BACKGROUND INFORMATION
The Central Landfill property is situated between Shun Pike and Central Pike in Johnston, Rhode Island. The site is located in a rural area of largely undeveloped or residential property. The approximate location of the USTs are depicted on Figure No. 1. as present approximately 700 feet(+) to the southeast of the active landfill in the vicinity of the landfill office building. The precise location of the tanks is unknown, and no evidence of filler pipes or discharge equipment remains. Their suspected location is now partially paved.
Based on discussions with CLF operation personnel, it is GZA's understanding that two inactive USTs are present at the site. Sources indicate that the smaller of the two tanks, approximately 1000 gallon capacity, was used to store gasoline. The larger tank, suspected to be 2000 gallon capacity, was used for the storage of either diesel fuel or fuel oil. The age of the tanks is not known, however sources indicate that they were taken out of service approximately six years ago (1982). It is GZA's under-standing that the tanks have been pumped and cleaned at the time of their removal from service.
During the period from November 30 to December 12, 1987 a GZA geologist observed the excavation efforts required to construct the present sedimentation/retention pond adjacent to the landfill office building. During excavation efforts along the northeastern perimeter of the pond GZA noted a strong petroleum-like odor in the vicinity or the suspected tank locations. To evaluate the nature of the odors GZA collected three soil samples from a depth of approximately 5 feet for laboratory screening. Soil samples were screened for the presence of volatile organic vapors using an HNU photoionization detector (Model PI-101) employing a 10.2 eV lamp. The screening results indicated HNU levels of 4, 125, and 150 parts per million (ppm).
Duplicates of the soil samples were subsequently transported to Rhode Island Analytical Laboratories, Inc. (RIAL) of Warwick, RI for further testing. The additional analysis consisted of EPA Method 602 volatile organic compounds (as indicators of gasoline) and oil and grease (as indicators of diesel fuel or fuel oil) . The results of these analysis, as presented on Table 1, indicate that all soil samples contain oil and grease. Similarly, the
TASK DESCRIPTION
Notification of State and Local Authorities: It is the responsibility of the tank removal contractor to notify all - applicable state and local authorities of the anticipated tank removal, including; the Rhode Island Department of Environmental Management (RIDEM), the Town of Johnston Fire Department, the U.S. Environmental Protection Agency (EPA) and Dig Safe.
Location of the underground storage tanks: The location of the storage tanks will be performed as a joint effort between GZA and H.H. Watson, The approximate location will initially be determined by GZA employing a Metrotech Model 480 metal detector. The suspected locations and depth to the tanks will then be confirmed by H.H, Watson employing an air rotary rock drill.
Waste Removal and Disposal: The tanks will then be exposed by H.H, Watson, and a determination made as to the amount and nature of their contents, if any. Any liquids contained in the tanks will be removed by H,H, Watson by means of a vacuum truck. H,H. Watson will also be responsible for the proper storage, and subsequent disposal of any materials removed from the tanks. Such activities will be conducted in accordance with RIDEM's Rules And Regulations For Hazardous Waste Generation, Transportation, Treatment, Storage And Disposal, as amended. The RISWMC will be designated the generator of hazardous wastes removed from the site for off-site disposal.
Tank Excavation: Tank excavation will be performed by H,H. Watson, Excavated soil will be screened in the field by GZA using an HNU Model PI-101 photoionization detector employing a 10,2 eV probe. Contaminated soil, as defined by representatives of the RIDEM and EPA in conjunction with the RISWMC, shall be segregated from uncontaminated soil and properly contained for subsequent disposal by H.H. Watson. '
/ Tank Removal: The removal, cleaning, inerting and
disposal of the USTs will be performed by H.H. Watson.
