Time Details
0700 SES and Coastwide arrived on site. SES project manager, Mitch Edwards met with site technician, Mark Stockwell to review the scope of work and tour the site. Coastwide’s supervisor, Ben Cardenas and 3 crewmen began mobilizing equipment.
0710 CUSD representative, Travis Kirk arrived on site and reviewed the scope of work and utilities status and unlock the buildings.
0720 SES toured the project site with Ben Cardenas and reviewed the scope of work for asbestos abatement, lead paint removal and stabilization, and other hazardous materials within the scope of work. SES also discussed the clearance inspection methods with Coastwide. 0800 Coastwide began installing polyethylene drop sheeting along the base of the exterior walls of the shop and southeast out buildings in preparation for lead paint removal and stabilization from the exterior walls, eaves and fascia.
0830 SES finished reviewing Coastwide’s worker certifications and medical release information. SES discovered that 1 of Coastwide’s workers was not certified to do lead work, Omar Yanez. Ben Cardenas was informed, and he pulled Omar from the lead crew and had him begin preparation work inside the house for pending asbestos abatement work. SES provided a preparation inspection of the Zone 1 preparation measures and approved the work area, authorizing Coastwide to continue paint removal and stabilization.
0840 Ben Cardenas informed SES that a rental generator would be arriving later this morning to run the negative air machines and other equipment once asbestos abatement begins. He also stated that his DOP testing firm was arriving this morning to test the negative air machines and HEPA vacuums. 0900 Coastwide started preparing the Zone 2 – northeast utility room, restroom and garage hallway, and Zone 3 - basement and crawlspace, for upcoming asbestos abatement work. According to Ben Cardenas, this work won’t begin until tomorrow or Wednesday. SES PM offsite. 0915 Envirostar’s representative, Ed, arrived on site to DOP test the HEPA filtration machinery. Coastwide has not yet received their generator so the testing will need to wait until it arrives. 0915 SES left the jobsite to obtain site keys from the CUSD maintenance office. 1000 Envirostar left the jobsite. They will return tomorrow morning to DOP test once a generator is obtained to operate the HEPA filtration machinery.
1100 Coastwide broke for lunch.
1130 Coastwide’s power generator arrived on site, delivered by the rental company. 1200 Coastwide’s crewmen returned from lunch. Two workers continued lead paint removal/stabilization on shop and southeast buildings while Ben Cardenas and 1 other worker continued preparation work in the house.
1220 Ben Cardenas opened the main water valves to the building after cutting a zip tie that secured the water main at the street.
1240 Ben Cardenas and 1 other worker removed the mercury containing thermostats located in the house.

The thermostats will be wrapped in polyethylene sheeting and disposed of as mercury containing waste.
1315 Coastwide’s lead paint removal crewmen finished scraping the chipping and peeling paint from the southeast shop and outbuildings. The crewmen relocated the work area to the central shed where they placed polyethylene sheeting on the ground around the building perimeter and prepared to begin paint stabilization. SES began a preliminary visual clearance inspection of the shop and southeast outbuildings. The paint removal/stabilization work appeared to have been completed as required, however, the remaining painted surfaces were found to be badly chalking and SES informed Ben Cardenas that the re-priming would not likely adhere to the exterior paint surfaces. SES recommended that Coastwide bring rags to the jobsite and wet wipe the exterior paint before stabilization priming. He stated that he would do so tomorrow. SES will complete a final visual inspection of Zone 1 – exterior paint removal once the wet wiping is completed, and before the priming is started. 1330 Coastwide finished establishing the regulate work area around the central shed and SES completed a preparation inspection before authorizing the crewmen to continue paint removal/stabilization on the building.
1400 SES walked the perimeter of the house with Ben Cardenas to inspect for damaged painted surfaces that would require paint stabilization scraping. Minor quantities of damaged paint were identified, mostly on the flower box framing below the windows, some eaves and portico framing, and on various window framing around the building. Coastwide will finalize the paint stabilization on house tomorrow. 1410 Ben Cardenas was instructed to turn off the water to the site and secure all doors before leaving at the end of each day. Coastwide will also secure its equipment inside the building each night.

