BACKGROUND Revision No 0 Revision Date October 1 1998 Page 4 of 17 This plan describes the air emission control and momtonng program to be conducted during the one -time demolition event to fel the stack and recovery building at the former Rayomer Port Angeles pulp mill site. The approach and procedures included in this plan are intended to expand upon and augment the ongoing air momtonng program implemented for site dismantling activities, as set forth in the fina Ambient Air Momtonng Plan (Foster Wheeler Environmental 1998) 1 Implement effective air emr sion control procedures dunng the stack and recovery building demolition event; 2. Monitor ambient air quality for potential air pollutants related to this event; 3 Quantify potential offsite •tr2 nsport of emissions .associated, with the event; and 4 Verify the- effectiveness -of mission ,control methods used. Rayomer received approval fror n the City of Port Angeles in July 1997 to dismantle its former pulp mill facility Following th .s approval, Rayomer voluntanly committed to develop and implement an air momtonng prl)gram. Air momtonng commenced in October 1 -997, and is currently ongoing for the genem1 site dismantling activities. The Rayomer site is a former pulp mill facility located at 700 North Ennis Street, Port Angeles, WA. The facility was origmall y constructed in 1929 and remained in operation until 1997 The total site is approximately 70 ages and is bordered to the north by the Strait of Juan de Fuca, and to the south by a high .bluff leading up to commercial and residential areas. Olympic Memonal Hospital is located on top of thl: bluff to the southwest of the site. 2.2 ONGOING EMISSION CONTROL AND MONITORING PROGRAM 2.3 RESULTS BECALVIN\VOL2 \WP \I834 \I2394.DOC 5/27/98 Revision No 0 Revision Date October 1 1998 Page 5 of 17 The stack and recovery building are located on the northwest corner of the site, and are surrounded landward by approximately 11 acres of mostly open areas that are the former locations of processing and stor2.ge areas that have been dismantled. The dismantled processing areas are further surrounded by z pproximately 60 acres of former parking lots, roadways, empty storage lots, and undeveloped wooded areas A. comprehensive program to control air emissions is being implemented during the dismantling and cleanup activities at the site. To ensure that the emission control program is effective, a network of air monitors surrounding the site collect samples on an ongoing basis which are tested for materials of concern that could be generated from site activities. The air monitoring program commenced shortly after the mill dismantling started, and will continue throughout site dismantling and cleanup activities. A team of Rayonier environmer tal personnel, dismantling contractors, and consultants are responsible for implementing the air_ monitoring program and air emission abatement activities (e g., dust during dismantling. Th&U S Environmental Protection Agency (EPA) also conducts air monitoring activiti s.as part of their oversight role for the dismantling work. The results of the air_momtonng are reported the Washington State Department of Ecology (Ecology), EPA, the City of Port Angeles, the Agency for Toxic Substances and Disease Control (ATSDR), and are placed in local libraries for public review Since the dismantling began, ON er 500 air samples have been collected and analyzed for potential constituents of concern at the site Samples are tested for particulate matter (dust), dioxins and furans (from hog fuel boiler ash), or lead. In addition, visual momtonng is conducted during all asbestos dismantling activities. The results of the tests are compared to air quality action levels, which are levels the EPA consi -lers acceptable for people to breathe over a lifetime without any health effects. The results of the first ten months of momtonng have found that all air samples are well below the air quality action levels. The highest detected particulate matter levels are less than half the \\BECALVTN\VOL2 \WP \1334 \12394.DOC 5/27/98 Revision No 0 Revision Date October 1 1998 Page 6 of 17 action levels, dioxins and furans are typically 1,000 times lower than the action levels, and lead was not detected in all but one of I over 100 samples tested for lead. In summary, the air emission control program being implemented by Rayomer has been successful in controlling the releases of airborne matenals from the site dismantling activities. The air momtonng program has confirmed that there has been no detected release of air contaminants from the site that vyere above action levels that may pose a threat to human health. The momtonng program remains; in effect, and results of the ongoing monitoring will continue to be provided to regulatory agencies and the public for review 3 PROJECT ORGANIZATION AND RESPONSIBILITIES The project team for the stack and recovery building include contractors, regulatory agencies, consultant and analytical laboratory support, and Rayomer environmental managers. A list of the project team and their responsibilities are presented in Table 1 Rayomer will with the EPA, Ecology, Coast Guard, and the of Port. Angeles for project review, oversight, and observation. This plan and subsequent air momtonng data reports are provided to Ecology, EPA, and ATSDR. EPA also conducts air monitoring activities as part of their oversight role for the dismantling work. The mill dismantling contractor, ICONCO, has overall responsibility for the stack and recovery building demolition. They have prepared a project- specific demolition plan that lays out the step -by -step procedures for planning, preparing for, and executing the stack and recovery building demolition (ICONCO 1 998) ICONCO has hired Controlled Demolition, Inc (CDI) with the responsibility for- planning, placement, and detonation of the explosives to be used to fell the stack and recovery building. Recognized worldwide as the founder of and leader in commercial explosive demohtiol technology, CDI will apply its experience via state -of -the art explosive techniques to safely and successfully achieve the required demolition results Table 1 Project Team —Stack alLd Recovery Building Demolition Event Team Member ICONCO Controlled Demolition, Inc.

