The taxpayer-funded Grand Parkway (State Highway 99) extension will make many people happy. Proximity to transportation drives home-buying decisions. People eager to “get away from it all” will find the lure of saving 10 minutes on a longer commute irresistible. They will marvel at all the trees around them and speak with pride about their growing community in the forest.

And the flooding, caused by all the environmental destruction, means that downstream residents get to remodel their homes. Or move farther out to avoid future flooding. At which point the cycle will repeat itself in a few years.

Mining sand near pipelines can expose the public to danger through erosion. We’ve seen this at the Triple PG sand mine in Porter where a potentially lethal combination of circumstances came together. 1) MINING 2) in a FLOODWAY 3) too close to PIPELINES 4) created EROSION 5) that undermined and EXPOSED the pipeline 6) to FLOATING DEBRIS and 7) the FORCE of floodwater.
Excavating pits in floodways causes erosion to move upstream and downstream during floods. When the pit is too close to infrastructure, such as bridges (or pipelines), erosion can then threaten their foundations.
Predictable Phenomenon
Headward erosion is a PREDICTABLE phenomenon. It’s as certain as gravity causing dirt to fall into a hole. Except in the case of the Triple PG sand mine, floodwater gave gravity an assist. It pushed the dirt into the hole. The hole, in this case, is the sand pit on the left below. The floodwater came from the top of the frame.
Headward erosion cut right through the pipeline crossing that paralleled what used to be a roadaround the mine.
This doesn’t happen every day. It’s sporadic. It happens during floods. But that makes it no less predictable.
How Triple PG Grew Toward, Between and Past Pipelines
The images below show the growth of the Triple PG Sand Mine northward into Montgomery County. In 1995, the mine was 2,000 to 3,000 feet away from the pipelines.
1995
2017 Pre-Harvey
The mine kept expanding to the west and north. Just before Harvey, notice how Triple PG had mined right up the pipeline and beyond it, into the danger zone between the pipeline corridors.
Then came Harvey.
2017 Post-Harvey
During Harvey, headward erosion took out about a 200-foot wide section of earth supporting the natural gas pipeline (also seen in the helicopter photo above). Harvey also elongated the lake in the middle of the pipeline corridors.
Then in 2019, this area had a major flood in May and Tropical Storm Imelda in September. The major breach widened and the lake elongated even more.
2019 Post-Imelda
Imelda widened the Harvey breach so wide and deep that it exposed more pipeline. (See photo below).
Exposed pipeline has no protection from floodwaters carrying trees, cars, houses or other debris downstream. A major collision could cause an explosion. But that’s not even the biggest potential catastrophe at the Triple PG mine.
Now … For the Real Disaster Scenario
Looking at a wider satellite image (below), we can see that the mine is now closing in on the HVL pipelines from the south AND the north. It brackets them.
Water flows from top to bottom in the image above. Note how Caney Creek bends near the white line above. During Imelda, floodwater cut through that area into the big northern pond at this bend instead of following the natural stream bed. See below.
Without constant repairs like you see above, Caney Creek could soon reroute itself through the big pit on the left below. Erosion on both sides of the utility corridor could expose the HVL pipelines – just as it did the natural gas pipelines. Not likely, you say?
A breach on the left would reroute Caney Creek right across the pipelines buried in the utility corridor on the right.
In the last three years, the two ponds along this line have grown closer together by more than 1000 feet. The ponds now are within a few feet of actually touching the pipeline corridor on both sides. Continued erosion could soon threaten the HVL pipelines in the middle if nothing is done to stop it.
Why is This Potentially MORE Dangerous?
Compared to exposing a natural gas pipeline, exposing liquid pipelines is far more dangerous.
When a natural gas pipeline explodes it creates a fireball that could kill anyone near it.
But when HVL pipelines rupture, they spew poisonous liquids. And if those pipelines rupture during a flood, those poisonous liquids will flow right into the source of drinking water for two million people – Lake Houston. This is why sand mining in floodways near pipelines is a bad idea.

