NAME COMPANY DATE I I I I I I I I I I I • I I I I I I I HEAL TH AND SAFETY PLAN North Carolina State University Lot 86 Site Raleigh, North Carolina SITE HISTORY The NCSU Lot 86 site (Figure I) is located on the west side of Raleigh, North Carolina, near Carter-Finley Stadium, approximately 100 feet south of the southern right-of-way of Wade Avenue Extension. Wade Avenue Extension connects with Interstate 40 (I-40), which is a heavily traveled thoroughfare carrying commuter traffic between Raleigh and Research Triangle Park, as well as interstate traffic. The 1.5-acre site is located in Wake County; furthermore, the site is located on and surrounded by state-owned property. A large grass-covered open area, west of the site and north of Carter-Finley Stadium, is used for parking during stadium events. The dirt road leading into this area from Old Trinity Road is used as a jogging path by NCSU students and area residents. Trees along the fence, north of the site, screen the view from Wade Avenue Extension. A pine forest borders the site to the east. The nearest water supply well is located approximately 2,000 feet southeast of the site, at Medlin residence (Figure 2). NCSU selected Lot 86 of Farm Unit No. I in 1969 as a burial site for hazardous chemical waste and low-level radioactive waste generated in the University's educational and research laboratories. The site was divided into two separate areas as shown on Figure 3; the western half to receive hazardous chemical waste, and the eastern half to receive low-level radioactive waste. Burial of waste was discontinued in November 1980 to comply with regulations promulgated under the Resource Conversation and Recovery Act (RCRA). The site was placed on the National Priority List (NPL) in October 1984, based on an inspection completed earlier in June. The USEPA and North Carolina OHS (Division of Health Services), Solid and Hazardous Waste Branch, completed hazard ranking score sheets for the site and determined the degree of contamination to warrant inclusion on the NPL. The types of chemicals reported to have been buried at the site include solvents, pesticides, inorganics, acids, and bases. The chemical wastes were placed in trenches located in the northwest portion of the site. The trenches were approximately 10 feet deep and 50 to 150 feet long (Figure 4). After filling, about 2 feet of soil, which was excavated during trench construction, was used as cover material.

The University estimates that approximately 22 trenches totalling less than 2,000 linear feet were used. Although some of the liquid chemicals disposed of during the initial site operations were poured into the trenches, both liquid and solid chemicals were generally buried in metal, glass, or plastic containers. NCSU reported on the CERCLA of 1980, Section I03(c) Hazardous Waste Notification form filed on June 8, 1981, that it had disposed of 300,000 cubic feet or about 11,000 cubic yards of waste at the site. NCSU maintains that this quantity includes contaminated soil and water as well as waste material. According to available information, radiological wastes were buried in the eastern portion of the site in trenches approximately 6 feet deep with 4 feet of cover material. Records concern- ing waste disposal in this area are maintained by the NCSU Radiation Protection Office. Most of the waste is in solid form, primarily animal carcasses. These range in size from rats to whole sheep. The carcasses were frozen when buried and were not containerized. Radionuclide present in the waste include tritium, carbon-14, iron-59, phosphorus-30, and phosphorus-32. Groundwater survey results for the LLRW area are shown on Table I, with quantities of buried radioactive material on Table 2. This Health and Safety Plan addresses the activities associated with Remedial Investigation Activities and Treatability Study tasks (if needed) for the chemical and LLRW materials, and groundwater at the site. These activities include soil boring construction and sampling to define the nature and extent of soil contamination, and monitor well installation and sampling to determine the nature and extent of groundwater contamination associated with past site activities.