AIR EMISSION CONTROL PROGRAM 4 1 SITE AND STRUCTURE CONDITIONS Revision No 0 Revision Date October 1 1998 Page 8 of 17 The site areas where the stack and recovery building drop zones are located are shown on Figure 1 The drop zone areas have been cleared of former structures. For the stack, the direction of fall has been selected so that much o f the drop zone is over concrete roadways. For both the stack and recovery building drop zone:;, all exposed soil surfaces will be covered with clean fill material. Fugitive dust and particulate miter generated during the stack and recovery building demolition represent the most probable source of air emissions. Other constituents that have been monitored as part of the ongoing air momtonng program include dioxin/furans and lead. Dioxin/furans are associated with the ash generates l from the hog fuel boiler air scrubber facilities (not the recovery boiler) The hog fuel boiler scru ober ash was handled in specific, limited areas of the site, and these areas and equipment were.'leaned ..the ash was disposed, offsite prior to shutdown of the facility The ,ash;was.not.handle•i withm•the drop_zones.of.either the stack orrecovery building. Lead is associated with the internal hmngs of the now dismantled pulp digesters. Lead abatement activities occurred in areas outside of the drop zones. Based on the fact that neither the hog fuel boiler scrubber ash or lead containing materials were handled within the drop zones, coupled with the plan to cover e ::posed soil surfaces, the drop zones are not considered a source of dioxm/furans or lead. The stack is a 300 foot -tall reinf>rced concrete structure with an internal fiberglass reinforced lining. The stack does not conta in refractory back or other materials that can cause high dust levels, and did not contain any lied-containing materials. EPA conducted testing of the stack lining for dioxinifuran compoun is. The EPA testing found that the stack is not considered a significant source of dioxm/fura \\BECALVIMVOL2 \WP \1834 \I2394.DOC 5/27/98 0 4C107 811, Scale in feet v./HEELER ENVIRONMENTAL CORPORATION Strait &Juan de Fuca Stack Note L Station TSP2 and Pllf2 are mobile and will be located at downwind location on the day of event 2.

No lead containing matenal was identified at the boiler during the mill site lead survey The reco very boiler located in the building generated a low volume ash stream that was distinctly differer t in character to the hog fuel boiler scrubber ash. EPA conducted testing of the recovery boiler ash for dioxin/fill compounds. The EPA testing found that dioxin/furan levels were e Ktremely low in the recovery boiler ash. Consequently, the recovery boiler is not considered a source of dioxm/furans or lead. Air emission control methods are implemented during all dismantling activities that have the potential to generate air pollutants. Specific air emission control measures to be taken during the stack and recovery building demolition are listed on Table 2. 4.3 ALTERNATIVES I ANALYSIS Worker safety was a "key ssue used to select the one -time demolition event to fell the stack and recovery building. In adc.ition, the one -time demohtion event reduces the time duration of dust generation to a matter of minutes, compared to one to two months for alternative dismantling methods. Alternative methods of stack demolition, such as removing the stack in sections using jack hammers, would res llt in workers suspended 300 feet m the air, where they would be exposed to extreme safety hazards and extreme weather The same worker dangers would be associated with removm the recovery building in sections, where workers would be 200 feet in the air conducting torch cutting for structure removal. Based on the significant improvement in worker safety, and no an icipated increase in environmental impacts, the one -time demolition event was selected as the appropnate.method for this demolition project. 1 Revision No 0 Revision Date October 1 1998 Page 11 of 17 Table 2.

Other constituents that have been monitored as part of the ongoing air monrtonng program include dioxm/furans and lead. These three constituents will be monitored during the stack and recovery building demolition. Although neither the drop zones, the stack, or the recovery building are identified as sources of dioxm/furans or lead, thee constituents are included m the air monrtonng program based on their past use at the site. Air monrtonng will be conducted in general conformance with the procedures and protocols set forth in the Ambient Air Momtonng Plan, with project- specific provisions as described herein. Four air monitoring will be, operated,: as currently conducted. The EPA is intending to operate an air momtonng..station at the Olympic Memonal.Hospital. Air quality sampling will be conducted according to-EPA guidance (EPA 1988, 1994, 1995, 1997), and sample analysis will be conducted in accdrdance with EPA and standard laboratory protocols, as called for in the Ambient. Air Momtonng Plan. The meteorological monrtonng, quality assurance /quality control procedures, and data quality objectives will be implemented as set forth in the Ambient Air Momtonng Plan. 5.2: EVENT SPECIFIC ACTIVITIES For-the stack and recovery boiler demolition_ event, the sampling station location and sample duration protocols established in the Ambient Air Monitoring Plan will be adjusted, as described in the. following subsect ions. 5.2.1 Sampling Station Location Four sampling stations will be located (Figure 1) as they are currently located as part of the ongoing air monrtonng program. The adjustment to this program will be for Station Number 2, which will be modified to facilitate mobile location on the day of the demolition event.

