CHAPTER 1 -INTRODUCTION The Alaska Power Ji,uthority has prepared this best management practices (8MP) manual as one of a series of manuals to be used in design,ccnstructicn,opera- tion,and maintenance of Power Authority projects in A.1aska.This gr'1P manual identifies some of the major elements that comprise on-site management of hazardous materials,and presents gUidelines which reflect codes a~d regulations for accountability,storage,and disposal.Not 0.11 elements C'r guidelines will be appropriate for a particular site.In addition,federal,state and leca1 laws may impose specific requirements on particular PO\ller Authority projects or activities.This manual is not a substitute for case-by-case identification and compliance with all laws and regulations applicable to PO\ller Authority projects. The terms "hazardous materials"and "hazardous wastes"are used throughout this manual.For purposes of this manual,these are materials \lmich have potential to cause substantial harm to humans or the environment.However,because each environmental law may define "hazardous materials ll or "hazardous wastes ll in a different manner,this manual cannot provide a definition of these terms that will be accurate in all contexts. A substance or material is Ithazardous"when it meets one of the defined charac- teristics in anyone of several environmental laws and/or because it is actu~11y found on a list of substances or materials which the law defines as hazardous. To constitute a Ilhazardous waste",the hazardous substance must first bE:a "waste".Tf'e laws regulating hazardous wastes provide very specific legal definitions for what constitutes a waste.These laws are discussed in Chapter 4. -1- Since hazardous materials and hazardous waste management are heavily regulated at the federal and state level,permitting requirements are important in prcject planning.P,pplicCl.ble regulations and permitting requirements may determine the kind of hazardous materials and waste management strategies used for individual projects.The following are important factors that should be an integral part of Power Authority project planning: o Identify project goals and describe hazardous materials and waste generation necessary. ,.,.., o Identify statutes,regul ati ons and agenci cs whi ch 'regul ate ei ther the proposed activity or its impacts.In parti cul al~,determi nE: whether existing Power Authority permits control the activitit~s or impacts involved. o Compare burdens imposed by regul ati ons and/or permi ts for pro- posed activities and alternatives (including costs associated with modifying activities to reduce or eliminate requirements). o Develop and implement permitting strategy to obtain timely issuance of permits. Chapter 2 of this manual di scusses accountabil ity and safety elements common to on-site management of hazardousmateri a1s.Chapter 3 addresses storage of hazardous materi a1s with emphas is on the two types of products most common to construction projects in Alaska:1)explosives,and 2)petroleum,oils and lubricants.Chapter 4 discusses the requirements for identification,treatment, -2- - storage,and di sposa 1 of hazardous wastes.Regul atory authoriti es governing hazardous materials and hazardous wastes are listed in Chapter 5. -3- ----------~---------~--- - .- - CHAPTER 2 -ACCOUNTABILITY AND SAFETY All Power fl.uthority proJects will be required to develop and implement an C1.ccurate accounting and product information system fer any fuel or hazardous materials from delivery to the site,through storage and use,to final disposal. Training programs must also be designed and conducted to assure that fuel and hazardous materi a1s \'Ji 11 be appropriately hardl ed to protect both human health and the environment . 2.1 FUEL ANDHAZAPDOUS f·~ATERIAlS TRACKING AND INFORMATION SYSTEM P product tracking and information system must bp.developed to alert workers of proper procedures for handling hazardous materials and hazardous wastes and potential environmental and health dangers if mishandled. Equally important,the system must facilitate compliance with the "cradle- to ...grave"reporting provisions of the Resource Conservation and Recovery Act (RCRA)and its implementing regulations discussed in Chapter 4. The most immediate but least detailed form of product information is the manufacturer's direct labeling of containers.Proper labeling should contain a description of the product,recommended uses,recommended storage conditions,and safety precautions. Individual data sheets available from the supplier for specific products provide the next level of information.Such sheets usually contain typical -4- - - - - - "".• - properties,recommended storage conditions,safety procedures,environmen- tal considerations,and spill control procedures. A third level of information involves the manufacturers I material safety data sheets (OSHA Form 20).Concise chemical and physical properties such as specific flammability,explo.sjvity,chemical reactivity,or toxicity are reported.Also included are special protection or precautions required. Figure 1 depicts an example of a product tracking and information system for a project whose hazardous wastes are transported offsite to an EPA- approved treatment or disposal site.The following sections discuss the functional relationships and components of thp system and the three princi- pal positions (for purposes of this example designated as ll~lateria1s ~ Coordinator","Issue/Return Coordinator[s]",and "Disposal Coordinator") responsible for implementation. 2.1.1 Procurement and Receipt (Figure 2) Product tracking and information dissemination begins with a re~uest for requisition of materials.These requisitions are reviewed by the Materials Coordinator,who is fully cognizant of applicable state and federal regu- lations governing hazardous materials,and who has access to product information provided from manufacturers or other sources.The requisitions are forwarded to the procurement office for purchasing and are accompanied by copies of product information data.Completed copies of purchasing documents along with the product information are sent to the receiving -5- Fuel &Hazardous Materials Requisltfons ..