Adverse weather conditions, sunburn, and heat stress are also potential hazards which must be monitored. The potential chemical and physical hazards are described below. CHEMICAL CONTAMINATION Previous investigations and laboratory analysis for the soil on the site have indicated the presence of the following list of chemicals (Table 3). Table 4 presents exposure limits and additional contaminant information for the key chemicals which may be present at the site. Table 2 shows buried quantities with regard to radionuclides, and Table 5 represents peak concentra- tion values for key chemicals known to have been buried on-site. It is important to note, however, past investigations have not shown radiation levels to be above that of normal back- ground levels. PHYSICAL HAZARDS A number of site specific physical hazards are present at the NCSU Lot 86 site. These hazards are a function of the nature and condition of the site as well as a consequence of the work being performed. The inherent physical hazards include uneven terrain, holes, ditches and native North Carolina plants, animals and insects. Personnel should be aware of these hazards and perform a site walk-through to identify the presence of these hazards. Soil sampling and monitor well installation will be accomplished with the use of a drill rig. Working with and around heavy equipment requires wearing a hard hat and steel-toed boots. Additionally, dust generation during these activities may require eye protection. Care should be taken to identify the presence of underground utilities or tanks and overhead power lines. Noise levels associated with heavy equipment operation may result in permanent hearing loss. Hearing protection will be required for workers in the immediate vicinity of operating drilling equipment. Weather conditions will be closely monitored and all site work will be suspended during thunderstorms, heavy rains, fog, dust storms, hail, hurricanes, and darkness. Sunburn is a physical hazard to site personnel when working outdoors on sunny days for extended periods of time. Excessive exposure to sunlight is associated with the development of skin cancer and BROWN AND CALDWELL 13 H«lltl, tlM SafdJ Pm · No.,,,.J,,w 1992 ' I I I f I I I I I I I I I I' I I I I Table 3 Representative List of Chemicals Included in Waste Burials Aliphatic Alcohols 1-butanol 2-chloroethanol ethanol dihydroxypropane ethylene glycol isopropanol (propyl alcohol) methanol 2-methyl-1-propanol (propyl alcohol) pentanol 2-pentanol propanol (propyl alcohol) 2-propanol (propyl alcohol) Miscellaneous Solvents ethylbe02:ene acetonitrile benzene cyclobexane 1,4-dioxane ether ethyl acetate ethyl ether heptane hexane iso-octane (octane) nilrobenzene pentane pyridine tctraliydrofuran (THF) toluene p-xylene lnorganics aluminum antimony arsenic boron bromine (bromide) cadmium chloride (chlorine) cobalt copper chromium cyanide fluoride Chemicals Inorganics iodine (iodide) iron lead lithium (hydride) magnesium (oxide) manganese mercury molybdenum nickel phosphorus potassium selenium silver sodium strontium sulfur thallium tin titanium zinc Ketones acetone 2-butanone methyl ethyl ketone 4-methyl 2-pentanone 2-pentanone Aldehydes acetaldehyde benzaldehyde formaldehyde Bases potassium hydroxide sodium hydroxide Oxidants benzoyl peroxide hydrogen peroxide potassium permanganate I I I I I I ' I I I I I ' I I ' I Table 3 Representative List of Chemicals Included in Waste Burials (continued) Miscellaneous Organics acenaplhene acrolein acrylonitrile 2-chloroethyl ether di-n-butylphthalate 2-methylbutane 4-methylpent-1-ene nitromethane nitrotoluene styrene p-toluidine trioxymethylene diethyl ether Acids acetic acid benzoic acid boric acid chloroacetic acid chromic acid 2-5-dinitrobenroic acid formic acid hydrochloric acid hydrofluoric acid mercaptoacetic acid mercaptoproprionic acid nitric acid osmic acid perchloric acid phosphoric acid picric acid proprionic acid succinic acid sulfuric acid thioacetic acid thioproprionic acid tribromoacetic acid trichloroacetic acid trifluoroacetic acid Phenols p-chlorophenol 2,4-dinitrophenol p-nitrophenol phenol phenolphthalein Chemicals Pesticides/Herbicides/Fungicides atrazioe carbofuran 2,4-D ODE DDT endrin ethylene dibromide malathion methoxychlor parathion sevin toxaphene Amines bisacrylamide aniline N-butylamine dibutylamine diethylamine N,N-dimethyl formamide (DMF) diphenylamine N,N-diphenyl-p-phenylene-diamine dipropylamine ethylenediamine N-propylamine tetraethylene diamine tributylamine triethylamine trimethylamine Halogenated Hydrocarbons bromobenzene bromoethane carbon telracbloride chloroben:rene 2-chloro-2-methylpropane chlorofOfUI 1,2-dibromoethane 1,2-dichloroethane dichloroethane 2,4-dinitrochlorobenzene ethylene bromide methylene chloride perchloroethylene I I I I I I I ,, I ' Table 3 Representative List of Chemicals Included in Waste Burials (continued) Halogenated Hydrocarbons tetrachloroethane tetrachloroethylene trichlorohen:rene trichloroethylene dichloromethane-1,2-dichloropropane 1,1,1-trichloroethane (methyl chlorofonn) Source: ESE, 1987.