Monitoring will be conducted throughout the 24 -hour period around the demolition: event. To maintain adequate air flow rate through the samplers during the event, the sampling filter /cartridge may be.changed during the event on one or more of the sampling stations. If the sampling filter cartndge is changed during the event, both samples will be laboratory analyzed and included in quantifying the air emission levels dunng the event. Meteorological data will be collected on a continuous basis throughout the duration of the air momtoring. 5.3 .AIR QUALITY AC' 'ION LEVELS Air quality action levels ai e identified to use as an indicator of the effectiveness of onsite emission•.control methods used dunng dismantling and cleanup activities. The action levels for the potential air pollutants momtored under this plan, and the method used to establish the action level, are presented in the Ambient Air Momtonng Plan, and are reproduced in Table 3 of this plan.

In the event of wind speeds in excess of 20 mph, safety concerns due to the )otential for impacts to structure lay down will cause the scheduled demolition time to be delayed until the wind speeds have diminished. Heavy cloud cover can result in excessive compressive force to be trapped by the clouds. The scheduled demolition time will be delayed until the cloud cover has dissipated. Electrical storms would delay the demolition event. 6.3 DATA ASSESSMENT AND REPORTING Revision No 0 Revision Date October 1 1998 Page 17 of 17 Data assessment and reporting will be conducted m accordance with the applicable sections of the Ambient Air Momtormg Plan. The analytical data will be promptly reviewed and validated when received from the laboratory to ensure that only data meeting established cntena for data acceptabilityare considered for evaluation and reporting. A data report will be produced and transmitted to Ecology, EPA, other agencies; and the public as defined in the Ambient Air Momtonng Plan. Labora Dry analytical data, field data sheets, and all sampling train calibration data will be provided as a pendices to each sampling event report. 7 REFERENCES EPA (U S Environmental Protection Agency) 1988 Compendium of Methods for the Determination of Toxic Organic Compounds in Ambient Air, 2nd Supplement.

Personnel Safety 5.19 METHODS AND PROCEDURES ICONCO, Inc. has chosen to fall the Rayonier (Port Angeles) Recovery Boiler and Stack by use of explosives. The choice of explosive tripping method has been made for the following reasons. I. Personnel Safety II. Task Duration III. Se of Work Alternative meth Dds to explosive use for both the stack and the recovery boiler demands a much higher labor exposure. Methods such as picking sections of recovery boiler down with a crane or hand chipping the stack would require people working from heights up to almost 300 feet. At these heights, individuals would be exposed to extreme weather conditions associated with Port Angeles during fall and winter months. In addition to a much greater labor exposure, alternative methods also require the use of a crane making strategic picks of 10 tons or greater at 200 feet elevation while coordinating with workers using hand held cutting torches making final cuts. Explosives eliminates the majority of high work and use of a crane while reducing the number of labor hours (at heights of up to 300 ft.) exposed to winter weather conditions. II. Task Duration The use of explosives reduces the actual demolition time of the stack from 40 60 days to less than a 5 minute task. The same duration s can be approximated for the recovery boiler The time analogy used above is for actual wrecking work. Prep time for the stack and boiler is expected to be approximately two weeks. III. Sequence of Work It is anticipated that both structures (Recovery Boiler Stack) will be tripped at the same time. Simultaneously tripping both structures provides for improved security, air mor itoring, public meetings, blasters mobilization, explosive storage and project interruptions. 6 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 5A.1 INTRODUCTION The stack demolition consists of using explosives to fall a 300' tall concrete stack with a fiberglass interior liner The explosives work will be done under the supervision of ICONCO using a subcontractor, Controlled Demolition Inc. (CDI) CDI has extensive experience in similar projects and a reputation for working safely and effectively The stack will be felled eastward towards the machine room and north end of the bleach plant building. There are no known underground utilities in the area. ICONCO will assist CDI in their work, provide coordination with all parties and provide site security during explosive operations. 