Fuel and hazardous materials arriving onsite at project receiving are checked for labels and must be accompanied by a manifest containing product information from the manufacturer.Incoming shipments are checked against the receiving office 1 s copies of purchasing documents . Copies of receipt documents are sent to the procurement office and tre Materials Coordinator.A copy of the manifest accompanying the shipment is a1so forwarded to the Materials Coordinator. 2.1.2 Storage (Figure 3) Once the material has been received onsite.the Materials Coordinator is responsible for distributing appropriate documentation to the product supplier,applicable regulatory agencies,and the Issue/Return Coordina- tor(s)in charge of recordkeeping at each product storage facility.The Materia 1s Coordinator also sends product informati on dat.a to the Oi sposa 1 Coordinator,and to project safety and medical personnel. The actual material,accompanied by a copy of the manifest,is delivered to the appropriate storage facility by the transporter where it is off-lo2ded and stored according to the instructions and \lJClrnings contained on the manifest,container labp.ling,and product information distributed at the time of purchasing. -8- Receiving MATERIAL INVENTORY/RECORDS PRODUCT INFORMATION ALASKA POWER AUTHORITY STORAGE FIGURE 3 .- - All requests from users for products stored at the site are documented through the Issue/Return Coordinator responsible for the product.This coordinator is also responsible for informing users of potential hazards associated with the product.Prcducts returned to the storage facil ity (i.e.unused explosives to be returned to the magazine)are also documented through the Issue/Return Coordinator. 2.1.3 Disposal (Figure 4) Wastes generated from project activities or defective products are deliver- ed by the users to the Disposal Coordinator who documents their arrival at the waste staging area at each pl'oject site.Copies of records of incoming materials to the waste staging area are sent to the Materials Coordinator. The Disposal Coordinator is responsible for identifying and segregating hazardous wastes from nonhazardous wastes in compliance with the RCRft regulations for hazardous waste determination (40 eFR 262.11),identifica- tion,and characterization (40 CFR 261).The Disposal Cccrdinator shall arrange for transport and disposal of hazardous wastes or defective prc- ducts through an EPA-approved tral'1sporter to either the vendor of the defective product or an EPA-approved treatment and disposal site,as appropriate.Offsite shipments are packaged andlabelled according to federal Department of Transportation regulations and are accompanied by an approved uniform manifest that is completed by the Disposal Coordinator (40 CFR 262,Subpart B;see 49 CFR 172,173,178 and 179).A copy of the manifest is sent to the Materials Cccrdinator who is responsible for fulfilling reporting requirements to applicable regulatory agencies and the -10- MATERIAL INVENTORYIRECORDS PRODUCT INFORMATION Vendor Staging Area EPA Approved Treatment and Disposal Sito ALASKA POWER AUTHORITY DISPOSAL FIGURE 4 original supplier of the material and for compliance with the ongoing RCRA recordkeeping and reporting requirements set out at 40 CFR 262,Subpart D. 2.2 PERSONNEL TRAINING AND SAFETY PROGRAM Personnel assigned to handling hazardous materials or hazardous wastes must complete a training course to ensure that they are aware of hazardous materials management procedures and safety measures.Training for person- nel handling or using hazardous materials must include at least the follG\<./o- ing elements (8 AAC 15)~ o Methods and observations that may be used to detect the presence or rel ease of a hazardous substance in the work area (monitor;ng programs,odors,etc.) o Potential health hazards (definitions and product identification as presented on Material Safety Data Sheet or equivalent)in the work area o o Personal protection equipment Appropriate handling procedures c Recordkeeping and inventory procedures o Preventive maintenance -12- .... .....