HEAT STRESS Heat stress is a major site hazard when field activities are performed on warm, sunny days, and is accentuated when chemical protective clothing is worn. Heat stress prevention measures and monitoring will be implemented if site temperatures are above 70 degrees Fahrenheit (F). Precautions to prevent heat stress will include work/rest cycles so that rest periods are taken before excessive fatigue occurs, and regular intake of water to replace that lost from sweating. Work/rest cycles will be based on monitoring the heart rate (pulse) of each individual worker. Rest breaks will be long enough to reduce the heart rate (HR) below levels calculated according to the following method: I. The worker will initially determine their resting HR prior to starting work activities. 2. At the start of the first rest period, the worker will determine their HR. This initial HR should not exceed the individual's age-adjusted maximum HR, which equals ((0.7)(220 -age in years)]. At I minute into the rest period, the recovery HR will be determined. The recovery HR should not exceed 110 beats per minute. 3. If the initial HR exceeds the age-adjusted maximum HR, or the I-minute recovery HR is greater than 110 beats per minute, then the next work period will be decreased by l 0 minutes. Temperature monitoring will also be conducted at the end of each work period with a clinical oral thermometer (3 minutes under the tongue). Work periods between rest breaks will be modified by the following schedule: I. If oral temperature exceeds 99.6 degrees F (37.6 degrees C), shorten the next work cycle by one-third without changing the rest period. 2. If oral temperature exceeds 99.6 degrees F (37.6 degrees C) at the beginning of the next rest cycle, shorten the following work cycle by one-third. 3. A worker whose oral temperature exceeds 100.6 degrees F (38. l degrees C) will not be allowed to work in semipermeable or impermeable protective garments. Heat stress due to water loss can be prevented. To prevent dehydration, water intake must approximate sweat loss. Water intake guidelines are as follows: I. The sense of thirst is not an adequate regulator of water replacement needs during heat exposure. Therefore, water must be replaced at prescribed intervals. a. Before work begins, drink two 8-ounce glasses of water. BROWN AND CALDWELL 21 H-,J, 41M s.fot, Pia · N_,_,.. 1991 I I I I ·1: ,. 1· I ,, f ,, ,t ,, 1· ,f I ,Ii . ,, b. During each rest period, drink at least two 8-ounce glasses of water. 2. Plain water, served cool, is excellent An adequate supply of potable water and drinking cups will be readily available, in a support vehicle, to provide water during rest periods. 3. Adding salt to water is not recommended. However, other fluids, in addition to water, could include dilute fruit juices and electrolyte replacement drinks diluted 3: I with water. Do not use salt tablets! An initial work/rest cycle of I hour work and 15 minutes rest is recommended for protec- tion of staff when the heat stress hazard is high. The recommended cycle will be adjusted up or down based upon worker monitoring, environmental conditions, and the judgment of the SSO. If at any time field team members recognize the signs or symptoms of heat stress prior to a scheduled rest period, they will notify the SSO immediately in order that a rest period can be called. Heat stress, if not prevented, results in heat stress illnesses. Two critical illnesses, if not recognized and treated immediately, can become life-threatening. These are heat exhaustion and heat stroke. Heat exhaustion will result if the prevention measures described above are not implemented. Ignoring the signs and symptoms of heat exhaustion will lead to the development of heat stroke. Heat stroke is an immediate, life-threatening condition that results because the body's heat regulating mechanisms shut down, and the body cannot cool itself sufficiently. As heat is excessively stored in the body, brain damage can result causing permanent disability or death. Heat Exhaustion: The signs and symptoms of heat exhaustion are headache; dizziness; nausea; weakness; fainting; profuse sweating; loss of appetite; approximately normal body temperature; dilated pupils; weak and rapid pulse; shallow and rapid breathing; possible cramps in abdomen and extremities; possible vomiting, difficulty walking; cool and sweaty skin to the touch: pale to a~hen gray coloring. First aid for heat exhaustion is as follows: I. Immediately remove victim to the support area, or if you are the victim, proceed to the support area. 2. Decontaminate, if practical, before entering support area. 3. Start cooling, but be careful not to cause a chill ( i.e., rest in shade and apply wet towel to forehead; open up and/or remove clothing as much as practical, especially chemical-resistant clothing). 4. Drink cool water slowly, but only if conscious and not in shock . BROWN AND CALDWELL 22 H.,JJJ, oltd SafdJ Plait • N~ 1991 I I ,, II I Ii I\ ,-,, n It 01 If· ft' I m ,ti/ u cl 5. 6. If vomiting, and/or the signs and symptoms are not lessening within an hour, call for emergency help and/or transport the victim to emergency room. It is likely that a heat exhaustion victim will be unable to work for the remainder of the day. Heat Stroke (aka: sun stroke): The signs and symptoms of heat stroke are hot, dry skin to the touch; reddish coloring; body temperature > 105 degrees F; no sweating; mental confusion; deep, rapid breathing that sounds like snoring progressing to shallow, weak breathing; headache; dizziness; nausea; vomiting; weakness; dry mouth; convulsions, muscular twitching, sudden collapse; possible unconsciousness. First aid for heat stroke is as follows: I. Immediately remove the victim to the support area; prior to entering the support area, remove and dispose the victim's chemical-resistant clothing. 