5A.2 DUST CONTROL The dust while demolishing the stack will be handled by a "wet method' Starting the day before the shooting. The area where the stack will land will be thoroughly wetted. Prior to the shot, we will place a nozzle connected to two 1 -1/2" firehose just outside of where the top of the chiinney will land. The nozzle will be mounted on a stand and provide a wide spray of water onto the landing area. By providing a cover of water as the stack lands, we will min mite the release of additional dust particles caused by the fracturing of the concret 7 1 1 5A.3 CDI WORK PLAN CONTROLLED DEMOLITION, INC 2737 MERRYMAN'S MILL ROAD PHOENIX, MARYLAND 21131 USA PLAN E EXPLOSIVES FELLING OF 300 F7 IEINFOICED CONCIETE CHIMNEY LOCATED AT THE RAYONIER MILL PORT ANGELES, WASHINGTON FOR ICONCO 5409 OHIO AVENUE SOUTH SEATTLE, WASHINGTON 98134 8 DURE 1 I. SCOPE Controlled Demolition Incorporated (CDI) is submitting a proposal to perform the explosives felling of the chimney scheduled to be demolished at the Rayonier Mill located in Port Angeles, Washington. Our representatives have reviewed the site, the subject chimney and adjacent improvements to remain. We feel that our proposed methodolog will allow for a more efficient, timesaving and safer demolition as compared to conventional techniques used on structures of this size. CDI's proposed explo!ives demolition work on the chimney is backed by over 40 years of explosives experience in the demolition of over6,000 structures, nearly 600 of these structures being chimneys and of those, 150 reinforced concrete chimneys which are generally similar in construction to the one referenced above. All of the chimney demolition projects were completed without damage to facilities scheduled to remain or injury to personnel. Recognized worldwide as the founder of and leader in commercial explosive demolition technology, CDI will apply its experience via "state of the art" explosives techniques to safely and successfully achieve the required demolition results on this project. CDI intends to modify the chimney by cutting slots to create "columns" in the direction of fall. CDI will then eliminate these "columns" during the final explosives sequence to induce rotation of the chimney allowing them to fall full height into the fall are. II EXPLOSIVES DEMOLITION PREPARATION Safe preparation and structural pre removal will be designed on the basis of available drawings of the chimney, historic wind criteria and CDI's on site observations. Further details will be finalized during preparation activity on site. A. Utilizing hand held pneumatic drills, the reinforced concrete shell will be drilled. At this point in time, CDI anticipates that approximately 250 -350, horizontal, 1 -3/4" 'diameter holes will be drilled into the base of the chimney B Selected vertical reinforcing rod in the rear of the chimney opposite the direction of fall will be exposed for subsequent cutting just prior to demolition. The cutting of this bar will reduce the tensile capability of the rear of the stack, but will not adversely effect the compressive capability of the concrete. This will allow CDI the ability to fully control the speed of rotation guaranteeing that the chimney will land in the proposed fall area. 9 C. Beginning approxii lately four (4) hours prior to the demolition. 1. CDI will install the explosives and explosives initiation system (see Item V Initiation System) 2. CDI will re -check the final placement of all explosives charges. 3 Protection of adjacent property will be performed by Iconco 4. Iconco's forces will begin placing the protective cover over the base of the chimney as required. D Beginning two (2) hours prior to the demolition. 1 CDI will re -check the circuits and inspect all protective cover at the base of the chimney 2. CDI will pre -burn rebar in the rear of the chimneys to facilitate rotation. E. In the event that winds (as measured at ground level) are in excess of 20 mph at the scheduled demolition time, CDI reserves the right to delay the shot until winds have either diminished or changed quarter III TYPE OF EXPLOSIVES The following are the types and approximate quantities of explosives to be used on this project: A. Non electric, short period blasting caps will be used to initiate the primary explosives. Approximate explosives weight in these initiators is less than 01 lb total. B 60% nitroglycerin based dynamite has been selected by CDI as the primary explosives for the ultimate elimination of the legs which are left supporting the chimney until the final demolition sequence. The approximate charge weight to be used in the elimination of the final support legs during the final demolition sequence will be less than 5 lbs per delay The final charge weight will be determined following concrete hardness tests to be made during preparation activities. CDI expects to use less than 100 lbs. of explosives for the complete operation. 10 IV ROUTING OF EXPLOSIVES CDI will coordinate delivery of explosives with Rayonier, Iconco, the Port Angeles Police and Fire Depar and the Coast Guard. Explosives will be delivered to the site by Irico Co using state approved mobile storage magazines. Delivery will be made the morning of the day when loading will commence at an hour which is comparable with the demolition schedule and agreeable to Rayonier, Iconco, and local officials. V INITIATION SYSTEM The charges placed by CDI will be detonated by a non electric system initiated from a designated command post several hundred feet away from the chimney This non electric initiation system will allow an added safety factor as the possibility of premature initiation due to extraneous electricity, thunder storms or radio frequency considerations is eliminated. The detonation circuit will be designed and assembled in accordance with guidelines suggested in The Institute of Explosives Engineers (ISEE) Blasting Handbook and