https://i0.wp.com/reduceflooding.com/wp-content/uploads/2019/12/Pit-Capture-North-Big-Pond.jpg?fit=1200%2C800&ssl=18001200adminadmin2019-12-07 18:37:282019-12-07 21:25:23From Erosion to Explosion: Why It’s Dangerous to Mine Sand Near Streams and Pipelines
Note: This post has been updated at 3:30 a.m. with information from Kinder Morgan.
The Texas Attorney General is suing the Triple PG Mine for dike breaches that allegedly discharged process wastewater into the drinking water supply of 2 million Houstonians. I photographed multiple dike breaches there in May, September, October and November. On Tuesday this week, I flew over the mine again and noticed something in one of the unfilled breaches: an exposed natural gas pipeline. Kinder Morgan, the line’s owner has had three washouts around this line in two years, according to a spokesman. Currently the line is filled with inert gas until it can be repaired, so there is no immediate danger. However, the repeated washouts raise questions about the safety of mining sand around pipelines.
Exposed Pipeline in Danger Zone
These pictures tell the story.
Flying up Caney Creek on 12/3/2019, I took this photograph looking toward the mine (west) in the background. Note the exposed pipeline.
When I got home, I enlarged that sign in the foreground to see what it said.
Flying over the trees, here’s what you see looking northwest. Notice the exposed pipeline in the bottom right of the photo. It aims toward a massive 183-foot breach in the mine’s northern dike created by Hurricane Harvey. Obviously, moving water exerts tremendous force in this area. See below.
The most recent erosion exposing the pipeline happened during Imelda on September 19th, according to Kinder Morgan.
Here’s what a close up of the pipeline looks like.
Close up shows downed trees all around the pipeline from the Imelda flood.
One tree has fallen on the pipeline like a guillotine.
A second Kinder Morgan spokesperson characterized this as a MAJOR natural gas pipeline.
He said the first two washouts happened during Harvey in the major and minor breaches shown in the photos above. After Harvey, they buried the pipeline under the major breach and filled in the smaller breach.
Then came Imelda. The smaller breach washed out again, creating the third exposure.
Kinder Morgan has not repaired the small breach this time because they can’t get to it. It has been 78 days since Imelda and the mine has yet to repair the road leading to the exposed pipeline.
Previous photographic analysis suggested that during Tropical Storm Imelda, 42,000 cubic feet per second coming from Peach and Caney Creeks (out of frame in the upper right of the photograph above) captured this mine’s pit. That means, the creeks likely rerouted themselves through the mine during the flood.
Here’s another view from a slightly different angle.
Another angle shows more of the exposed pipeline and the erosion around it.
I feel only a little bit safer knowing that the mine’s owners have agreed to stop dredging until the AG’s lawsuit goes to trial next year.
Another Port Neches in Porter?
According to Josh Alberson, a number of major pipelines run through this area. The Texas Railroad Commission’s GIS viewer shows the Kinder Morgan natural gas line crossing the property plus the following:
Plains Pipeline – Red Oak Pipeline (20”) moving crude
The more I look at this mine, the more surprised I am that people have not gotten killed here. It reeks of danger.
These repeated breaches and the exposed pipelines remind me of pipeline incidents farther down the river. They destroyed lives and properties in previous floods when lines ruptured from collisions with floating debris. We’re just been lucky so far.
Hollywood Blockbuster in the Making
I’ve nicknamed this mine “Death Wish VII” after one of my favorite movie series. I can’t wait until the next sequel comes out. Some friends in Hollywood are working on a treatment already. “Cardiologist turned sand miner pollutes drinking water of 2 million people, burns down East Texas, and is named Citizen of the Year by TACA.” It has all the earmarks of a Hollywood blockbuster. But seriously, I think TACA has more class than that. They would probably name him Citizen of the Decade.
Now, back to our regularly scheduled blogging. So much for satire.
Pipeline Incidents Cost 3X More Public Lives than Industry Lives
I’m dead serious now. Thank God that there’s inert gas in this pipeline for now. But what happens in the next flood when it’s flammable gas. What if its exposed for a fourth time and more trees start slamming into it.
Two things jump out at me: the public sustains roughly three times more injuries and fatalities than industry, and the costs are staggering – in the billions.
I have already notified the TCEQ and MSHA. My feeling? We shouldn’t be mining sand in floodways. And we especially shouldn’t be mining sand in floodways criss-crossed with pipelines. The mines accelerate the potential for washouts. And that exposes everyone to more danger.

