Workers at the Pantex High Explosives Pressing Facility this month passed the 85% construction completion mark on construction of the 45,000 square-foot facility, which will combine High Explosives (HE) operations from numerous outdated buildings into one state-of-the-art facility. Completion of the project will help to bolster Pantex’s status as the Department of Energy’s High Explosives Center of Excellence for HE manufacturing.
The roof has been completed, officially enclosing the exterior of the facility, which allows the contractor to continue work inside during inclement weather. The roadway paving around the facility has started, which will allow for all-weather access.
The new state-of-the-art HE presses, which take advantage of advanced isostatic pressing techniques, have been installed. The process equipment has arrived and is being installed. All Blast-Resistant Doors have been installed. Offices have been built and are being painted.
The major remaining work activities include installation of overhead cranes, flooring and mechanical/electrical systems.
Acting NNSA Administrator Bruce Held and NPO Manager Steve Erhart toured the HEPF on November 7th.
Construction of the $65 million facility began in late 2011 and is expected to be complete in May, 2014. B&W Pantex has begun pre start up activities to meet the CD-4 (approval to start operations) date of September 2016.
The construction effort is being managed by the U.S Army Corps of Engineers and the design effort/plant support is being led by B&W Pantex with a design subcontract to CH2M Hill.

We take them for granted. Bugs, insects, arachnids, mollusks, crustaceans, invertebrates – the little guys.
Me personally – I can walk right up to a hidden rattlesnake that I am radio-tracking and record its location with a GPS Unit. I can let a bobcat out of a trap after we have poked and prodded him.
However, that spider that I am trying to remove from the wall in the kitchen – well, let’s just say that a sudden move by the spider is likely to cause a similar reaction in me.
Macroinvertebrates are the tiniest of the noticeable Pantexans, but they are very important. Some we need because they control each other (spiders, some wasps, and others), some contribute by scavenging or recycling, while most form the foundation of the animal kingdom’s food chain.
Within my role at Pantex, it is just as important to characterize what we have in the way of macroinvertebrates as it is the larger animals. In what was the first of eleven wildlife research projects initiated over the last fourteen years at Pantex, during 2000 – 2001 we contracted with Dr. David Sissom of West Texas A&M University to survey macroinvertebrate diversity among different habitat types at Pantex. These types included shortgrass prairie, shortgrass prairie with prescribed wildlife habitat management, restored prairie, cropland, playa edge, and disturbed/impacted habitat. Some wetland invertebrate work had been performed at Pantex in the past, as had some collections of terrestrial species. However, previous work was limited to few collection techniques and habitats.
The survey documented nearly 900 species of macroinvertebrates, including two state records and a species that has only been recorded one other time in Texas. Shortgrass prairie (both types sampled) and playa edge sites, which were also within shortgrass prairie, were consistently superior in species richness than the other habitat types. The lowest species richness was found in areas kept mowed short, restored prairie sites, and grain sorghum fields, respectively. Restored prairie takes a while to develop plant diversity, and thus to begin to function as prairie habitat.
Species diversity and abundance is a pretty good indication of habitat quality. And some species like songbirds and gamebirds require macroinvertebrates in their diets, particularly their growing offspring. These same birds need the grassland habitat for nesting cover.
In closing, not only did this project produce data for Pantex, it also gave students experience with working in the field, and produced data that has been shared with the scientific community. To date, one technical note and one book has been published from this work. It has also been included in presentations at meetings that summarize Pantex research.

Officers run more than 50 miles to raise awareness
For the third year in a row, Pantex Security Police Officers Byron Logan and Randy Stokes took to the area's roads and highways to raise awareness of the hungry in the Texas Panhandle. Logan and Stokes biked and ran and biked more than 50 miles Friday during the annual Run Against Hunger, gathering food and donations for the High Plains Food Bank.