Time Details
0600 SES and Coastwide arrived on site. Two of the lead workers began setting up equipment to continue lead paint removal around the perimeter of the house. Ben Cardenas and the 4th worker staged HEPA equipment for DOP testing.
0610 Envirostar arrived on site and began DOP testing Coastwide’s HEPA equipment (3 air filtration machines, 2 vacuums and 2 air scrubbers). All equipment passed the DOP testing and certification stickers were attached to each machine.
0615 Coastwide’s supervisor, Ben Cardenas, walked the perimeter of the house with his 2 lead workers and SES and denoted areas where damaged paint was located on window box shelves, window frames, portico columns and walls. SES also directed Coastwide to remove damaged paint from concrete sidewalks.
0715 Coastwide finished preparation measures for Zone 2 – the northeast containment of the house at the utility room, restroom and garage hallway. SES completed a preparation inspection of the work area and authorized Coastwide to begin removing the AC floor tile in the work area. SES inspected the Zone 2 manometer and observed average negative pressure between -0.060 and -0.082 inches water column.
0745 Coastwide’s lead paint removal crewmen began stabilizing paint removal areas on the west side exterior perimeter of the house using an airless sprayer and primer paint. SES inspected the areas completed and confirmed that the damaged paint had been removed and stabilized appropriately. 0815 Coastwide finished the gross removal of the AC vinyl floor tile from Zone 2 and began bagging the waste and detail cleaning the floor. SES verified that the non-friable waste was double bagged in non- labeled waste bags. SES confirmed again that the analytical results for the flooring in Zone 2 (018- M28-01 & 018-M28-02) yielded 5% chrysotile asbestos in the floor tile only and the associated mastic was “non-detect” for asbestos, therefore, Coastwide will be able to leave the floor mastic in place after the tile is removed.
0920 Coastwide finished loading out waste bags from the Zone 2 containment, as well as wet wiping and HEPA vacuuming. Ben Cardenas requested a visual clearance inspection of the work area. 0930 SES entered the Zone 2 containment to complete a visual clearance inspection. SES walked the work area with Coastwide’s worker and identified several areas where 3-dimensional floor tile debris remained on the floor surface. The debris was difficult to identify due to the non-asbestos containing floor mastic remaining on the concrete floor surface. Coastwide was directed to continue cleaning with a hand scraper rather than a spud bar, then HEPA vacuum a second time before requesting another visual clearance inspection.
0955 Coastwide requested a second visual clearance inspection of the Zone 2 containment. SES entered the work area and inspected the floor with the worker. SES identified numerous areas where additional floor tile debris was located and Coastwide’s worker followed behind and cleaned the areas immediately.
1010 SES approved the Zone 2 containment and authorized Coastwide to encapsulate the work area. 1015 Coastwide’s crewmen broke for lunch.
1115 Coastwide returned from lunch and one worker continued lead paint removal and stabilization on the south and east exterior walls of the house. The second lead worker began spray paint stabilization of the central shed. A third worker and the supervisor, Ben, began preparation of the shop to remove the ceiling-mounted heater which contains asbestos insulation. 1140 Coastwide’s paint sprayer relocated to the shop and southeast outbuilding to continue spray paint stabilization of the exterior of these buildings.
1145 SES inspected the preparation efforts of the heater in the shop – Zone 4. SES observed the Coastwide worker was not wearing a respirator and suit since the ACM material was inside the heater and would not be disturbed during removal. SES recommended that the worker wear PPE as the ACM is friable and may be dislodge during removal. SES also recommended that Coastwide install a mini containment around the heater work area in order to more easily collect and pass air clearance sampling tomorrow. Ben Cardenas began installing a polyethylene curtain around the work area. 1215 Coastwide finished the wrap & cut removal of the shop heater Zone 4 and SES inspected the work area before approving the visual clearance. SES authorized Coastwide to encapsulate the work area.

Clearance samples will be collected tomorrow in the work area. 1240 Coastwide finished encapsulating the Zone 4 work area. 1300 Coastwide’s lead workers relocated. The paint scraper moved from the south and east sides of the house to the northeast corner near the garage, and the paint sprayer moved from the shop to the south and east sides of the house.

Time Details
1315 Coastwide collected all lead and asbestos debris bags and properly labeled the bags. SES asked Ben Cardenas how Coastwide intends to dispose of the lead ceramic tile waste. Ben was not aware if the ceramic tile debris would be disposed of as CA hazardous lead waste or if it would be sent in for characterization analysis. He stated that he would discuss this with his supervisor, Jose. SES requested that he obtain the information as soon as possible in order to coordinate waste disposal pickup before the end of the week. Ben state that he would get an answer tomorrow. 1330 Coastwide finished paint stabilization painting for the day and began cleaning the equipment. One lead worker continued to scrape damaged paint around the exterior of the garage. Coastwide will need to complete the remaining stabilization painting tomorrow. The remaining workers began cleaning up the jobsite and securing supplies and equipment for the night. 1350 Coastwide turned off the water main for the night. 1415 Coastwide and SES secured the doors to the property and left the jobsite.