Training programs required for personnel handl ing hazardous wilstrs are detailed in the RCRA regulations at 40 CFR 265.16.The training prcgrC1m must comply with RCRJ1.training requirements and should be designed to allow facil ity personnel to respond effectively to emergencies . -13- CHAPTER 3 -STORAGE OF HAZARDOUS MATERIALS This chapter is directed principally at facility designers responsible for the design of hazardous materials storage areas.The guidelines presented are not intended to be all-inclusive and are based on codes cmd regulations current at thE~time of publication.Applicable federal,state,and local regulations must be determined and complied with on a case-by-case basis.Storage regulations for hazardous wastes are discussed in Chapter 4. - - - - 3.1 GENERAL STORAGE GUIDELINES Storage faci 1ities for hazardous material s must be designed to segregate materials which may react upon contact with one another.Minimum dista.nces between storage areas and residential facilities,wells,public roads, property boundaries,and natural resource features (such as waterbodi es) are specified for storage of many products.In addition,the facilities must be desi gned and constructed to protect the materi a1s from wi 101 He intrusion,weather,and any other changes which could affect cowposition or sensitivity.Showers,eye-wash stations,and fire protection equipment should be incorporated into the design. 3.1.1 Above/Underground Bulk Fuel Storage In general,above-ground storage of bulk liquids.particularly combustible liquids,must be in containers meeti~g certain specifications.Additional- ly,the bulk storage facility is generally required to have a containing berm constructed around it and to be of sufficient size to hold and retain -14- - - .,... - all of the contents of the largest on-site storage container.Underground storage of bulk liquids also requires tanks meeting certain specifications, as well as cathodic protection for metal tanks.Undergrourd tanks exceed- ing a certain size must have monitoring devices to detect leakage.r~ore specific guide1ines for bulk fuel storage are presented in Section 3.2. 3.1.2 Exp10sives Explosives are stored in either permanent or portable magazines that are designed for the types of explosives that may be stored in them.Specific guidelines for storage of explosives are contained in Section 3.3. 3.1.3 Indoor Storage of Flammable/Combustible liquids According to 29 CFR 1926/1910,the amount of flammable/combustible liquid that may be stored in c building depends upon the buildingrs fire resis- tance rating and the pres~nce or absence of an automatic fire extinguishing system.For instance,facilities of less than 150 square feet with a I-hour fire resi stance rating and an automati c fi re extingui shing system may store up to 750 gallons.The same facility without an automatic fire extinguishing system is limited to a storage capacity of 300 gallons. Containers holding more than 30 gallons may not be stacked. Ground floor storage is preferred for f1ammable/combustible liquids.At least one outside wall is required for connected flammable stora~e rooms. Other structural characteristics include the following: -15- """" -o Blow-out panels (recommended) o Impermeable wall and floor joints o Self-closing fire doors o At least one exterior door (preferred) o A drain and diking system at least 4 inches high in front of all openings;drains must connect to a safe outside collection area -o Unobstructed 3-foot wide aisles .- c Secure shelving and racks Mechanical and electrical provisions to be included in the design of storage facilities for flammable/combustible liquids inclUde the following: o An alarm system o Ventilation with at least a ten times per hour air turnover o Exhausts from the floor,ceiling,and all possible dead-air spaces o Flame arrestors in vents -16- - - o Air intake directly from the outside within 1 foot of the floor level;with proper dampers,air may come from inside a connected buil ding. o Temperature and humidity control - -- o o Adequate lighting;s~itches should be installed on the outside of the room or building. Adequate grounding of all racks,scuppers and other conducting elements - ..... 3.1.4 Corrosives Corrosives must be stored in a dry,cool,ventilated (at least 6 times per· hour air turnover)area and must not be directly exposed to sunlight. Sprinkler systems should be installed.All corrosives must be stored in contai ners recommended by the manufacturer.Temperatl!l~e and hum;Gity control must be provided.Fans must be direct drive,non-sparking and corrosion resistant. 3.1.5 Reactive Chemicals Reactive chemicals (including oxidizing and reduction agents,complexers, etc.)must be provided with storage space in a cool,dry,well-ventilated area away from direct sunlight.The storage area must be fireproof and protected from extreme and rapid temperature changes.As these materials -17- - - - - - - - may be water-sensitive,it ;s advisable that no water service be provided to the building.The use of wood for shelving,flooring,etc.is not recommended since oxidizing and reactive chemicals may react with organic materials. 3.1.6 Compressed Gases Cylinders used for the storage of fuel gas or oxygen should be stored in well-ventilated areas.If the area is used for other purposes,storage of gas is limited to 2000 cubic feet of acet.ylene or non-liquified flammable gas.The cylinders must be separated at least 20 feet from flRmmable and combustible materials.The storage area should be located ~here cylinders will not be knocked over or damaged by passing or falling objects.For outside storage,provisions must be made for ease of access and handling during all seasons and for protection against wildlife intrusion.Outside storage areas should be located well away from traffic lanes and be de- signed with an adequate cover which win withstand projected snow loads and winds. 3.2 PETROLEUM,OILS AND LUBRICANTS (POL) Typical POL products that will be stored and used at Power Authority project sites are diesel oil,gasoline,aviation fuels,hydraulic fluids, anti-freeze,lubricants,solvents,and rust inhibitors.~~ost POL products are flammable in different degrees varying from explosive in nature to merely flammable (classifications of combustible and flammable liCluids are shewn on Table 1),are classified as caustics and irritants to human and -18- - I~ TABLE 1 CLASSIFICATIONS OF COMBUSTIBLE AND FLAr·1MABLE LIQUIDS Combustible Liquid.A liquid having a flash point at or above 100°F (37.8°C).