Who doesn’t love bald eagles? My first exposures to them were the several that spent the winters at Lake Rita Blanca near my hometown of Dalhart, TX, when I was growing up. During those months each year of my childhood, it was a big deal to see this majestic bird. They’d be perched in a tree, sitting on the ice, or soaring above the lake. If the latter, the thousands of Rita Blanca’s ducks and geese would whirl around in the sky above the lake with nervousness.
Later, it was my job with the Texas Parks and Wildlife Department to count them each winter as part of my duties as the Migratory Birds and Wetlands Biologist for this region. During ground and aerial surveys, I’d find them often in association with concentrations of waterfowl. The most I ever saw in a small area was ~40 that were congregated near a large waterfowl (ducks and geese) roost numbering near 180,000 birds. There, they were feeding on sick and dead ducks and geese that were victims of the waterfowl disease, avian cholera.
At Pantex, the bald eagle can be readily seen around our playa lakes and our prairie dog colonies during the winter months. Similar to playa lakes providing concentrated sources of waterfowl for them, prairie dog colonies provide prey in the form of prairie dogs, rabbits, and mice and rats; many of which are snatched from smaller, faster birds of prey. In the fall and spring, snakes likely contribute to their diet. You may spy a bald eagle flying overhead, practically anywhere.
Bald eagles nest throughout much of the U.S., but particularly in the north and in the Gulf Coast States. Until recently, the last known nest in the Panhandle was more than 50 years ago. However, a pair has nested in the Dalhart area, annually, over the last several years. Most nests are near water, where the young are fed heavily on fish. However, the Dalhart nest is not associated with water and the U.S.G.S. Cooperative Fish and Wildlife Research Unit at Texas Tech has found that the young are fed primarily on prairie dogs, cottontails, and black-tailed jackrabbits.
Bald eagles get their white head and tail when they are five years old. These contrast greatly with their very dark body plumage. Juveniles are also darker then the golden eagles they may resemble. Keep your eyes peeled – chances are that during the winter months you will have an opportunity to see a bald eagle. I have even seen them flying right over town. Our nation’s symbol is fairly common here; in fact, it is one of the Texas Panhandle’s best kept wildlife secrets.

I grabbed a cup of coffee, hopped into my pickup, and headed out towards what we refer to as the Playa 1 Playa Management Unit. It’s just a quarter of a mile or so up the road from my building. I pull over to the shoulder and watch as several pheasants flush from the sorghum stalks to my right into the grassland cover situated across the road and to the left. It is there that I notice a nice mule deer buck that is working his way downslope towards the heavier cover of Playa 1. He’s alone this time, but usually associated with a handful of mule deer that can be seen pretty regularly in this vicinity. Across our 18,000 acres there are a few other places that mule deer associate with, and like elsewhere in the region this time of year, fields of winter wheat can concentrate them.
And then there are the white-tailed deer. This is where I am intrigued.
Growing up, there were very few white-tailed deer in this plains country. In fact, my mention of them being present in the western Canadian River drainage sparked interest from one of my Texas Tech professors and this led to an aerial survey, my first magazine publication (co-authored with the professor), and talk of a M.S./Ph.D. project that would include the professor’s former mule deer-only study sites.
All of this really hit home to me about a decade later when I was running a roadside pheasant survey in the Pantex-like wheat-sorghum-corn-playa country up near Etter in Moore County. That morning I counted more white-tailed deer than I did pheasants. On and around Pantex, mule deer numbers exceed those of white-tailed deer, but still white-tails are a regular inhabitant of the facility.
Although documented in the past, deer observations became commonplace on Pantex beginning in 2003. Enough vehicle-deer collisions have occurred that we now have “watch for wildlife” signs at each entrance and deer crossing signs at other key locations. This fall, conversations indicate a general belief that our deer numbers are way up this year. Our observations don’t support that. We can still go out to certain places and see small groups of deer; certainly not everywhere, or in unprecedented numbers.
A lot of the recent observations are likely more due to where some of the deer are operating and that we have entered a period when deer activity typically increases. Crop harvests have affected available food and cover, as may the first killing frosts, causing deer to move into new areas or make longer trips to food sources. In addition, the advancing breeding season also has a big effect on deer activity.
My friend Calvin Richardson of the Texas Parks and Wildlife Department (TPWD) tells me that their surveys to the north of the Plant in the Canadian River breaks and basin reveal about a 125-175 acres/deer. For comparison, high deer densities in Central Texas can exceed 5 acres/deer. As expected, as you come up out of the Canadian River basin into the flat cultivated country the numbers drop way off.
Here at Pantex, we have run a set of three 24-mile spotlight surveys each fall since I arrived in 1999 and our terrain is wide open, with high visibility. Our first recording of a deer on this survey was in 2004, and the highest number that we have observed since that time is 20. I fully understand that deer come and go, and thus numbers fluctuate, but the highest deer density estimate that I can come up with is 900 acres/deer. Regardless whether that is a high or a norm, this is very believable considering our habitat, Mr. Richardson’s remarks, and where and how many deer we see during our travels.
The fact is the High Plains of the Texas Panhandle have become deer country, and what a beautiful sight they make in our wide-open, flat terrain. However, wherever you may have to drive, be observant for deer and drive safely.