The Liberty Materials Mine in Conroe on the West Fork of the San Jacinto was cited last month for allegedly discharging 56 million gallons of wastewater loaded with up to 25 times the normal amount of sediment. When we look at the issue of sediment in the river and how it affects flooding, such breaches contribute to the problem. But it’s not just what such sand mines discharge. It’s also about what the wetlands they were carved from don’t hold back any more.
Before there was a Liberty Materials in Conroe, the area they now occupy contained many densely forested wetlands. Now there is nothing to slow down the water during heavy rains. Much more sand and sediment are exposed. And the wetlands are no longer there to filter it. It’s a double whammy. We get it coming and going.
Visually, it appears that wetlands once covered roughly half the area of this mine. But what was actually there?
US Geological Survey (USGS) and US Fish and Wildlife Service (USFWS) use a five character alpha-numeric code to classify wetlands. Liberty Materials operates in areas that were classified as PFO1A and PEM1A.
P stands for the class: Palustrine. Palustrine wetlands include any inland wetland that lacks flowing water. The word palustrine comes from the Latin word palus or marsh. Wetlands within this category include inland marshes, swamps and floodplains covered by vegetation.
The second two letters in each case stand for the subclass: FOrested or EMergent. Forested means it had broad-leaved, deciduous trees or shrubs taller than 6 meters. Emergent means it had aquatic plants.
These were areas that could store large volumes of water during floods. Plus, they had vegetation that could suck it up.
Trees Soak Up Water, Too
Trees can soak up 50 to 300 gallons of water in a day depending on their size, age and type. They send it back into the atmosphere; let’s use 100 gallons as a conservative average and do some simple math to calculate their contribution to flood reduction.
The Liberty sand mine complex comprises more than a thousand acres. That’s 500,000 trees each soaking up 100 gallons of water per day. Or 50 million gallons of water per day.
That’s about the same amount that the TCEQ estimates the Liberty Mine discharged downstream in one breach.
Personally, I’d rather have the trees and wetlands than white water and a river that’s so silted up it contributes to flooding.
Influence of Wetlands on Flooding
Imagine a sand box that’s 1.5 miles wide and 2.5 miles long. Here’s what it looked like the day after the peak of Hurricane Harvey.
Image from 8/30/2017 of Liberty Mine one day after the peak of Harvey.
And here’s why. Note how closely the extend of flooding matches the extent of the flood plains. Like almost all mines on the West Fork, this one lies substantially within the floodway and floodplain.
Cross-hatched = floodway; aqua = 100 year; tan = 500 year floodplain.
Is Liberty’s Luck Running Low?
If these people had the strongest dikes in the world, maybe you could cut them some slack. But they don’t. They breach repeatedly.
About a month after allegedly discharging 56 million gallons of process wastewater into the West Fork, the only thing holding back another discharge at the Liberty Mine is a couple feet of sand. Photo taken on 12/3/2019.
We need sand, but not at the expense of floods and the environment. Maybe it’s time for TACA to run some of its members out of Texas. That do-good routine they stage in Austin every other year could be in jeopardy with members like Liberty. See below.