Time Details
0600 SES and Coastwide arrived on site. Coastwide had a 3-person crew on site, one supervisor and 2 workers. The two workers began installing the remaining preparation measures in the Zone 3 work area, in order to begin abatement of AC duct wrap/tape. Ben Cardenas stated that Coastwide will use a wrap and cut removal method to complete abatement. The workers will wet the ACM duct wrap/tape, then cover the wrapped sections of ductwork in polyethylene sheeting before disconnecting the non- ACM-covered sections of ductwork. All removed sections of ductwork will be placed on polyethylene sheeting then burrito wrapped and labeled for friable disposal as RACM. 0620 Coastwide assisted SES in installing electrical to the shop and northeast section of the house in order for SES to collect non-aggressive PCM air clearance samples. 0630 SES began installing air testing pumps in the Zones 2 and 4 work areas. 0640 SES entered the Zone 2 work area and installed one pump inside the containment and one pump outside.
0646 SES started 2 non-aggressive PCM air clearance samples in Zone 4. One sample was collected inside the mini containment and a second was collected outside the containment barrier yet inside the shop. 0655 SES completed a pre-abatement inspection of the Zone 3 work area. Coastwide had installed all of its critical barriers and a one stage decontamination chamber. SES inspected Coastwide’s manometer and observed that negative pressure inside the work area was averaging -0.04 inches water column.

SES authorized Coastwide to begin abatement in Zone 4.
0700 Coastwide’s two abatement workers entered the Zone 4 containment to begin abatement. 0730 Coastwide’s supervisor, Ben Cardenas, continued preparations in the house restrooms and kitchen to ready the work areas for removal of the lead containing ceramic tile. He also continued removing various appliances in the kitchen of the house for disposal. 0840 SES completed a calibration check on the clearance samples being collected in Zones 2 and 4 and found that the pumps were running at the same flow rates. 0856 SES retrieved the air samples collected in Zone 2 – northeast restroom, utility rooms and garage hallway.
0902 SES retrieved the air samples collected in Zone 4 – shop mini-containment at the ceiling mounted heater unit.
0915 Ben Cardenas requested a preparation inspection of the kitchen work area in order to begin removing the lead containing ceramic tile from the counter tops. SES directed Coastwide to cover floor and various surfaces with polyethylene sheeting to minimize the cleanup efforts. Coastwide was also directed to place “lead hazard” signage on the doorways to the kitchen before starting the removal work.
0930 Ben Cardenas informed SES that his crewmen in the basement had discovered a transite pipe leading from the basement up through the house. SES and Ben Cardenas accessed the roof and opened a plaster wall in the dining room of the house to determine the exact location of the pipe. A 10-inch diameter asbestos cement pipe was revealed inside the wall. SES and Coastwide estimated that the pipe is approximately 12 feet long. SES recommended that Coastwide install a mini-containment inside the dining room since the pipe is too heavy and too long to remove intact without breaking it into sections. Alternatively, Coastwide was allowed to break the pipe within a glovebag; however, Ben Cardenas believed that method would be too difficult to break the pipe inside the confinement of the bag enclosure.
1000 Coastwide broke for lunch.
1010 SES left the jobsite to deliver the air clearance samples to Forensic Analytical Lab for Rush analysis. 1100 Coastwide returned from lunch and 2 workers returned to Zone 3 basement/crawlspace containment to continue removing duct wrap/tape. Ben Cardenas continued to open the access hole in the wall of the dining room to uncover the transite pipe. He also began installing a mini-containment in the dining room.
1200 SES observed that Ben Cardenas had finished installing the mini-containment in the dining room (Zone 5) and he requested a preparation inspection of the work area. SES recommended installing an asbestos sign on the work area before beginning to break the pipe into manageable sections. 1215 SES approved the containment measures for Zone 5 – transite pipe mini-containment, and Ben Cardenas donned protective equipment and began breaking the pipe. All waste was either burrito wrapped or placed in waste bags. SES observed that the transite pipe was removed intact with minimal breakage at the collar seems. A total of 2 five-foot burritos and 2 waste bags of debris were generated.

