be more or less than the total population within 3 miles. For example, if a well located two miles from the site is used to serve the population of a city of 60,000, the entire population of the city should be included even if the city itself is outside of the 3-mile radius. If there is no drinking water population (all sources are outside 3-mile radius), use a default value of 01. c. Drinking Water Supply System Type: Indicate the type of water supply system for the sources identified under #4a. "Municipal" should be indicated for any central water supply system, even if it is operated by a private water company, utility, or individual (e.g., trailer park serviced by one privately owned well). 18 ------- d. Ground Water Data: Other Local Ground Water Uses: Check all appropriate boxes for predominant uses of ground water other than drinking water supply. Monitoring wells should not be considered. Some examples of "other" uses include commercial and dust control. Wells Within 1 Mile?: If there are operable wells within 1 mile of the site, check "yes" and indicate the total number of wells used for any purpose, excluding monitoring wells. Wells Within 3 Miles?: If there are operable wells within 3 miles of the site, check "yes" and indicate the total number of wells used for any purpose, excluding monitoring wells. Distance to Nearest Well: Provide the distance from the site boundary to the nearest operable well, excluding monitoring wells. Indicate what unit of measure was used. If the well is located on site, use 10 feet as a default value. Note that by HRS definitions, the site boundary can be extended to the farthest point of documented contamination attributable to the site. Depth to the Uppermost Used Aquifer: Provide the depth from the ground surface to the uppermost aquifer that is or may be used. If the uppermost aquifer is no longer used because of contamination attributable to the site, the depth to this aquifer should be entered. Always indicate the unit of measure used. If a range of depth is given, use the midpoint value for the data field. Use a default value of 1 foot if waste was directly deposited below the water level of the uppermost used aquifer. NOTE: "Depth to the Uppermost Used Aquifer" is often provided in the HRS scoring package. e. Surface Water Data: Other Local Surface Water Uses: Mark all appropriate boxes for uses of surface water, other than drinking water supply, within 3 miles. Surface Water Adjacent to/Draining Site: Identify all types of surface water adjacent to or draining the site that could potentially be affected by overland runoff from the site. Use professional judgment and HRS definitions as necessary. Distance to Nearest Downstream Intake: Provide the distance to the nearest downstream intake in feet or miles, if known. 5. Ecological Information: Is Site In Or Near Sensitive Environment?: Sensitive environments are defined as estuaries, 100 year floodplains, critical habitats (Federally designated only) and some coastal areas. If the site is in or near one of these environments, indicate the 19 ------- type of sensitive environment and whether the site is "in" or "near" the environment. "Near" is considered to be within a 3-mile radius. 6. Pathways of Concern: Check all pathways that received a score greater than zero in the MRS scoring package. When reviewing the MRS scoring package, please note the actual score for each pathway in the "Comments" section. Section 5 - Regulatory and Response History 1. Regulatory Activities Prior to Preliminary Assessment: Indicate any regulatory activities that occurred at the site prior to the PA. Examples of these activities could include RCRA notification or inspections, NPDES permits and/or exceedences, State health department inspections of landfills and/or DOD Installation Restoration Program activities ("other Federal program" category). 2. RCRA Status: Indicate the appropriate RCRA category. If the site is not a RCRA site, check "not applicable." Ground water contamination plume sites are to be included in the "not applicable" category. Section 6 - Comments This section is not an optional segment of the data collection form. It must be completed, at a minimum, with a brief narrative description of site conditions, including any discussion or clarification of the information presented elsewhere on the form. In addition, each form must be quality control checked for completeness, and initialed by another evaluator in the lower right corner of page 4. The "Comments" section is a crucial component of the data collection form; verbosity is encouraged. 20 ------- CHAPTER 3: SITE DESCRIPTION Chart 1: Site Setting Chart 2: Area of Site Chart 3: Predominant Land Uses in Site Vicinity Chart 4: Treatment, Storage, or Disposal Activities Occurring at Site Chart 5: Waste Easily Accessible to Public Chart 6: Distance to Nearest Population 21 ------- REGION 9 Site Setting LEGEND: p>v| 1 Urban 2 Suburban 3 Rural | | 4 Not Specified Note: This figure depicts information collected on the NPL Statistics Data Collection Form in the Site Description Section, Question 2, Setting.
