1/16/2025 – Harris County Precinct 3 Commissioner Tom Ramsey, PE, and Distict E Houston City Council Member Fred Flickinger discussed the status of numerous flood projects at a meeting of the Kingwood Area Republican Women today at the Oakhurst Golf Club.
Ramsey addressing Kingwood Area Republican Women’s Club today.
Among the projects they covered were:
Taylor Gully Improvements/Woodridge Village Detention
Legal Changes Governing Pre-Release of Water from Lakes
Edgewater Park
Dredging
Medians
Flood Tunnels
Subsidence
Below are the highlights. They also discussed other issues such as median maintenance, vine control, crime, taxes, government waste, elections and more. But I will focus primarily on infrastructure issues related to flooding – especially Taylor Gully and Woodridge Village, because of pending approvals this month.
Taylor Gully/Woodridge Village
After Perry Homes clearcut approximately 270 acres in Montgomery County, hundreds of Kingwood homes flooded twice in 2019 along Taylor Gully. Taylor Gully runs through the northern part of Kingwood from Kingwood Park High School to White Oak Creek.
Harris County Flood Control District (HCDFC) began working on mitigation plans in 2021 and presented preliminary recommendations to the community in December, 2022.
The county had high hopes for funding from the Texas General Land Office (GLO) and U.S. Department of Housing and Urban Development (HUD), but those ran into a potential snag. Taylor Gully improvements fit within available HUD funding, but Woodridge Village (the former Perry Homes Property) did not. HCFCD hoped to build more stormwater detention basin capacity on Woodridge to help control Taylor Gully expenses downstream.
Regardless HCFCD pressed forward. They combined the two projects. And according to HCFCD, both now fit with available funding capacity (see “above the line” list on page 2) of the list being presented to Commissioners Court next week on 1/23/25.
The county purchased Woodridge Village in February 2021. Shortly thereafter, HCFCD began an excavation and removal (E&R) contract to get a “head start” on the basins. Indeed, the head start brought the total stormwater detention on the site almost to Atlas-14 standards.
However, HCFCD was forced to terminate the E&R contract before the basins could be completed. That was to comply with HUD requirements while HUD considered the grant application.
This is potentially great news for the people who live in Sherwood Trails, Elm Grove, Mills Branch and Woodstream.
Watch commissioner’s court closely next Thursday. The Kingwood area drainage study named this project as one of the two most important in Kingwood.
Kingwood Diversion Ditch and Upstream Detention
The Kingwood Diversion Ditch was the other of the two most important projects. The Diversion Ditch takes floodwaters out of Bens Branch, which runs diagonally through the center of Kingwood from St. Martha Catholic Church to River Grove Park.
Improving the Diversion Ditch would reduce flood risk for hundreds of homes and apartments, Kingwood High School, Town Center, and Kings Harbor. Both Bens Branch and the Diversion Ditch currently have a two-year level of service. That means they have a 50% chance of coming out of their banks in any given year.
Ramsey estimated today that the project could cost $60 million. However, he also indicated that U.S. Congressman Dan Crenshaw “got us enough money so we can do the final engineering.”
Eric Heppen, Precinct 3 engineer, later stated that once Commissioners Court approves the preliminary report, it will be made public.
Flickinger emphasized that he is talking with Montgomery County, trying to get them to retain more of their floodwaters. He raised concerns about a new 200,000 sq. ft. convention center planned for US59 at Valley Ranch. “That will generate a lot of runoff that could come down to us, unless we work together to find a way to hold that water up there.”

Additional Floodgates for Lake Houston
Shortly after Harvey, many people pinned their flood-mitigation hopes on additional floodgates for the Lake Houston dam. The idea: to lower the lake faster when it becomes certain that a storm will flood the area. The existing gates have 1/15th the capacity of Lake Conroe’s. So Lake Houston must start releasing far earlier in advance of storms than Lake Conroe. And by the time Lake Houston is lowered, storms can veer away, wasting valuable water.
So Conroe tends to hold its water back until it is absolutely certain. At that point, it has no other choice than to release water at high rates that flood people downstream.