0600 SES and Coastwide arrived on site. Coastwide has a 5-person crew on site, one supervisor and 4 workers. SES informed Coastwide’s supervisor, Ben Cardenas that the containments at Zone 2 – northeast restroom, utility rooms and garage hallway, and Zone 4 – shop ceiling mounted mini- containment had both passed air clearance testing and the containment barriers could be dismantled.

One worker was assigned to take down these two containments. A second worker was assigned to continue the final cleaning effort in the basement/crawlspace of the house (Zone 3), and 2 lead workers were assigned to begin demolishing the lead glazed ceramic tile in the kitchen and restrooms (Zone 6).
0620 Coastwide’s crewmen established negative pressure in the kitchen and master bathroom and SES inspected the containments, finding them appropriate to begin lead demolition work. Containment barriers were in place, “lead hazard” signage was placed on the entrance doors to the containments and negative air pressure was observed.
0640 Coastwide’s crewmen began ceramic tile demolition on the kitchen and SES informed Ben Cardenas that if noise was noticeable in the street or the edges of the property the crewmen would have to stop the work until after 0700.
0645 SES directed Coastwide to stop the ceramic tile demolition work until after 0700. Ben Cardenas stopped the workers.
0700 Coastwide continued demolishing ceramic tile in the kitchen and master bathroom of the house. 0715 Coastwide began loading out friable asbestos waste debris bags from the Zone 3 basement containment. SES observed that the manometer for the Zone 3 containment was adequate, recording lower than -0.03 inches water column. SES observed that the bags were double wrapped, goose neck tied, and properly labeled. All debris bags had generator labels attached. SES inspected the generator labels and confirmed that the EPA ID numbers matched that used for Sedgwick Elementary School of:

CAC002964442. Also, SES obtained a copy of Coastwide’s friable ACM waste manifest and confirmed the generator’s labels matched the manifest number: 015975640 JJK. 0800 Coastwide finished loading out ACM waste bags from the Zone 3 basement containment of the house and finalized cleaning.
0810 SES rep enters Zone 3 for the final visual clearance inspection. Upon inspecting the first 3 or 4 locations SES discovered suspected duct wrap debris on the surface of the hardened dirt floor of the crawlspace. SES also observed both sheetrock and plaster debris on the soil surface under these penetrations. SES discontinued the inspection and recommended that Coastwide bring a small HEPA vacuum into the crawlspace and vacuum a 3 to 4 square foot section of the hardened soil floor surface.

Coastwide will complete this effort before requesting a second visual clearance inspection. 0850 Coastwide finished removing the lead glazed ceramic tile in the kitchen of the house and requested a visual clearance inspection. SES entered the work area and found that all ceramic tile debris had been completely removed and surfaces in the kitchen had been wet wiped appropriately. SES authorized the visual clearance of the work area and authorized Coastwide to deregulate the work area and take down the containment barriers.
0910 Coastwide’s lead crewman relocated to the south bathroom of the house and SES inspected the regulated work area prior to authorizing the crewmen to begin ceramic tile demolition. Negative pressure had been established, all doors and windows had been isolated with polyethylene sheeting and “Lead hazard” signage was in place. Coastwide started demolition. 0930 Coastwide requested a second visual clearance inspection of the Zone 3 – house basement/crawlspace containment. SES suited up again, entered the work area and began the inspection accompanied by one of Coastwide’s workers. During the inspection, SES identified areas under register vent holes in the subfloor where additional plaster and sheetrock debris was observed.

Although no additional duct insulation paper was identified, SES directed Coastwide’s worker to continue HEPA vacuuming the soil surfaces in these areas to remove questionable materials. SES accompanied the worker throughout the crawlspace and oversaw the cleanup effort. 1015 Coastwide broke for lunch.
1020 SES finished the visual clearance inspection of the Zone 3 basement/crawlspace and approved the work area. SES and Coastwide’s worker exited the work area and informed Ben Cardenas that Zone 3 had passed the visual inspection. Coastwide was authorized to encapsulate the work area. 1115 Coastwide returned from lunch. The three lead workers continued ceramic tile demolition in the master bathroom and south guest bathroom and began demolition in the north guest restroom. One worker continued removing containment barriers in the shop (Zone 4) and in the kitchen (Zone 6). Ben Cardenas and one other worker began preparing to encapsulate the Zone 3 basement and crawlspace in preparation for tomorrow morning’s non-aggressive PCM air clearance testing. 1145 Coastwide began encapsulating the Zone 3 containment.