by The Institute of Maker's of Explosives (LM.E.). The entire initiation system will be triple- checked by CDI prior to the detonation of preliminary and final shots. VI. LOADING PROCEDURES Beginning approximately four (4) hours before the chimney felling, explosives will be assembled and placed in CDI selected areas of the chimneys base by experienced CDI personnel in accordance with the manufacturer's recommendations anc'. guidelines established by The Institute of Maker's of Explosives (I.M.E.) All explosives charge will be checked and re- checked by CDI to ensure accurate positioning prior to the detonation. VII. ROUGH DELAY PA1'1'ERN Explosives charges will be detonated on a millisecond interval to guarantee fragmentation and structural elimination of the concrete in the legs slated for removal. This millisecond delay sequence also helps control noise and vibration. This approach virtually precludes any detonation caused damage to the adjacent structures. CDI's unique method of controlling the fall of the structure by explosives has been perfected as the result of demolition projects performed over the last 40 years. No other company or group of companies combined has access to that amount of data. This database is used to design the configuration of chimney legs to maximize safE Ly during preparation, as well as the cam hinges to guide the path of each chimney during its initial rotation and fall. 11 VIII. SEISMIC MONITORING Seismographs will be positioned by CDI to record ground motion and air pressure generated by its explosives and demolition activities. Due to the small amount of explosives detonated in delay sequence, CDI anticipates that air overpressure readings will be well within the safe zone as it relates to Federal guidelines. Historically, CDI has found that the ground impact of structures similar to the subject chimney produced ground vibration less than 1/2 of the magnitude which is considered to be an acceptable level for safe blasting in industrial areas. In conclusion, CDI's database, the design of the chimney and condition at the site indicate that adjacent improvements will not be affected by CDI's explosives demolition of the chimney structure. IX. ADJACENT PROPERTY PROTECTION CDI will contain any debris displaced by the detonation of explosives at the base of the chimney by use of layers of 9 -gauge chain link fence and Nicolon S8000 geotextile fabric. If determined necessary, Iconco shall construct berms of select material that will be placed in the fall area to dampen vibration from the impact of the chimney X. SITE SECURITY Approximately 'three (3) hours before the demolition, a safety perimeter will be established. This safety perimeter will be cordoned off to prevent access by unauthorized personnel. Any activities undertaken outside of this perimeter will have no effect on the safety of CDI operations. Demolition activities will be coordinated with the Coast Guard and the Port Angeles Police Department and Fire Department. The countdown (to be established) will start 1/2 hour before the demolition. CDI will maintain radio communications with Rayonier and Iconco personnel, plant security and other key authorities during this time. CDI will detonate explosives at the command post several hundred feet from the chimney only after assurances have been received that the safety perimeter has been secured. Personnel without radio contact will be alerted of the impending demolition by the use of auditory signals to be established. After the chimney is down, CDI will promptly survey the area, notify Rayonier and Iconco representatives and other interested parties of the situation at hand. An auditory "all clear" will be sounded from the command post indicating the security perimeter can be pulled into a smaller, pre- determined line within the Mill boundary 12 XI. SITE CONDITIONS AFTER THE EXPLOSIVES DEMOLITION Generally, the chimney is expected to impact the ground within 5 5 seconds after the initiation of explo in the final demolition sequence. The top 2/3 of the chimney is expected to flatten out while the bottom 1/3 is expected to gradually taper from a flattened state, to a basically round configuration where the chimney was cut off immediately from the base. This lower section will require further mechanical demolition during debris removal operations. Dust generated from both the detonation of the explosives and the impact of the structure at grade is an unpreventable by- product of the demolition. It will prevail in the immediate vicinity of the implosion site for a period of 2 to 5 minutes depending on weather conditions and wind speed at the time. 5A.4 DRAWINGS PLEASE SEE ATTACHED 13 0 .O75I .0.417.7 4N1 %v01 /d01 j O•I tf; 11N940,9/ (9) .r f I 'lWdO "wry," 099NY7a►410,7/ N1041 1014447,' 701/NO7 0107010 AO NODI y .1... .o,0+wnlr0 990771.040 w 70.7 oO,b %�7 7fi/ x7 I:( 010t so 19Y77/AD 1 027 darn, 00 d01 11107• 001 01 /101 Aus•w 12/470 9w/77 JJfdVt NJ/M 170007 M711ND /rYJS 1N/ I V 1 a V p ,O ;F'l /f1JYJV2N /,O,F :Ilv 2 9:3SI®1Jltd k d t1MOd f /L.t7YNr :iv 'O' a t 0- 107►+ -a Sclo11J..0 -s van11 a O; stid/1:d1Y7d:LN /,09f R c rJy 77�r(.Z/ 6I N917 ',V.1.470 Mri1 orb J NOIlt/A3 )4 1tTNOI1J3S ,071.7(+ ,0;492 d/ 9 1• ,0;997 +.411 JJ11.005 i (orid7)rAo,rPa 060 I /SF2 r� ∎011 '1 1 141 NO/lallAYd 000#41,017 I `2/ N/7 dY!