Behind-the-scenes work for the next phase of dredging has already started. The City, County and State are working together on a $30 million grant application for submission this month. The legislature earmarked the money for dredging at the confluence of the San Jacinto and Lake Houston. However, the money must go through the Texas Water Development Board (TWDB) to Harris County and then the Harris County Flood Control District.
Circuitous Route for Funding
The supplemental appropriations bill, SB500, that the legislature approved dictates the circuitous route for funding. See the exact text from SB500 below.
“Out of funds appropriated in Subsection (1), $30 million is dedicated to the Texas Water Development Board to provide a grant to Harris County for the purchase and operation of equipment to remove accumulated siltation and sediment deposits located at the confluence of the San Jacinto River and Lake Houston.”
DIY vs. Outsourcing
State Representative Dan Huberty, who authored the SB500 amendment, has worked closely with all parties involved to explore the most cost-effective and timely solutions. For instance, Flood Control explored how much it would cost to hire an outside company for dredging versus buying the equipment and doing it themselves. Said Huberty, “In my discussion with the TWDB last week, they have agreed we can buy equipment if we need to, which is the direction we are pushing for at this time.” However, that option would take longer to implement and the money must be spent within the current bi-annum – by law.
Long Term vs. Immediate Needs
Meanwhile, the East and West Forks of the San Jacinto have urgent, immediate dredging needs, too. So the partners could break the work up and pursue both DIY and outsourcing options.
Said Huberty, “I met with DRC (Disaster Recovery Corporation) a week ago. DRC has an ongoing contract with both the City and County for debris removal from Lake Houston and they are still removing debris from the lake. So they might be an option that would let us deploy faster.”
DRC is the parent company of Callan Marine, a subcontractor during the Army Corps’ Emergency West Fork Dredging project after Hurricane Harvey.
The dredges are gone but the pipe is not. The quarter-mile long sections of pipe used in the initial Emergency West Fork Dredging Project have been broken down into smaller sections for transport, but much of it remains on the West Fork.Photo taken 12/3/2019.
Additional Sources of Funding
Huberty also said that, “In addition to the $30 million, the Houston Mayor Sylvester Turner and Council Member Dave Martin committed last weekend to help us fund this in partnership with Harris County Flood Control.” The City committed approximately $6 million, according to Huberty.

The project costs $351 million and will provide water to the Northeast Purification Plant. Photo taken 12/3/2019.
“In addition,” says Huberty, “I spoke to the Governor’s staff this weekend. We still have money left over from Harvey debris removal. That’s approximately another $16 million. They told us we can spend the money on the river and lake, but not for other purposes. This will let us complete the mouth bar dredging and get mechanical dredging done in areas like Huffman and Atascocita. The scope of the project is expanding, which is very good news. We’ll be able to help more people.”
Smaller mouth bars have set up around the lake at the entrance to drainage ditches, like this one in Atascocita near Walden. Photo taken on 10/4/2019. Such blockages can force water up, out and over the banks into neighborhoods during large rains.
Next Step: Commissioners’ Court Needs to Approve Grant Request
The ball, at this moment, is in Flood Control’s court. Commissioners’ Court must approve all grant requests made by any part of the County. Says Huberty, “There will be an item on the December 17th Commissioners Court agenda requesting permission from the Court to submit the grant application to TWDB. All parties involved have already had discussions with the TWDB staff and are working on the grant application paperwork.”
Early next week Huberty plans to meet with John Blount, the Harris County Engineer; Stephen Costello, the Mayor’s Flood Czar; and John Sullivan, President of DRC.
Constant Dredging for Foreseeable Future
“In my discussions with all interested parties,” said Huberty, “we should have the application submitted by year end. We have been pushing to get it awarded quickly. It is a formality. We need to spend this money quickly which works to our advantage. We can always go back to the legislature for more after that.”
“All of these initiatives will ensure we can have constant, permanent dredging on the Lake for the foreseeable future,” said Huberty. “I am very pleased with the result and look forward to getting this project started.”

