Dear Blog Reader,
Since all of us at the Holly Plant are observing a winter holiday from 12/21 – 1/3/2013, we wanted to extend to you my very best wishes for a restful, relaxing, and joyous Holiday Season. May it be filled with well wishes and be a time to reflect on all you’ve accomplished in 2012. Whether this week is business as usual for you, or spent around the table with friends and family, all of us at the Holly Decommissioning Project are thinking about you and yours.
Secondly, we wanted to thank you for your readership and patience with the Holly Plant Decommissioning Project. With another year behind us, we bring you the Holly Plant 2012 wrap up! As you can see, the team has made significant progress in the past 12 months.
January – The project couldn’t achieve its current status without the Haul Road.
As mentioned earlier, the trail has not been detoured and remains in place as is until demolition is completed. All hikers and bikers please use caution when approaching the haul road connecting Cesar Chavez and the Holly Plant.
February – The team started on the Abatement and Decontamination phase of the project.
The highly trained team started the asbestos removal work and used the yellow steel containers to contain the asbestos.
March – This month’s highlight was finishing the Metz Parking lot.
While some of the team has been hard at work inside the plant, we would like to highlight the hard work done by some of our team members. We finished paving the Metz Recreation Center Parking Lot. This parking accommodates all the cars currently parking on Pedernales. Pedernales is strictly a haul road and entrance for team members to get to work in the morning at the Holly Plant.
April – Divers were onsite to perform an inspection of the water lines.
You may have not known there are water lines that run from Holly to Ladybird Lake. As part of the decommissioning of the Holly Plant, we needed to inspect the seals. This is very important.
May – The team highlight was the removal of the 40ft traveling water screens.
This was a job well done by TRC, LVI, and Austin Energy. The traveling water screens were recycled.
June – The team started to remove the steel and removed most of the asbestos from Holly 1.
Holly 1 is now asbestos free. The team has finally finished removing all the asbestos for this portion of the abatement and decontamination phase.
July – The crane became operational and the team began removing the boilers.
The team began using the crane to disassemble Holly 1. On July 20, 2012, the Holly Plant Decommissioning Project team welcomed local media as well as Mike Martinez, City of Austin Council Member, for a photo opportunity of the crane.
August – The team began to remove Boiler 1 from the bottom to the top.
The joint Austin Energy, TRC, and LVI team dismantled and removed the bottom third of the Holly Unit 1 Boiler. First, the team cut the bottom tube panels. Next, the internals are cut and dropped out of Holly boiler #1. Lastly, the team removes the spaghetti tubing, which is the superheating and reheating section of the boiler.
September – The team is working on removing several sections of the plant at once. However, we would like to highlight the demolition team’s accomplishment in removing the Holly 2 turbine.
The joint Austin Energy, TRC, and LVI team completely removed and sent to recycling the entire steam turbine composed of the low pressure, intermediate and high pressure sections.
October – The TRC, LVI, and Austin Energy team has started demolition and completed most of the asbestos abatement work on Holly Unit 3.
The team removed the Holly Unit 3 feedwater heaters.
November – The demolition team removed the last water tank.
The tank held one million gallons of water.
December – The TRC, LVI, and Austin Energy team started to remove the Holly Unit 4 boiler.
The joint team initially cut the bottom of the boiler and worked upwards removing all four walls as they go to the top. The pieces that are cut are allowed to drop onto a 3 foot layer of soft soil. The soil is used to dampen the vibration that is created by the falling pieces.
We won’t be posting our regularly scheduled Friday blog post next week. Please visit us in the 2013 to read the latest news about our current project status.
Austin Energy, TRC, LVI and all of the Holly Decommissioning Team
Here is your regular scheduled update from the Holly Plant Decommissioning Project Team:
The TRC, LVI, and Austin Energy team has completed the asbestos abatement work on Holly Unit 3 and started demolition. This week’s post details removing the Holly Unit 3 feedwater heaters.
Workers are removing the plastic wind barrier from the outside of Holly 3. The asbestos abatement is complete and Holly Unit 3 can be exposed to the environment.
Heaters are composed of hundreds of tubes where water is circulated inside the tubes and heated by auxiliary steam residing outside the tubes. The water is pumped to a boiler to be heated at a higher temperature until it is converted to primary steam for use by the steam turbine. This image illustrates the front view of the three feed water heaters that are on the ground floor.
The workers have cut and pulled the middle heater.
The excavator drags the middle feed water heater along the ground to the chopping and removal work area.
The heater rests on its side waiting to be cut and removed.
After cutting the heater end, the inner tube bundle is exposed.
This is the heater bundle without its shell.
The excavator maneuvers the bundle for additional cutting.
A welder is cutting the front shell to free it from the tube bundle. The tube bundle will be shipped to the recycling facility.