The building structure weighs approximately 1100 tons. The preliminary work by ICONCO includes, removing exterior block walls to structural frame and removing all equipment, piping, etc. from the lower 25 feet of the structure. This will allow access to structural members for explosives placements. ICONCO will then come in and prepare the building to be felled by explosives. Once the structure is prepared, CDI will arrive on site and commence loading of explosives. ICONCO will assist CDI in placing explosive charges, coordination between all parties and providing site security 5B.2 DUST CONTROL The release of dust on this project is minimized by wetting the structures and landing area. The day before the demolition, we will cut the openings in the waterwall of the boiler near the top Fire hoses will be placed in these new openings and wet down the inside of the boiler The landing area will be wetted in a similar fashion. The ground will be soaked starting the day prior to the demolition. 14 1 1 1 5B.3 CDI WORK PL.NN CONTROLLED DEMOLITION, INC 2737 MERRYMA V'S MILL ROAD PHOENIX MARYLAND 21131 USA PLAN PROCEDURE FOR THE DEMOLITION OF THE RAYON -ER IECOVEIY BOILER AND BOLE_ZHOUSE LOCATED IN PORT ANGELES, WASHINGTON FOR ICONCO 5409 OHIO AVENUE SOUTH SEATTLE, WA 98134 15 I. PROCEDURE The basic procedure to be followed in the explosives dismantling of the structure will be the placement of linear shaped charges on key structural supporting columns at the ground and 2 level of the structure. These specialized steel- cutting charges will be detonated sequentially, thereby removing column sections. This sequential elimination of key structural supports will allow CDI to utilize the weight and construction of this structure to allow it to incline in a southerly direction and fall into a pre determined open area. II. PREPARATION FOR EXPLOSIVES OPERATIONS General procedures to be used in preparation for explosives placement are as follows: A. Low -rise portions of the structure will be pre- removed prior to demolition operations. B Precision torch cutting of selected structural columns will be performed to facilitate subsequent placement of CDI's linear shaped cutting charges (see attached drawing) C. Perform pre-severance of selected splice plates and column sections to facilitate the processing of steel since the structure is on the ground. D Conveyer belting and other materials will be placed over steel- cutting charges mounted on selected columns to prevent displaced material from leaving the building's periphery explosives detonation. III. EXPLOSIVES The following types and approximate quantities of explosives will be used. A. Copper clad linear shaped charges (600 and 2,000 grain per foot) which are manufactured by Accurate Energetic Systems of McEwen, Tennessee, or their technical equivalent, will be used as the primary steel- cutting charge. Net weight of RDX explosives is approximately 52 pounds. B 55 ICI brand Exel 1 /2 second, non electric detonators of various delays will be used to initiate the charges. Connectors will be used to keep the maximum weight of explosives to 7 71bs. per delay C. Approximately 18 lbs. of Powerditch 1000 ammonium nitrate manufactured by ICI will be utilized. This explosive will be used to displace structural columns after severance by steel cutting explosives charges. IV EXPLOSIVES LOADING PROCEDURES The day prior to blasting operations, explosives will be delivered to the site. All 16 explosives transportatio_ will be coordinated with the Port Angeles Police Department and will be conducted according to local, state and federal regulations. The same morning, a test blast will be conducted with 900 and 2,00 grain per foot linear shaped charges to determine the charge performance on site specific steel columns. Following an analysis of test blast results, production explosives loading will commence. It should be noted that all "hot work" activities or other potential hazard areas of preparation will be completed prior to the introduction of explosives on site, or limited to a 50 -ft distance away from explosives as established by QSHA guidelines. As soon as explosives arrive on site, explosives signage will be posted at the plant gate. While explosives are on site, they will be stored in approved, barricaded magazines and during non working hours, Plant Security will monitor the site. While explosives are or site, weather conditions will be monitored by CDI personnel. V INITIATION SYSTEM The explosives charges placed by CDI will be detonated by a redundant, non electric blasting system. The use of this non electric system is much safer as there are no radio frequency or extraneous electricity hazards. All systems will be designed and assembled in accordance with guidelines suggested by the manufacturer and the IME. The entire system will be double checked by CDI prior to demolition operations. Initiation of charges will be completed by using a single electric blasting cap attached to the trunk line system ten (10) minutes prior to the demolition. Circuitry will be checked utilizing a Safety Devices, Inc. digital ohmmeter and verified by the blaster The electric blasting cap will be initiated with an REO CD (capacitor discharge) 600 blasting machine. VI. PROTECTION The linear shaped charges that will be utilized on this project produce very little displaced material. Conveyor belting will be placed around charges to