At the Kingwood Town Hall meeting on October 17th, 2019, Mayor Sylvester Turner read a letter from lawyer J. Carey Gray who represents Perry Homes and its subsidiaries against hundreds of flooded Elm Grove homeowners. The letter laid out a timetable – extending more than 2 years into the future – for completion of the detention ponds on the troubled Woodridge Village subdivision. The first step: finish the S2 pond, which was already substantially complete. Perry Homes gave itself 30-45 days for that task. As nonsensical as that sounded on October 17, they managed to miss the deadline … by not showing up … until after the deadline.
Deadline Expired Yesterday With No Improvements to Pond
Yesterday marked 45 days since Lawyer Gray delivered his letter to the Houston City Attorney. Since then crews have worked several days on adding a concrete lining to a small portion of Taylor Gully. They also replaced some eroded dirt along the northern edge of S2. Still incomplete, however are:
Excavation of the remaining dirt
Grass to stabilize the soil on the banks
A perimeter road required by the Montgomery County Drainage Criteria Manual
Lining for a severely eroded spillway between Taylor Gully and S2
Drainage of the detention pond
Backslope interceptor swales
Photos Demonstrate Lack of Progress
Here’s how the pond looked in September, two days after Imelda.
Status of S2 Pond on September 21, 2019, two days after ImeldaStatus of S2 Pond on November 4, 2019, two and a half weeks after J. Carey Gray’s letter to City Attorney.
Here’s what it looks like today, 46 days after J. Carey Gray’s letter to the City Attorney. They had made some progress on lining the Taylor Gully channel behind the pond. But as far as the pond itself went, there was a lone excavator moving dirt that had eroded into the pond back up on the banks. That’s because they failed to establish grass there.
One day after the deadline for completing the S2 detention pond, Perry Homes had a lone excavator pushing eroded dirt back up onto the banks. Photo taken 12/3/2019.Photo taken 12/3/2019. Hardly a bustling construction site with contractors racing to meet deadlines.
Only 735 more days before all the detention ponds are complete … assuming they can meet any of their own deadlines.
Questions Raised by Lack of Performance
The failure to meet this first deadline raises questions:
Is Perry Homes sincere? Can they ever be trusted for anything ever again?
Has Perry Homes lost its ability to deliver? Is the company financially crippled beyond repair?
Did Sylvester Turner extract terms from Perry Homes designed to get him through the general election?
Or did Perry Homes play Sylvester Turner to torpedo his chances in a runoff election?
Did Kathy Perry Britton, CEO of Perry Homes, think no one would remember?
Is Perry Homes holding the threat of future flooding over Elm Grove residents to force a settlement of their lawsuits?
If it’s the latter and there’s another flood – with this record of foot dragging – they’ve nuked themselves. It’s a Harvard Business School and Harvard Law School case study that will go down in the Annals of Corporate Stupidity.
What can explain this level of ineptitude?
This has to be a huge embarrassment for the City of Houston and Montgomery County. It’s also a PR debacle for Sylvester Turner … in the middle of a hotly contested runoff election. Turner can’t do anything about that now except to tell the City Attorney to sharpen his spurs.
But if I were MoCo, I would claim Perry Homes’ performance bond and finish the work myself.

A Texas Commission on Environmental Quality (TCEQ) investigation into the mysterious white water on the West Fork, focused on sand mining upstream. TCEQ cited Liberty Materials for allegedly discharging 56 million gallons of milky-white water into the West Fork.
The mine’s manager said he “didn’t have a clue” about when, why, or how one of the mine’s pits lost 4 feet of water. A water sample showed nearly 25 times the normal amount of dissolved solids.

The Liberty Materials mine, like virtually all of the mines on the West Fork, sits in the floodway and floodplain. It’s a mile and a half wide and almost three miles long. About a 1000 acres altogether.