Being able to lower Lake Houston faster would let Lake Conroe release earlier and slower, smoothing out flood peaks downstream.
Ramsey estimated the cost of 11 new floodgates that could release 80,000 cubic feet per second at $150 million. He said the final engineering should be completed this year. He also said that bidding and construction could start in 2026.
Legal Changes Governing Pre-Release of Water
Flickinger addressed a related legal issue. State law limits the release of water from lakes; it must be only for defined beneficial uses and flood control is not one of them.
So, Flickinger is working with State Rep. Charles Cunningham to change that and increase the limit. “Bottom line,” he said, “is that we need to release more water sooner rather than holding it back until we’re adding to the crest of the flood.”
Flickinger is also working with the San Jacinto River Authority on these changes.
Edgewater Park
After Harvey, the County acquired land on the northeast corner of the West Fork and US59, which will turn into Edgewater Park. It will also connect the Houston Parks Board’s West Fork Greenway with the Spring Creek Nature Trail. Ramsey said the plans will be made public very soon. After the meeting, Precinct 3 engineer Eric Heppen confirmed the plans were 99% complete.
Ramsey said, “Soon, you’ll be able to go from Kingwood to Tomball and not cross a road.” That should be a tremendous draw for hikers and bikers and the entire area.
Dredging
Flickinger discussed two aspects of dredging not covered in last night’s post. First, he is seeking additional funding to continue the current program while the dredge is on the lake. Second, he feels opportunities exist to increase efficiency.
I asked what he meant by that. FEMA restrictions on the funds currently being used limit the dredging to “pre-Harvey” conditions. That means, Callan Marine, the contractor, must dredge to different depths to match the exact bottom profile that existed before Harvey. And that requires repositioning the dredge more than if you were just dredging to a uniform depth across wide areas.
The search for additional funding has led Flickinger to the City, the Coastal Water Authority (CWA) and former State Representative Dan Huberty. Huberty was appointed to the board of CWA last last year by Houston Mayor John Whitmire.
Medians
Several people from the audience questioned Flickinger about the medians along Kingwood Drive. He touted the success of his first Median Madness event in November 2024 and announced another on February 22, 2025. Mark your calendar now.
More than 50 volunteers participated in the last vine-cutting extravaganza. He hopes for many more volunteers this time.
Flood Tunnels
The county is getting ready to launch the next phase of its flood tunnel study. Ramsey emphasized that there isn’t enough room in Harris County to poke enough holes in the ground to solve all of our flooding problems. He sees tunnels that carry floodwater from strategic locations as essential parts of the solution.
Eric Heppen, Ramsey’s engineer said that by burying the 40 foot tunnels 80 feet underground, you can double the conveyance in some watersheds, sidestep environmental issues, and avoid having to condemn property.
But many issues have yet to be worked out. For instance, will tunnels be constructed to relieve 2-year, 5-year, 10-year, 25-year or 50-year flooding? More to follow when details become available.
Subsidence
Harris County estimates the area east of Lake Houston will grow by 18,000 homes in the next 10 years. But there currently are no plans to provide them with surface water. So, they will pump groundwater. That means subsidence. And subsidence means flooding, according to Ramsey. He pointed to Conroe as an example. The City’s groundwater pumping has caused subsidence as far south as Harris County.

1/15/25 – The City of Houston’s latest West Fork Dredging Program appears to be off to a fast start. Dredging began about a month ago and has already filled up approximately 10 percent of the placement area. The program was originally estimated to last two years.
Shortly after sunrise yesterday, Callan Marine’s General Pershing Dredge lifted its bit out of the water temporarily as the dredge was repositioned. Note the FM1960 bridge downstream in the upper right.
Pictures Taken 1/14/25
Yesterday morning, the Callan dredge was anchored off Atascocita Point. Just three weeks ago, it began across the river in Kingwood. The pictures below tell the story.
Looking N.Atascocita Point on left and Kingwood on far side of river. Can you spot the Kings Point water tower?
Callan will pump slurry to the placement area through that winding 18″ pipe in the photo above. It goes approximately four miles to an area near the Luce Bayou Interbasin Transfer Canal. See pictures below.