insure that material will not leave the building's periphery during explosives charge initiation. It is anticipated that a minimal amount of dust and debris will be generated from the demolition as only the structural steel framework will be blasted. In demolition operations, most dust is generated by masonry material, most of which would be pre removed from the structure. VII. SITE SECURITY Preliminary meetings vill be conducted with Iconco and Rayonier personnel and the 17 appropriate municipal authorities to determine the extent of pedestrian, vehicular and marine traffic control during explosives demolition operations. Explosives demolition operations offer the minimal amount of disruption to ongoing operations in the Plant. It is anticipated that actual blasting operations will take place early on a Friday morning when on -site activities are at a minimum. Approximately 1/2 hour prior to demolition, a pre determined safety perimeter will be established by Iconco and CDI personnel in coordination with contractors involved. Countdown will start ten minutes prior to demolition. Radio communications with authorized personnel du this time will be maintained and the IME radio frequency and radio hazard distance recommendations will be adhered to during the electric initiation phase of the Project. Explosives will be detonated from a command post located approximately 400 -ft away from the structure only after assurances have been received that a safe perimeter had been secured. Personnel without radio contact will be alerted of the impended demolition by the use df auditory signals. Within minutes after the structure is on the ground, CDI will promptly survey the area and notify proper authorities when the area is clear VIII. SITE CONDITIONS AFTER THE IMPLOSION CDI intends to fell the structure in a southerly direction. After the charges are detonated, the structure will impact within seven (7) seconds. We anticipate that the entire structure will collapse with the highest structural member being less than 40 -ft off the ground and being well within the reach of hydraulic shears mounted on excavators. 18 5B.4 DRAWINGS PLEASE SEE ATTACHED 5C ANTICIPATED SEISMIC REACTIONS SEISMIC MONITORING LOCATIONS We anticipate generating a peak particle velocity of .8 inches per second 150 feet from the base of the chimney the U.S. Bureau of Mines has established a threshold of 2" per second.

The competent person shall also be responsible for the identification of any potentially hazardous /toxic conditions, such as lead paint or explosives, combustibles, or reactive materials in lines or tanks. PPE In addition to the minimum PPE required on all demolition projects, the torch cutter shall wear, as a minimum, the following: 1 Leather gloves 2. Burning shield or goggles 3 Fire retardant clothing 4. Respirator (see Lead Program and Respirator Protection Program) Additional Equipment In addition to the additional PPE, a charged water hose and /or an ABC fire extinguisher shall be at the work area. Safety and Health Risk Assessment 1 Safety risks associated with the torch cutting are: A. Internal fire from torch B Fires C. Explosions D Flashback E. Burns from slag or sparks 23 YOUR TTENTION PLEASE (Owner), (General Contractor), and Controlled Demolition, Inc. (QDI Implosion Subcontractor) of Phoenix, Maryland would like you to be aware that on I the of 1998 at AM, the will be demolished by implosion. Implosion is a process where a small amount of explosives is used to disrupt selected supports in a building. This allows gravity to pull the structure down in a controlled manner CDI has used this implosion method thousands of times around the world during the past 40 years to remove unwanted structures' CDI's safety record is perfect. There are three (3) points we would like to make you aware of: 1 Dust is an unpreventable byproduct of all types of demolition. With a wrecking ball, the building is slowly broken up releasing dust over several months. With implosion, the same overall quantity of dust is released over several seconds, and may linger in the gerieral area for 4 to 6 minutes. Depending on wind speed and direction on the day of the implosion, the dust may or may not reach your properties. As a precautionary measure, we recommend that you see that all windows, doors anti air intakes are closed, and cover any other openings that might allow dust to enter your apartment, house or building. We also recommend that you turn off all exhaust fans before or at the time of the implosion as these might draw air m to your building through cracks in walls and windows. 2. Early the Police Department will set up a Safety Zone aroun the buildings. This is to prevent people from getting too close. We need your cooperation with the Police to make sure that this is a safe job For those persons inside the Safety Zone, we ask that you cooperate with the Police Department and contractors. Everything they say to you or ask of you is to minimize inconvenience or to promote safety 3 The City of and Controlled Demolition, Inc. would like to advise you that there will be heavy dust in the block immediately surrounding the demolition site. Dust may also prevail outside and downwind of the safety zone, depending on weather conditions. If you find dust uncomfortable or irritating, or if you have aiy respiratory conditions that would be aggravated by dust, please stay indoors during the demolition. Should you have any questions, you should direct them to F Crushing, impact injury from falling metal after it is cut G Accidents involving gas cylinders 2. Health risks associated with the cutting torch are: A. Inhalation of fumes, smoke, cadmium, or lead B Reduction of oxygen content in confined spaces C. Heat stress Preventive Measures 1 Never cut into a closed system. All tanks and pipes must have an opening to prevent the accumulation of built -up pressure caused from the heat. The system can be opened by unbolting, drilling holes, or by cold cutting. 