Class 18 shall include those having flash points below 73 c F (22.8°C)and having a boil ing point at or above lOO°F (37 .8°C). Class IC shall include those having flash points at or above 73 c F (22.8°C) and below IOO°F (37.8°C). Source:National Fire Codes (NFPA 30) -19-· - ..- - - - animal flesh,and can be carcinogenic.All POL products are considered potential pollutants. 3.2.1 Storage Containers The National Fire Protection Association standards (r{FPA 395)are C1.ppl ic- able to the storage of flammable and combustible liquids (i.e.POL pro- ducts)at rural construction projects where it is customary to obtain fuels in bulk and dispense or transfer under control of the owner or contractor. (The standards do not apply to storage of 25 gallons or less of flammable and combustible liQuids in containers not exceeding 5-gallon capacit.y,or to -fuel oil tanks and containers connected with oil burning eqLiipment as covered in NFPA 31.) ~ndividual containers constructed of metal or other materials approved by the U.S.Department of Transportation may be used to store 60 gallons or less of flammable and combustible liquids.These individual containers must not be interconnected.Drumruns,if stored horizontally,should not exceed two drums wide and three drums high with a minimum of 5 feet between runs.All drumruns should be placed on 4x4-foot dunnage and be chocked at both ends.Outside storage for containers of Class I flammable liauids must be at least 10 feet from any buil di ng and well away from traffi c lanes;inside storage may be in a building us~d exclusively for storage of flammable and combustible liquids that is located at least 10 feet from any other building.Buildings used for storage of Class I flammable liquids must have at least two 64-square-inch vents placed at floor level for cross-ventilation. -20- - - Flammable and combustible liquids of 61 to It100 gallons may be stored outside of buildings in tanks constr'ucted of at least 14-gauge steel.The tanks must be of single-compartment design.Joints must be riveted and caulked,riveted and welded,or welded.Tank heads over 6 feet ip diameter must be di shed,stayed t braced,or reinforced.Each tank must have a free opening vent of the following minimum nominal pipe size to relieve vacuum or pressure: H ? '- 2! 3 Vent Diameter (inches) up to 275 276-660 661-900 901-1100 Tank Capaci ty (gallons) ,-. - These tanks and any transfer operation must then be at least 40 feet from any building and 100 feet from any well or water supply source.Stationary tanks must be mounted on timbers or blocks approximately 6 inches in height to protect the bottom of the tank from corrosion. The largest quantities (perhaps exceeding SOtOOG gallons at anyone on-site facility)of POL products stored'at Power Authority project sites will consist of diesel oil,gasoline,and aviation fuels.These bulk products will be stored in either double-walled steel tanks or hypalon bladders - des i gned and constructed accordi ng to NFPA 30 standards.Above-ground tanks and bladders of the types most likely to be used to store these products must be located at least the minimum distances shown on Table 2 from property lines,public ways,and buildings,and at least 1,500 feet from waterbodies.In addition,each above-ground tank or bladder must be separated from another according to the minimum distances shown on Tnble 3. --21- TABLE 2 MINIMUM DISTANCES RELATIVE TO PROPERTY LINES, PUBLIC WAYS,BUILDINGS ,~.