2. Cool the victim rapidly using whatever means are available, including: shade; opening up and/or removing clothing; soaking clothing/skin with water and fanning; placing victim in vehicle using air conditioning on maximum. 3. Do not give drinking water to victim. 4. Treat for shock, if needed. 5. Transport the victim to the emergency room or call for emergency help; no exceptions for heat stroke victim. TRAINING REQUIREMENTS All staff working on-site have completed training in hazard recognition and basic health and safety issues as required by the occupational safety and health regulations contained in Title 29 Code of Federal Regulations Part 1910.120 (29 CFR 1910.120 (e)). All site supervisor personnel have completed the OSHA "8-hour Management/Supervisor Training" course. In addition, each employee will be familiar with the requirements of this HSP, and will participate in daily site activity and safety briefings. PERSONAL PROTECTIVE EQUIPMENT Based upon the hazard analysis for this project, the following Personal Protective Equip- ment (PPE) will be required and used. Changes to these specified items of PPE will not be made without the approval of the SSO.

Upgrade to level C will be determined by the level of contaminants detected with a MiniRam aerosol monitor or a photoionization detector. Level D PPE includes: • Safety boots and disposable boot covers • Hard hats • Protective eyewear • Tyvek coveralls • Vinyl or latex disposable gloves • Hearing protection (if needed around heavy equipment) Concentration levels that require respirator upgrades due to airborne dust are based on lead concentrations because lead has the lowest MCL of the contaminants of concern. Only NIOSH/MSHA approved respirators will be used. Action levels for upgrades are: .05 mg/m3 -0.5 mg/m3 0.5 mg/m3 -49 mg/m3 e!50 mg/m3 Respirator with dust and mist filters Hi-efficiency particulate filter on powered air purifying respirator Full-facepiece self-contained breathing apparatus, or supplied air full-facepiece Concentration levels that require respirator upgrades for volatile organics will be based on total volatile concentrations and measured with a PID. ENVIRONMENTAL MONITORING PLAN The potential hazards identified in the hazard analysis portion of this HSP determined the need for initial and ongoing monitoring for assessment of exposure to the hazards. Work zone monitoring during soil sampling will be accomplished with the use of a Victoreen Model 190 Radiation Survey and Count Rate Meter equipped with Model ll0D probe capable of beta and gamma detection. The instrument must be laboratory calibrated by the manufacturer within 6 months of use, employing appropriate calibration standard. In addition, a photoionization detector HNU Model 101 will be used, as well as an explosimeter. The explosimeter will be used to monitor explosive gas/air mixtures, and the percent of breathable air available. Due to the intrusive nature of the soil sampling and monitor well construction, organic vapor monitoring will also be performed using an HNU Photoionization Detector (PIO). The action level for use of full-face respirators with organic vapor cartridges is 10 ppm total organic vapors. Instruments for environmental monitoring will be calibrated prior to each day's use.

MEDICAL SURVEILLANCE REQUIREMENTS Medical surveillance is conducted as a routine program for all project field staff which meets the requirements of 29 CFR 1910.120 (f). There will not be any special medical tests or examinations required for staff involved in this phase of the project SITE CONTROL MEASURES A map of the site is included as Figure I. Work areas including exclusion zone, decon- tamination areas and support areas will be established on-site. These areas will be delineated depending on the specific field activities being conducted. The exclusion zone will be marked with yellow caution tape to allow access only to personnel with the proper personal protective equipment. All lunch and rest breaks will be taken away from the work areas, and preferably off-site for lunch breaks. Any and all support areas will be upwind of the field activities. Communication between field team members will consist of verbal communications aided by hand-held 2-way radios and hand signals (if Level C PPE is necessary). The nearest medical assistance is Rex Hospital. A map showing the direc- tions to the hospital will be posted at the site and is included as Figure 5. WORK PRACTICES Safe work practices are part of assuring a safe and healthful working environment. These practices are standardized for all field activities, and it is the responsibility of all project personnel to follow safe work practices when conducting field activities. Safe work practices to be employed during the entire progress of field work are as follows: I. Set up, assemble, and check out all equipment for integrity and proper function prior to starting work activities. 2. Do not use faulty or suspect equipment. 3. Use only new and intact protective clothing. Change the suit, gloves, etc. if they tear. BROWN AND CALDWELL 25 Healtl, 111M SafdJ Pia · N.,.,...,,_. 1991 ,, I, I I I ,, I I' :1 I' I, , ..