Time Details
1230 Coastwide continued loading out lead containing debris bags consisting of lead-glazed ceramic tile and mortar from the Zone 6 work areas.
1250 SES was requested to sign the hazardous waste manifest for asbestos generated by Coastwide. The total amount of waste yielded approximately 3 cubic yards of asbestos waste consisting of ductwork, ACM duct wrap and tape, and other debris.
1310 Coastwide requested a visual clearance inspection of the master bathroom following ceramic tile demolition. The work area was found properly cleaned and SES authorized Coastwide to deregulate the work area and take down the containment barriers and turn off the negative pressure machine. 1320 Coastwide requested a visual clearance inspection of the northwest guest restroom following ceramic tile demolition. The work area was found properly cleaned and SES authorized Coastwide to deregulate the work area and take down the containment barriers and turn off the negative pressure machine.
1345 Coastwide’s supervisor, Ben Cardenas informed SES that the crew would not finish the remaining work in the Zone 6 work areas this afternoon. They still have the final cleaning effort in the southeast guest bathroom and need to start the small work area in the shower of the northeast restroom. He anticipates that the crew will need approximately 3 hours to finish the work tomorrow morning as well as loading out the remaining lead containing waste and helping SES collect the air clearance samples in Zone 3. Ben stated that Coastwide had not yet received the analytical results for the lead waste characterization sample that was collected, so he doesn’t know if the ceramic tile waste bags will be able to be disposed of as construction debris or not. His supervisor, Jose informed him that results should be known before the crew finishes tomorrow morning. 1415 Coastwide finished cleaning up the jobsite for the day and securing the site buildings. SES and Coastwide left the jobsite.

SUMMARY OF DAILY EVENTS

• Zone 3: SES collected non-aggressive PCM air clearance samples in the basement and crawlspace of the house. Results pending.

• Zone 6: Coastwide completed removal of the lead containing ceramic tile at remaining lead work areas and SES completed and passed the final visual clearance inspections. Coastwide provided analytical documentation that waste characterization analysis indicated the ceramic tile could be disposed of as regular construction debris and did not present a lead hazard. Coastwide also demobilized most equipment and supplies, although the regulated work area and containment barriers for Zone 3 remained in place pending air clearance sample analysis. If the samples fail clearance testing, SES and Coastwide will return on Monday to re-clean and re-test.

Time Details
0600 SES and Coastwide arrived on site. Coastwide has a 3-person crew on site, one supervisor and 2 lead trained workers. Coastwide began the final cleaning process in the southwest guest bathroom and began lead ceramic tile demolition in the northeast guest restroom. 0615 SES began setting up air sampling pumps to collect non-aggressive PCM air clearance samples in the basement and crawlspace of the house (Zone 3).
0630 Ben Cardenas provided SES with the analytical results for the wastes characterization sample that was collected of the ceramic tile debris collected from the kitchen and restrooms of the house. The result indicated that the ceramic tile can be disposed of as construction debris, therefore, Coastwide will not need to transport and dispose of the material with a waste manifest. Ben also provided SES with a lead waste manifest for the small amount of lead chip waste collected from the scraping of the exterior surfaces of the site buildings. This waste will be disposed of as hazardous waste as it is assumed to exceed the limit for disposal. A total of 2 bags of lead paint chips totaling approximately 12 pounds will be disposed of.
0705 SES entered the Zone 3 basement containment and set up air sampling pumps. 0719 SES started the air clearance samples in Zone 3.
0805 Coastwide requested a visual clearance inspection of the southwest guest bathroom in Zone 6. SES inspected the work area and found it properly cleaned. SES authorized Coastwide to deregulate and remove the containment.
0820 SES entered the Zone 3 containment to complete a mid-run calibration check. All pumps were running as originally calibrated.
0830 Coastwide requested a visual clearance inspection of the final Zone 6 work area in the northeast guest restroom near the garage. SES inspected the work area and approved the ceramic tile removal.

Coastwide was authorized to deregulate and remove the containment barriers. 0840 Coastwide began a final cleaning of the jobsite, retrieving equipment and supplies and loading its truck.
0915 Coastwide’s non-hazardous waste bin arrived on site. Ben agreed to wait for approximately15 minutes until the samples in Zone 3 were retrieved before Coastwide started loading out bags of ceramic tile. 0920 SES entered the Zone 3 basement containment to post calibrate the sampling pumps and retrieve the air sample cassettes.
0930 Coastwide started loading out its non-hazardous waste and demobilizing remaining supplies and equipment.
1030 Coastwide and SES secured the buildings and left the jobsite.