The Amazing Maze
There, Callan separates the water from sand and silt with an ingenious maze. The twists and turns in the maze slow the water down, so sediment drops out of suspension.
Water comes in at the upper right and exits near the same point. Note how the sediment is higher on the wall near the entry, then tapers off. To visually estimate percentage of completion, compare levels on both sides of the diagonal berm in right foreground.
The 35-acre pond currently in use is surrounded by berms approximately 6-8 feet tall that contain the slurry. Callan has room at this same site to build another pond of approximately the same size. The two together will total 70 acres.
Cleared but unfinished areain foregroundwill contain a second pond. Luce Interbasin Transfer Canal on right.Notice how bulldozers have built small temporary walls that channel the slurry away from areas where fill has already reached the full height of the berms.When filled, this area will be high and hard enough to build new homes on.
Bulldozers spread the sediment out in layers that allow excess water to drain out or evaporate. One dredging expert told me that when dry, the sediment will be hard enough to support foundations and homes.
Small, low temporary berms within the placement area concentrate the slurry where workers want it to go.
Water that Doesn’t Evaporate Returns to the Lake
The pictures below track the movement of water within the placement area.
Slurry shoots in from the dredge almost 4 miles away.Then bulldozers spread out and compact the dirt.Water that doesn’t evaporate eventually makes its way through the maze back to the two pipes (center at bottom)Boards in front of the exit pipes control the level of water in the pond and the rate of outflow.After dirt is separated from the water, any remaining water that doesn’t evaporate re-enters Lake Houston (upper left).
Comparison with December
To see how much progress Callan has made, compare the pictures above with the one below taken, just three weeks ago.
Progress as of 12/21/24.
Beneficial Use
I wonder if that return channel will become a ready-made detention basin when the landowner develops the site. This is an ingenious example of “beneficial use” – turning a problem into a solution.
Up the Down Escalator
Nevertheless, there is a cost associated with dredging. Funding for the program comes from FEMA via U.S. Congressman Dan Crenshaw. The City will use money left over from previous West Fork Mouth Bar dredging. Crenshaw secured $125 million in federal funding to cover dredging, including phases already completed.
Some of the sediment shown above comes from natural erosion. Some also comes from upstream sand mining.
With 20 square miles of sand mines in a 20-mile reach of the West Fork between I-45 and US59, the average width of exposed sediment during floods is one mile.
Sometimes I compare flooding issues to trying to walk up a down escalator.
In this case, we’ve failed to establish an effective regulatory regime based on a comprehensive set of best management practices for sand mines. And the public is paying the price in terms of increased flood risk and mitigation costs.
If you haven’t already written the TCEQ to register your concerns about their proposed (but inadequate) best management practices for sand mining, please do so. The public comment period ends on January 24. This post contains more about the problems with the TCEQ’s proposed BMPs. Texans for Responsible Aggregate Mining has even bigger concerns which I posted about yesterday.
Please mail your concerns to Jess Robinson, MC 175, Office of Legal Services, Texas Commission on Environmental Quality, P.O. Box 13087, Austin, Texas 78711-3087. Or you may submit them electronically. Comments must be received by 11:59 p.m. on January 24, 2025, and should reference “APO BMP List Proposal.”
So far, only a handful of people have registered public comments. So please help.

1/14/25 – Texans for Responsible Aggregate Mining (TRAM) has issued a position paper that pans a new set of Best Management Practices (BMPs) for mining that the Texas Commission on Environmental Quality (TCEQ) has proposed. TRAM calls TCEQ’s BMPs “sparse,” “vague,” and “self-evident.”
TRAM asks everyone concerned about flooding and other issues related to aggregate mining to write the TCEQ before the close of public comments on the new BMPs. The deadline is January 24, 2025.
TRAM has also proposed a more comprehensive list of alternative BMPs that it believes will be more effective at minimizing disturbances created by mining.
San Jacinto West Fork mine complex inundated by floodwaters illustrates need for better BMPs
TCEQ BMPs Fail to Address Legislature’s Requirements
Senate Bill 1 in the 2021 Legislative Session required TCEQ “to adopt and make accessible on the commission’s internet website best management practices for aggregate production operations regarding nuisance issues relating to dust, noise, and light…” But the BMPs ignore noise and light.
