Saturday 11AM Storm Update Hurricane Harvey made landfall Friday evening near Port Aransas, Texas. Harvey has been downgraded to a category 1 storm with 75 MPH sustained winds with 90 MPH gusts. The system tracked further inland than what was originally forecasted, which in turn changed the expected track to west of the Houston area. We are still forecasted to receive 18 to 24 inches of rainfall through mid-week. The Crosby facility is currently in Phase 3 of our Hurricane Preparedness Plan, production has ceased in the units and they are stabilized. We have taken action to divert most of the rainwater from entering the Waste Water Treatment Plant to prevent overwhelming the system. The storm ride out crew will be activated during the day today, the main driver for implementation of the ride out crew is expected lack of access to the site due to significant flooding. I will keep the site informed of changing conditions via Send Word Now, as well as provide a daily update on conditions to the BU Management Team. We have begun to experience minor flooding on site, and storm water ditches on the outside perimeter of the site are very near over-topping. Attached are some photos of minor flooding on the site. • • • • • • • • • No current people issues, everyone was able to report to work this morning. Batch and Continuous units have been idled and cleared. Backup generators and refrigerated trailers have been topped off with diesel, and arrangements have been made to acquire a backup supply of fuel to be stored on site, nitrogen skid was serviced and topped off. There are no current site accessibility issues, but storm water ditches in the area are very full. Steady rain for much of the morning, with heavy rain in the storm bands, but no significant localized flooding issues to report as of yet, significant flooding is expected in the general area over the next several days, and several locations on the site are prone to flooding, actions have been taken to minimize the potential impact of flooded areas. Many roadways in the greater Houston area have incurred flooding and we have a list of current road closures (map attached below- thanks Janet). No environmental impact to report, guidance was issued to the shift supervisors for reporting any incident which has off-site impact. We are still awaiting our back up supply delivery of diesel, we have contacted the vendor and are awaiting a response. We will re-evaluate the return to normal staffing on a daily basis. ARK_EPA_0000451 Saturday 7 6 PM Just an --the Crosby phone lines are down' we are not able to call out, or receive outside calls, it you need to reach the plant' please use the followmg mobile numbers: Sunday 9:37 AM It's been a long, tough night at the Crosby Tropical Storm Harvey spent most of Saturday night practically stalled, dumping double digit rainrall totals all over the region (we received an excess of 20 inches in the past 24 hours), Harvey is movmg toward the south southwest near 1 mph, and a slow southeastward to eastasoutheastward motion is expected over the next couple of days. On the forecast track' the center will remain inland or move very near the coast ol southeastern Texas through Monday. Harvey ls expected to produce additional rain accumulations of 15 to 25 inches over the and upper Texas coast through Thursday Isolated storm totals may reach around 40 inches in this area Rainfall at this magnitude cause catastrophic and lite-threatening rlooding Much or the Crosby site surrered during the night we had to take actions to sandbag a dike wall in the Waste Water Treatment Plant and move cold storage product (Lup11M75 to building a) before electrical circuie tor a refrigeration unit were exposed to rising water (building 3i Retrigeration compressors and control power have been disconnected. Transformers for 5 (chlorine inyection for lresh water) and the water well pump had to be raised to prevent submersion Loss of phone service for the plants This also shut down the Pl server for MPU. This requires us to take manual readings (or all environmental data at 1 hour intervals and to retrieve treezer building temperatures locally This puts all of us out in the weather more frequently Rainwater is not separated from process wastewater putting an incredible strain on well operations The increased injection rates means the loss of filtration at a higher rate. The preacoating of diatomaceous earth has to be washed out arid applied once or twice in a 24 hr period and is done out in the elements Under normal operation the pre-coating (or turning the filter around in WVVT Jargon) is only needed once every 4 days The well operator has about 7 surnps to keep up with, each with a backup diaphragm pump that has to be started and monitored. Roads inside the plant are currently impassable Without trucks -- and some areas are completely impassable As the water began to accumulate, operations discovered several underground leaks on our nitrogen header to the piante those leaking areas have been flagged forfollowaup We have also ran across a snake in the flood waters I Will continue to keep site personnel informed oi changing conditions via Send Word Now' as well as provide a daily update on conditions to the EU Management Team Storm water ditches on the outside perimeter ol the site are the roadways around the racility We are now experiencing another torrential downpour as i write this communication - No current people issues, the ride out crew was able to report to work on Saturday afternoon - Batch and Continuous have been ldled