Collection of Soil Samples: GZA will be responsible for the collection and field screening of soil samples using an HNU. Soil samples will be collected throughout the excavation in triplicate for field screening, laboratory screening (HNU), and additional analysis. Selected soil samples (those indicating elevated HNU readings) will be transported to RIAL for
confirmatory analysis consisting of EPA Methods 601 and 602, and oil and grease. Analytical testing will be performed in accordance with Test Methods for Evaluating Solid Waste, Physical/ Chemical Methods, US EPA, SW-846, September 1986, Third Edition.
Additional Soil Excavation and Removal of Liguids: Based on GZA's field screening of soil samples, a determination may be made in the field by the RIDEM and EPA in conjunction with representatives of RISWMC to continue soil excavation in order to remove material judged to be contaminated. Again, the excavation, containment, and disposal of contaminated soil will be the responsibility of H.H. Watson.
Health and Safety: GZA personnel will perform their activities in accordance with the guidelines set forth in the project Health and Safety Plan attached as Appendix A. This plan has been prepared for the health and safety of GZA personnel. GZA assumes no responsibility for the health and safety of other personnel working on the site. However, GZA will inform individuals in the work zone of perceived unsafe conditions,
Backfilling; It is the responsibility of H.H. Watson to backfill the tank excavation and leave the working area in suitable condition. Excavated soils judged not to be contaminated may be replaced, additional soil necessary to bring the area to grade will be the responsibility of H.H. Watson.

SITE HAZARDS
CHEMICAL HAZARDS:
GZA has been involved in a number of extensive environmental investigations at the Central landfill Site, many of which involved the collection and analysis of groundwater and soil samples. Based on our knowledge of site conditions, we do not anticipate that contaminated soils and/ or groundwater will represent significant (acute) hazards to site workers. Notwithstanding, as identified below, a variety of chemical constituents are suspected to be present in soils in the direct vicinity of the USTs, GZA has relied on this information in selection of "action levels". It is our opinion that such values realistically represent worst case conditions.
Source Potential Chemical Contamination:
* Contaminated soils
* Contaminated groundwater
Representative Chemicals TLV/ IDLH (ppm)
Benzene* 10/ 2000
Ethylbenzene* 100/ 2000
Toluene* 200/ 2000
Xylenes* 100/ 10,000
* indicates compound was present in soils collected in the vicinity of the tanks.
Chemical Characteristics of Consideration:
Note that the acute health considerations described below are based on direct contact with pure substances. The information presented below is to provide information to workers regarding repeated contact. Chemical characteristic information is presented for only those compounds detected in soils in the vicinity of the USTs,
Compound Characteristic Odor Threshold (ppm)
Toluene eye/skin/resp,tract irritation 100
Benzene eye/skin/resp.tract irritation 5
Ethylbenzene eye/mucous mem. irrit., headaches 2 5
Xylene(s) eye/skin/resp.tract irritation 4
Major Routes of Exposure: Organic solvents are generally quite volatile, therefore, inhalation is the primary route of entry into the body. Many organic solvents are also readily absorbed through the skin.
Symptoms of Exposure/Potential Health Effects; The symptoms of . exposure to organic solvents include dizziness, loss of coordination, confusion, headache, nausea, abdominal pain, and general malaise. Symptoms may be very mild, or severe, depending on degree of chemical toxicity and magnitude of exposure. Severe over-exposure can cause loss of consciousness (fainting), and may result in potentially serious health effects.
Individual chemical compounds may differ from one another in their toxicological properties, but as a group, organic solvents are associated with the following health effects; Skin contact can result in drying, cracking, and irritation of the skin. Short-term heavy exposure, or repeated low-level exposures, may result in liver, kidney, neurological, circulatory, respiratory, or reproductive damage. In addition, certain organic solvents are classified as mutagens, teratogens, and/or carcinogens,
PHYSICAL HAZARDS:
If digging test pits, the additional hazards of a swinging backhoe bucket, collapse of excavation, etc, exists.