SB 1397 and House Bill (HB) 1505 in the 2023 Legislative Session then required TCEQ to adopt BMPs related to dust, water use, and water storage. But the proposed BMPs ignore water use.
TCEQ also ignored Texans for Responsible Aggregate Mining’s (TRAM’s) technical team of credentialed professionals. TRAM created a vetted list of BMPs and presented it to the TCEQ for consideration. Instead of drawing from that resource…
“TCEQ spent three years (September 2021 to December 2024) to produce BMPs so sparse, vague, and self-evident, as to be completely irrelevant and useless.”
TRAM
Description of TRAM Concerns
According to TRAM, TCEQ’s draft BMPs weaken TCEQ’s effort to protect public health and natural resources by “pretending to establish new guidelines while actually saying nothing. It is a disservice to taxpayers and to the environment.”
Sparse
In regard to sparse, TRAM says, “The proposed BMP list fails to address many of the real issues associated with APOs, including issues they were directly charged with addressing.”
“While they addressed dust and water storage (albeit inadequately) the TCEQ completely overlooked the “water use” portion of their 2023 charge.” And they still haven’t addressed noise and light pollution from 2021.
“TCEQ has simply failed to comply with their mandates,” says TRAM.
Vague
TRAM also feels that the TCEQ recommendations are “too vague to be useful.” For instance, “Ensure vehicles are driven at reasonable speeds to reduce dust disturbance.” TRAM suggests posting speed limits of 10 or 15 mph for unpaved haul roads. The group believes that the value of a BMP list is in detailing what a “reasonable speed” ought to be.
TRAM gave another example of vagueness. TCEQ proposed “Use fuel-efficient and appropriately-sized equipment to reduce emissions, operation time, and the overall amount of dust you produce.” TRAM questioned what “appropriately sized” meant.
“How is anyone to assess when a BMP is being implemented,” TRAM asked, “if they are described in completely subjective terms like ‘reasonable’ and ‘appropriate’?”
Self-Evident
TRAM also cited TCEQ recommendations that were self-evident. For instance, “Be sure your stockpiles are only as high as your permit allows,” or “The further dust-producing operations are from the site boundaries, the less likely they will be to create a nuisance for any neighbors.”
“Who benefits from these self-evident recommendations and simple reminders to follow the permit requirements?” asked TRAM.
“Completely Inadequate”
TRAM summed up its concerns in two words. “This completely inadequate draft BMP list, three years in the making, only weakens TCEQ’s effort to protect public health and natural resources by pretending to establish new guidelines while actually saying nothing. It is a disservice to taxpayers and to the environment.”
Whatever BMPs TCEQ ultimately settles on, they will neither be required nor incentivized. Still, TRAM believes it is paramount that the list be thorough and well vetted. That’s because, “It will serve to educate the public about what quarry operators could be doing to be good neighbors.”
Send Feedback to TCEQ Now
TRAM and its member organizations ask that you submit public comments to TCEQ at the address or website provided below by the January 24th deadline.
Mail comments to Jess Robinson, MC 175, Office of Legal Services, Texas Commission on Environmental Quality, P.O. Box 13087, Austin, Texas 78711-3087. Or you may submit them electronically. Comments must be received by 11:59 p.m. on January 24, 2025, and should reference “APO BMP List Proposal.”
TRAM suggests mentioning the inadequacies above. The group also suggests including BMPs from TRAM’s list that are most important to you. And insisting TCEQ addresses unaddressed issues required by the Texas Legislature: water use, noise, and light pollution.
More Complete List and Thorough Descriptions Needed
Further, they suggest addressing more issues more completely. For instance, some of the many BMPs that should be included are:
Dust Control: Roads and parking areas for vehicles that will leave the site should be paved.
Light Pollution: Direct light properly and use perimeter barriers to eliminate sky glow, light trespass, and glare.
Mine Management and Truck Safety: Clear roads for school buses by not loading trucks for 30 minutes before and after school bells.