2. Watch where sparks are blown. Sparks can travel a long way, find a nest, and start to burn after quitting time. At the end of each shift, all cutting areas will be inspected and saturated with water if necessary A spark or piece of hot slag can burn for hours and not be noticed. Any time burning occurs near tar paper or wood, the area must be wetted prior to "calling it a day" Cutting operations will be shut down at least 30 minutes before the end of a work shift. This will allow ample time for fire watches to insure that all areas where cutting and burning have taken place are secured. All combustibles shall be moved to at least 35' away from the work cutting area. 3 All hot work areas shall always be accompanied by a water and chemical fire extinguisher 4. Always check for the presence of hydrocarbons. The pipe tank or vessel must be checked for explosive gases by an approved, calibrated instrument such as an explosimeter or equivalent. The allowable concentration of explosive gases is 0 5 Always keep the torch maintained. Do not allow the tip of the torch to become clogged. Remove and clean or replace any torch tip that becomes clogged. Keep the torch tip away from running slag; it can cause the torch to clog up, resulting in a flashback. 6 Often people get in a hurry or become lazy and don't respect the limitations of their torch. The torch is not A. a cigarette lighter 24 B. a pry -ba C. a mallet or sledge hammer D a flashlight E. intrinsically safe. 25 7 Although all tanks and gauges are equipped with back flow preventors, they must not be abused or mistreated in any way 8. Workers shall 'wear leather gloves and fire retardant coveralls when torch cutting to prevent sparks /slag from contacting flammable clothing or skin. 9 Workers should position themselves away from sparks /slag as far as is practical. 10 Workers will be provided with tinted face /eye protection. 11 When cutting a piece, the cutter is exposing him /herself to an impact injury It sounds simple, but one must not be in the way of freshly cut, hot steel. 12. Valve protection caps shall be in place at all times when cylinders are not in use. Regulators and gauges shall be removed and valve protection caps put in place before moving cylinders, unless they are secured on special equipment made for this purpose. A. Cylinders shall be placed out of the way of sparks, hot slag, falling debris, and electrical current. B Cylinders, when moved by hand, should be tilted and rolled on the bottom ledge. If carrying is necessary, two people should be used. C. Oxy /acetylene bottles and propane bottles shall not be stored within 20' of each other D Fuel gas cylinder will be stored in a designated area. Cylinders shall be stored in an upright position with valve protection caps in place. Cylinders will be secured in place to prevent them from being accidentally knocked over Storage of cylinders shall comply with OSHA 1926.350 Empty cylinders shall be removed from the work area at the end of the shift. 13 Torch cutti shall not be performed on wood, synthetic material, rubber lined pipe and vessels. Process piping, tanks and equipment associated with the HF, ammoni-3 disassociation, hydrogen distribution, and propane systems shall be checked prior to cutting. 14. All ventilation systems (natural or portable) have limitations. A condition may occur in which fumes from a torch or several torches overloads the capacity of the ventilation system. A. Inside the buildings, Red Baron HEPA machines can be used as localized exhaust to minimize worker exposure to smoke, fumes, cadmium, and lead. The intake of the localized ventilation will be positioned within 2' -3' of the area being cut and at the same elevation. Localized ventilation ductwork will be inspected and maintained as necessary 15 Torch cutting work areas that involve lead and cadmium will be demarcated with warning tape, and the work area will be posted with warning signs. The wording of the signs will be in accordance with ICONCO's compliance program. 16 Burning rigs s Mall be broken down at the end of each shift. Fuel gas hoses shall be stored in a ventilated area (never in closed gang boxes) 17 Air will be monitored for oxygen content and excessive concentrations of harmful gases. Should oxygen levels or harmful gas concentration levels fall outside acceptable limits, work will be stopped and workers moved to another location until condtions are brought back to acceptable levels. 18. Results of interior monitoring of pipes, tanks, etc., for. flammable, explosive atmosphere, RAD product, HF, or AHF will be performed prior to comencemeni of torch cutting. 19 Workers will drink plenty of fluids. 20. Insure that ivorkers are made available for heat stress monitoring by the Competent ?erson on a routine basis when conditions warrant such monitoring. Project: Stack Recover Bldg.