Lastly, more images can be found in our image gallery. Click Here.
The TRC team and Austin Energy has completed the first phase of the project. While the haul road and parking lot are not quite complete, the team has started on the next phase of the project which is Abatement and Decontamination. This phase will last nearly 5 months and expect this phase to last from the end of January to the beginning of July.
Approximately the next 5 months will be dedicated to asbestos removal and the removal began in January and will last until July of 2012. The highly trained team has started the work and are using the following yellow steel containers to contain the asbestos while awaiting transport.
These containers hold all of the asbestos removed and will not be opened until they arrive at the certified landfills.

Frequently Asked Questions:
1. When will the project start?
2. When will the project end?
Anticipated date is in Q4 2013
3. What is the project timeline?
The removal of the power plant will be completed in 2013 and additional site decontamination and removal of underground utilities will continue for about another year before the area surrounding the Austin Energy transmission facilities is transferred to the City of Austin Parks Department.
4. What percentage or what time frame will be dedicated to the “asbestos removal” portion of the plan? Is it during the entire 18 months or only during a certain phase of the project?
Asbestos removal will be conducted as needed throughout the entire project implementing asbestos containment and removal procedures whenever asbestos is encountered.
5. Are there any plans by the company who has the contract for Holly Street to sell any of the equipment inside the plant before it is demolished, such as the smaller items like lighting fixtures, work benches, storage cabinets, factory carts and things of that nature?
Under the contract terms that Austin Energy signed with TRC (the City of Austin awarded demolition contractor), TRC owns all of the equipment and materials and nothing will be left in Austin Energy’s possession for disposal. In the event TRC decides to sell some of the smaller items in the Austin area, we will notify the public.
6. Once demolition begins, will the hike and bike trail be rerouted?
The trail will remain in place as is until demolition is completed, then a newly added trail along the plant’s shoreline will reconnect with the existing shoreline trail.
7. What is the plan for the land that the power plant occupies? Park? Housing?
The land that will be left after the four power plant units are removed will remain as Austin Energy property. A fence surrounding this area as well as the switchyard to the North, the substation on the west, and the adjacent statcom facilities will be constructed after the demolition and all remediation activities have been completed. This area is required by Austin Energy to maintain the energized electrical facilities and infrastructure that will continue to supply power to the downtown area and other parts of the city.

Yes it will be kept open during the entire time the plant is being demolished. At no time will the trail be closed. During working hours there will be flaggers that will momentarily stop any joggers or bicyclists where the trail crosses the haul road going into the plant if a truck is approaching the trail crossing.
9. Why are there trucks going up Mildred instead of Pedernales like was stated before?
The trucks going up Mildred are removing material from the Canterbury lift station, a water and waste water project. Truck traffic associated with the Holly Plant removal will only travel on Perdenales and Cesar Chavez streets.
10. Can I park my car on Pedernales street between Canterbury and the Holly power plant?
No. Barricades have been installed on both sides of the road from Canterbury towards the power plant designating the road strictly for construction vehicles only. Any vehicle left in that area will be towed at the owner’s expense.
11. What is the plan for the remaining land that will not be retained by Austin Energy?
Current plans call for approximately 9.3 acres of land surrounding, Austin Energy property that will be kept to service the remaining electrical infrastructure, to be turned over to the City’s Parks and Recreation Department (PARD) for development into a park. PARD has engaged the services of a master planner that will help them develop a plan for park improvements over an area from IH-35 along Lady Bird Lake all the way to Pleasant Valley road on the east. PARD and the master planner will be soliciting public input from neighborhood residents living adjacent to that area sometime this year. Please call PARD for additional information.
12. Is there an emergency plan in place developed by the contractor and Austin Energy during the entire time of the demolition work?
Yes. An emergency plan that responds to any type of abnormal incident like a fire, truck derailment, or personnel injuries has been developed in conjunction with the City’s Fire Department. The Fire Department will be the first responders for any type of emergency that may occur and their fire trucks will use the Pedernales construction route into the plant. The Fire Department has stated that based on their evaluation of the current site and the work being performed, there is nothing unusual that can occur that they cannot respond to and alleviate.