NOISE HAZARDS:
The noise associated with operation of heavy equipment can cause permanent, irreversible hearing loss. Proper hearing protection (ear muffs or plugs) should be worn when working near a source of loud noise,
FIRE HAZARDS:
Because of the flammable nature of materials present in USTs and surrounding soils, fire/explosions hazards may exist. Similarly, based on GZA's prior subsurface exploration efforts it has been our experience that high levels of landfill gas (methane) are released during such activities. Such conditions pose both a fire and a oxygen deficiency potential. To evaluate such conditions, tank excavations will be monitored using a Combustible Gas/ Oxygen Meter (LEL/O2), As a precaution GZA employees and their subcontractors will maintain the following safety precautions;
A. Smoking will be prohibited in the vicinity of the excavation.
B. No employee will enter an open test pit of tank,
C. The "action levels" described below will be strictly enforced.
D. Should the prescribed "action levels" be reached GZA employees will halt work efforts and immediately notify the Project Manager or Health & Safety Officer, Decisions regarding the appropriate remedies to stop or control conditions will be made by these individuals.
SITE PERSONNEL REQUIREMENTS
MEDICAL MONITORING:
GZA personnel must be participants in GZA's medical monitoring program, and must have had their most recent exam within the previous 12 months. The exam must have indicated no medical restrictions that would inhibit personnel from performing the required work tasks,
HEALTH & SAFETY TRAINING: Site personnel must have had at least 4 0 hours of relevant health and safety training and/or equivalent experience which included coverage of hazard recognition, use of site monitoring instruments, use of personal protective equipment, etc.

When oxygen deficiency and/ or elevated LEL readings are measured discontinue work at that location and consult with Project Manager and/or health & safety rep. regarding necessary precautions.
t 0 to 25% LEL near work zone....work with caution
t > 25% LEL near soils discontinue work at that location and notify Project Manager and/or health & safety rep.
PERSONNEL &'EQUIPMENT DECONTAMINATION:
* Remove gross contamination from tools, respirator, monitoring equipment, boots, etc. prior to leaving the work-site, using water, paper towels, handi-wipes, etc,
* Either completely decontaminate soiled equipment at the work-site using detergent & water (if possible), or wrap equipment in plastic bag for transport until complete decontamination is possible,
* Dispose of contaminated gloves, Tyvek suits, used cartridges, paper towels, etc, by placing in a plastic bag and discarding in regular trash.
* Wash hands & face thoroughly with soap and water before lunch or coffee breaks, and as soon as practicable after finishing work for the day.
EMERGENCY PROCEDURES:
PERSONAL INJURY—Administer appropriate first aid. If injury is serious, transport the victim to the nearest hospital. If possible, notify hospital in advance of incoming patient and nature of injury. If there is a question about whether it is safe to move the victim, DO NOT move the victim—instead, make him/her as comfortable as possible, and . summon emergency assistance.
CHEMICAL EXPOSURE—If site personnel show signs of inhalation exposure, retreat to fresh air for recovery. If symptoms are serious, such as nausea or fainting, bring the .victim to the nearest hospital for observation, and discontinue work at that location and consult with H & S representative.
In case of skin or eye irritation due to chemical contact, wash
affected skin with soap and water, or flush eyes with generous amounts of water. If irritation is serious, seek medical attention.
FIRE—If fire can be easily contained and extinguished, do so with fire extinguisher. If explosion -risk is present, do not attempt to extinguish—evacuate all personnel to a safe area and call the fire department.
IMPORTANT NOTE: IF SITE OBSERVATIONS, SAMPLING RESULTS, OR ANY OTHER INFORMATION INDICATES THE PRESENCE OF CHEMICAL CONTAMINANTS OTHER THAN HALOGENATED OR NON-HALOGENATED ORGANIC SOLVENTS (OR FUELS), THIS HEALTH & SAFETY PLAN BECOMES VOID, AND A NEW PLAN MUST BE PREPARED AND APPROVED!