Do not use hands to wipe sweat away from face. Use a clean towel or paper towels. Practice contamination avoidance at all times. Do not smoke, eat, drink or apply cosmetics while in the contaminated areas of the site or prior to decontamination. Wash hands, face, and arms prior to taking rest breaks, lunch break, and leaving the site at the end of the work day. Check in and out with the SSO upon arrival and departure. Perform decontamination procedures completely as required by this HSP. Notify the SSO immediately if there is an accident that causes an injury or illnes& Use the buddy system when working in the contaminated areas of the site. 12. Do not approach or enter an area where oxygen deficiency or toxic or explosive concentrations of airborne contaminants may exist without the proper personal protective equipment and appropriate support personnel. 13. Use respirators correctly and as required for the work area; check the fit of the respirator with a negative or positive pressure test; do not wear respirator with facial hair or other conditions that prevent a face-to-facepiece seal; do not wear contact lenses when the use of a respirator is required. DECO NT AMINA TION Decontamination will take place in the decontamination areas established. All workers, PPE and sampling equipment leaving the work area will be decontaminated to prevent the spread of hazardous materials. Support vehicles are to be left outside the work area so that decontamination will not be necessary. There are no special emergency decontamination procedures anticipated for this project Personnel decontamination will be conducted at the point of egress from the exclusion zone. The decontamination line will begin with a soap and water rinse for outer boots and gloves. Following boot and glove decontamination, a garbage bag lined trash can will be set up for disposable gloves, boot covers and tyvek. Respirators will be removed after removal of disposable protective clothing. Between wearing during each work period, the respirators will be wiped clean with a damp cloth and alcohol swab. Following each days use, the respirators will be disassembled, washed, reassembled, inspected and fitted with new respirator cartridges. BROWN AND CALDWELL 27 Heolll, tllM S4/«, P'--N-i-1992 I I ,,, .,, I ,, I Sampling equipment will be decontaminated using the following procedures: I. Rinse with tap water to remove any gross contamination, using a scrub brush if necessary. 2. 3. 4. Clean with an Alconox and deionized water solution. Rinse with 10 percent nitric acid. Triple rinse with deionized water. 5. Spray with a solution containing 20 percent isopropyl alcohol and 80 percent deionized water and allowed to air dry. Sampling and drilling equipment will be steam cleaned prior to its initial use and between each sampling location. Excavation equipment will be decontaminated prior to egress from the work zone. Decontamination will consist of steam cleaning or pressure washing with potable water containing detergent (Liquinox), followed by a potable water rinse. If needed, difficult to remove soil will be scraped away prior to steam cleaning. EMERGENCY PROCEDURES In the event of an emergency on-site, the SSO will direct the course of action. It may be necessary for the SSO to depend upon the other on-site personnel for assistance. The SSO will call for emergency assistance if needed. As soon as practical, the SSO will contact the PM and the HSO. All staff assigned to this project will be briefed on the procedures and responsibilities for implementation. A map showing the location and route to the hospital is included as Figure 5, and directions to the hospital are listed as follows: On the site map, the Lot 86 site and the hospital are both highlighted with an arrow and black dot. Access to the hospital may be gained by leaving site 86 (via marked entrance/exit roads) and heading south to Old Trinity Road. After reaching Old Trinity Road, tum east (left) and travel to the intersection of OT and Blue Ridge Road. Tum north (left) and travel approximately 1.2 miles to the intersection of Blue Ridge and Lake Boone Trail. Rex Hospital will be on the northeast comer of this intersection. The SSO is trained in fust aid and CPR. A fust aid kit and fue extinguisher will be located in the support vehicle and decontamination area. During drilling activities, the emergency shut-off switch for the drill rig will be identified, and all field personnel working in the area will be informed of its location and function during the site safety briefing. During field activities, a mobile phone will be available within the designated support area of the site. A cellular telephone will be on-site at all times in the support vehicle. The emergency telephone numbers to be used to call for assistance are listed in the section on Key Personnel and Responsibilities BROWN AND CALDWELL 28 H-'tlt anti Safa, Pion • N._.., 1992 I I I I I I I.