That’s a lot of sand and sediment exposed to the ravages of floodwater.
But the irony in this case is that there was no flood immediately before the breaches.
The gage at State Highway 242 near the Liberty mine shows 2.4 inches of rain during a 3 day period starting six days before the white-water incident.
Rainfall at SH242 and San Jacinto West Form from October 27 through November 3, 2019. Source: HarrisCountyFWS.org.
Late October rainfall caused the West Fork to rise about 3 feet, but the river had another 18 feet to rise before flooding.
That amount of rainfall caused the river to rise about 3 feet. But it was still 18 feet away from flooding!
Alternative Breach Scenarios
So if flooding didn’t do it, how did the water get out of the mine? One possibility is that the terrain funneled rainwater into the pond and caused it to overflow. The overflow then started a fissure which widened into the Grand Canyon of the West Fork.
Several mining engineers suggested other alternative scenarios:
Industrial sabotage by a disgruntled employee
Liquefaction of the sand around the perimeter of pits as they filled with rainwater
A heavy truck driving over sand about to liquify
They needed to clean out the pond and intentionally lowered the level
Needed purer water to create acceptable frack sand
“The Boss Made Me Do It”, possibly related to one of the two points above
The mine manager interviewed by the TCEQ claims he doesn’t know when, why, or how the breach happened. Yet it caused a four-foot drop in the level of a major pond for more than a week.
To paraphrase the famous quote from Hamlet, “Methinks, the man professes ignorance too much.” By that I mean, the denials cause him to lose credibility. If your swimming pool suddenly dropped four feet, wouldn’t you want to know the cause?
His responses hint that something else is going on here. We may never know what. Despite tens of millions of gallons of pollution being poured into the West Fork, these cases rarely go to trial.
All the more reason to establish greater setbacks from rivers for sand mines.
The state legislature needs to make it more difficult for “accidents” like these to happen.

Yesterday, I posted the results of a TCEQ investigation into the Liberty Materials sand mine in Conroe. TCEQ alleged that the mine discharged 56 million gallons of white milky pollution into the West Fork of the San Jacinto. They also found that a water sample taken at the mine contained almost 25X the normal level of dissolved solids. The report mentions four other recent investigations that resulted in citations for unauthorized discharges.
October Flyover Shows Other Discharges At Same Mine
Today, I reviewed aerial photos of the mine that I took on a flyover in October, before the alleged unauthorized discharge.
Note the color of water in two ponds at the Liberty site. All photos taken on 10/2/2019.Mine in background and West Fork in foreground. Notice discharge despite attempt to plug leak.Same breach from opposite angleAnother breach almost looks like it was designed to funnel water into the river.In addition to the major breaches above, note a smaller breach here...…and the water escaping from the pond alongside the road. Those pipes running along the river sure do make it hard for canoeists and kayakers to get downstream.
More Than a Dozen Discharges Seen on One Day
The TCEQ cited Liberty for 4 previous unauthorized discharges in the last 2.5 years. Had they visited the mine on October 2nd, they might have found that many violations in one day.
And these weren’t the only breaches I found that day. Counting those at other mines on the East and West Forks, TCEQ could have easily tallied another dozen violations on this one day.
Sad to say, this industry has an abysmal health and safety record.

Tree Lane Bridge over Ben’s Branch
Bear Branch Elementary and Child Time on Tree Lane in Kingwood sit right next to a bridge over Ben’s Branch. Most people in Kingwood don’t need a reminder of the power of moving water. But for those with short memories this is it. A floodway and floodplain more than 250 feet wide narrows down to 80 feet at the bridge.
Lap-Band Surgery for the Creek
It’s like the creek had lap-band surgery.
The predictable result: water backs up behind the bridge and then jets through the opening. The water has literally torn the concrete lining designed to prevent erosion into confetti. Note how the erosion has also exposed a pipeline.
Note the erosion immediately downstream from the bridge.
Erosion immediately downstream from the Tree Lane Bridge above. Wood chips are from HCFCD crews de-snagging the banks of the creek. Photo taken 11/30/2019.
Powerful lessons for anyone who thinks he or she can outsmart Mother Nature for long.
One More Thing to Consider in Kingwood Area Drainage Analysis
Harris County Flood Control is in the middle of its Kingwood Area Drainage Analysis right now. I hope they take a close look at this. While the bridge itself seems stable at this point, if this erosion continues unabated, that could easily change.