High-liquid-level alarms with audible and visual signal,high-level pump cutoff devices,a visual system for determining 1 iquid level s ~and other safety devices must be provided.Bladder storage areas must be fenced. Lighting should be prOVided for POL facilities used as project service stations during periods of darkness.Storage facilities must be protected against electrical spark or static discharge and,when practical,shoulc' also be fitted with lightning arrestors.Fire protection measures should -24- - ..- - - 3.3 include alarm systems,halon systems (where practical),and non-freezing extinguishers readily available for Class A,Band C fires . Transfer stations must be sized to accommodate the numbers of pro.~ect vehicles and construction equipment for each specific project.All dis- pensing facilitif's must include anti-stc.tic devices and bondin0 wire to facilitate proper grounding.For those sites where petroleum products are delivered by marine tank vessels with a capacity of 10,500 gallons or mere, the equipment requirements administered by the U.S.Coast Guard (33 CFR 154)must be incorporated into the design. EXPLOSIVES Explosives likely to be required for power projects include,but are not limited to: Dynamite and other high explosives Pellet powder Initiating explosives Detonators Fuses Cartridges for propellant activated power devices Detonating cord Igniter cord Igniters Primers Smokeless propellants Squibs ...... - Explosives are classified according to the degree of hazard they present . Glass A explosives present a detonating or otherwise maximum hazard and include such substances as dynamite,nitroglycerin,picric acid,lead -25- - - ,~ - - oxide,fulminate of mercury,blasting caps,and detonating primers.Class B explosives,such as propellants,present a flammable hazard.Class C explosives,which present a minimum hazard,include certain types of manufactured articles containing Class A or Class B explosives,or both,as components,but in restricted quantities.The final classification, oxidizing-material,is a substance that yields oxygen readily to stimulate the combustion of organic matter. 3.3.1 Storage of Explosives and Blasting Agents Explosives are stored in either permanent or portable magazines that are designed for the types of explosives that may be stored in them.Magazine classifications are as follows: Type 1 Magazine--A permanent magazine for the storage of explosive materials that are bullet sensitive such as dynamite and detonators which will mass explode. Type 2 Magazine--A portable or mobile magazine for outdoor or indoor storage of explosive materials that are bullet sensitive such as dynamite and detonators which will mass explode. Type 3 Magazine--A portabl e magazine for the temporary storage of explosive materials while attended.An example is a nday box"at the site of blasting operations. -26- - - - Type 4 Magazine--A permanent,portable,or mobil e magazine for the storage of low explosives,explosive materials that are not bullet sensitive,or explosive materials that will not mass explode. Type 5 Magazine--A permanent,portable or mobile magazine for the storage of explosive materials that are not bullet sensitive.Type 5 magazines include tar:l<s,tanl<trailers,tank trucks,semi-trailers, bulk trailers,bulk trucks and bins. ftl'1monium nitrate,which is a common bl,e.sting agent,should not Of::acceptfd for storage when the temperature of the product exceeds 130°F.If stored indoors,ammonium nitrate should be stored in a separate building or be separated by approved firewal1s of not less than I-hour fire-resistance rating from organic chemicals,acids,other corrosive materials,materials that may require blasting,compressed flammable gases,and flammable and combustible materials.Sulphur and finely divided materials should not be stored in the same building with ammonium nitrate. Unless constructed of non-combustible material or unless adequate facili- ties for fighting a roof fire are available,bulk storage structures for ammonium nitrate should not be over one story in height.Not more than 2,500 tons of bagged ammonium nitrate should be stored in a structure not equipped with an automatic sprinkler system.Bags of ammonium nitrate should not be stored within 30 inches of building walls and partitions.

Hazardous wastes!.as defined in the RCRA regulation,will not be treated or disposed of at Power Authority project sites.Hazardous wastes will be identi- fied by the Disposal Coordinator as described in Chapter 2,segregated from f'1on-hazardous wastes,and transported offsite by ali censed trilnsporter to an EPA-permitted hazardous waste treatment,storage and disposal site. Prior to transport,hazardous wastes may be accumulated (i.e.stored)onsite for 90 days or less without obtaining a permit from EPA,provided that the generator (i.e.those who produce hazardous waste)complies with the RCRJl,regulatirlls app 1 i cab 1e to short-term storage (40 CFR 262.34).Genera tors who accumul ate ~ waste for greatel~than 90 days ,are subject to EPA permitti ng requi rements and additional regulations applicable to hazardous waste facility operators (40 CFR 264 and 265).The Power Authority intends that all hazardous wastes generated from a project will be transported offsite withi n 90 days. It is important to note,however,that HeRA also imposes comprehensive and detailed requirements on generators who store hazardous wastes onsite for 90 days or less (see 40 CFR 262).The RCRA generator regulations at 40 CFR 262 require generator's to conduct hazardous waste determinations (see Chapter 2), obtai n EPA i dent"ifi cati on numbers,and comply with manifesting,pre-transport, recordkeeping and reporting requirements.Additionally,on-site storage for 90 days or less must be in accordance with RCRA container management Cl,nd inspection (40 CFR 265,Subpart I),tank storage (40 CFR 265,Subpart J),preparedness and -41- - - prevention (40 CFR 265,Subpart C),contingency planning and emergency proce- dures (40 CFR 265,Subpart D),and personnel training requirements. Thi s manual is not intended to serve as fi el d gui dance on hazardous waste management.The foregoing is a brief overview of some of the regulations applicable to hazardous waste identification,treatment,storage,and disposal.