and cleared . Monitoring ail sump levels and tank containments. . High levels in sanitary surnps has resulted in the restriclion of the use of bathroom facilities • • • • • • Backup generators and refrigerated trailers have been topped off with diesel, our shipment of the backup supply of diesel arrived on site Saturday afternoon. There is significant flooding in the greater Houston area and Harris county, many roads are closed, and many local communities were affected by catastrophic flooding overnight. Heavy rain for the majority of the night on site, we are experiencing moderate flooding across the site. Many roadways in the greater Houston area have incurred flooding and we have a list of current road closures. No environmental impact to report, guidance was issued to the shift supervisors for reporting any incident which has off-site impact. We will re-evaluate the return to normal staffing on a daily basis -this appears to be a long term deployment for the ride out crew. Sunday-4:39PM The Crosby site continued to receive heavy rain for most of the day today. We now only have only 1 freezer building remaining on electrical power (building 27). The remaining freezer buildings have had their electrical power supply and or cooling units inundated with flood waters. We have low temperature products stored in refers and chill cabinets & building 27. We have set up the liquid nitrogen back up system just in case we lose power to the site. The nitrogen lines were under water, so we had to break the lines to blow out water to prevent immediate freezing when put in service. Which brings me to another issue of concern, the main power transformers for the site are about a foot or so from taking on water (see attached picture). This could cause a site wide power outage and require the use of backup nitrogen and moving the product from the chill cabinets to a spare refer. We have no intemet/intranet access at the site, and we are relying on cell phones for our only communication means. We have also started a list of potentially damaged equipment and other costs associated with this event. This effort of our ride out crew has been nothing short of heroic. We are keeping safety in the forefront at all times, working outside using the buddy system, and not taking unnecessary risks. ARK_EPA_0000454 Monday-4:17AM Another difficult night for the Crosby team, we received more heavy rain and a significant increase in site water levels. We began taking on water in MCC 39, we cut the power which resulted in the loss of all power to the Waste Water Treatment Plant and Wells. Carolyn Hervey was notified of the potential to overflow waste water to the containment dike (this has not yet happened). We also lost power to the radio repeater and the radios were out of service until we hooked up our portable generator to supply power to the repeater. Building 16 (CPU) began taking on water, cut power to the building (it now has over a foot of standing water. Cut power to building 10 due to water reaching 480V transformer. With the flood waters getting very close to the site main power transformers, we decided to move all low temperature products to reefers. At approximately 2AM when began blowing transformers and lost all site power. 32GN-1 (building 29 backup generator) failed- generator appears to have been inundated with water. Currently in the process of moving all low temp material from building 27 to reefers (building still up on generator power). Building 21 is also up on generator power. Once water recedes, we will have do a complete site wide damage assessment, we have countless pieces of equipment, electrical circuits, cooling units, etc. under water. We currently have a break in the rain, but the water is continuing to rise. We are just beginning to take on water in building 29. Also- some of our ride ARK_EPA_0000455 out team members have received water damage to their vehicles. Reefers - We have 3 empties on site, 2 will not run, and we can't use the other due to its position. We have 2 yard mules on site that have both been stranded in high water. We still have low temp product in building 27. Monday-2:50PM The generator providing power to B21 & B27 has been inundated with water and has shutdown. All of the 223 S has been moved to a reefer. Monday-9:00PM Moved 48 pallets of cold temperature product from B27 to a reefer. We had to break down each pallet and hand stacked all containers into the reefer to accommodate all of the material -this process took approximately 5 hours. While loading the reefer, we lost cooling capacity on one of our reefers in the laydown area. Once we completed the off-loading ofB27, we noticed that we lost cooling on reefer #7. Consulted with the Crisis Team and decided to move from B21 back to B4, when moving to B4, noticed that we lost cooling on reefer #8. Tuesday - 7AM Water rose overnight, now have 6" of water in B4. Consulted with Crisis Team and determined that it was time to arrange extraction. Completed site assessment: • Water now up to the bottom of reefers #6, 7, and 8. • Reefer #6 was moved by water (see photo below) • WWT plant main dike at 2A & 2B were breached by flood water from outside of the dike, level equalized at approximately 8:15AM Reefer near B21 moved by water ARK_EPA_0000456 Water breaching the railroad track, which will stop the level increase on site. Water flow on site increased greatly when this happened. Planned to make a reconnaissance trip to get trailer numbers, but the rescue team arrived and would not allow us to check the trailers.