Noise: APOs should monitor the noise exposure at their property line, keeping the noise level below 65 dB if within 880 yards of a residential area, school, or house of worship, and 70 dB if not. Set noise criteria using MSHA on-site guidance and limits from nearby municipalities.
Blasting: Blasting should be monitored with seismographs, located on the perimeter (corners) of the APO property (and in some instances, adjacent or near-by properties in multiple directions).
Water quality: Vegetation is an inexpensive and effective way to protect soil from erosion and filter contaminants, protecting water quality in nearby streams and aquifers. It also protects air quality by holding dust down and filtering the air. Vegetative controls should consist of native plants appropriate for the Texas ecoregion where the site is located and must not include any noxious or invasive species.
Water use: Maximize re-use of process wastewater. Manage fine tailings to reduce volume in settling ponds. Use a tailings thickener system and/or flocculant, as many APOs do. These can provide additional recycled water, reduce water loss and also reduce land use.
Riparian health and safety: In riparian areas, reduce the risk of catastrophic “pit capture” (when a river breaks through the riverbank or constructed levy and runs through the mine pit, as has happened countless times in Texas, due to poor mining practices) by:
Maintaining an undisturbed setback of 50-200 feet from the water’s edge. Create a buffer between mining activities and the waterway.
Leaving vegetation in the buffer.
Minimizing use of heavy equipment in buffers to protect vegetation and reduce soil compaction.
ReduceFlooding.Com Suggestion
ReduceFlooding.com agrees with all of TRAM’s recommendations, but given recent erosion, I would suggest that the minimum safe distance from rivers such as the East and West Forks of the San Jacinto, be 200 feet. Fifty feet can be wiped out in one flood.

Ramsey, Flickinger Discuss Status of Flood Projects
1/16/2025 – Harris County Precinct 3 Commissioner Tom Ramsey, PE, and Distict E Houston City Council Member Fred Flickinger discussed the status of numerous flood projects at a meeting of the Kingwood Area Republican Women today at the Oakhurst Golf Club.
Among the projects they covered were:
Below are the highlights. They also discussed other issues such as median maintenance, vine control, crime, taxes, government waste, elections and more. But I will focus primarily on infrastructure issues related to flooding – especially Taylor Gully and Woodridge Village, because of pending approvals this month.
Taylor Gully/Woodridge Village
After Perry Homes clearcut approximately 270 acres in Montgomery County, hundreds of Kingwood homes flooded twice in 2019 along Taylor Gully. Taylor Gully runs through the northern part of Kingwood from Kingwood Park High School to White Oak Creek.
Harris County Flood Control District (HCDFC) began working on mitigation plans in 2021 and presented preliminary recommendations to the community in December, 2022.
The county had high hopes for funding from the Texas General Land Office (GLO) and U.S. Department of Housing and Urban Development (HUD), but those ran into a potential snag. Taylor Gully improvements fit within available HUD funding, but Woodridge Village (the former Perry Homes Property) did not. HCFCD hoped to build more stormwater detention basin capacity on Woodridge to help control Taylor Gully expenses downstream.
Regardless HCFCD pressed forward. They combined the two projects. And according to HCFCD, both now fit with available funding capacity (see “above the line” list on page 2) of the list being presented to Commissioners Court next week on 1/23/25.
The county purchased Woodridge Village in February 2021. Shortly thereafter, HCFCD began an excavation and removal (E&R) contract to get a “head start” on the basins. Indeed, the head start brought the total stormwater detention on the site almost to Atlas-14 standards.
However, HCFCD was forced to terminate the E&R contract before the basins could be completed. That was to comply with HUD requirements while HUD considered the grant application.
This is potentially great news for the people who live in Sherwood Trails, Elm Grove, Mills Branch and Woodstream.
Watch commissioner’s court closely next Thursday. The Kingwood area drainage study named this project as one of the two most important in Kingwood.
Kingwood Diversion Ditch and Upstream Detention
The Kingwood Diversion Ditch was the other of the two most important projects. The Diversion Ditch takes floodwaters out of Bens Branch, which runs diagonally through the center of Kingwood from St. Martha Catholic Church to River Grove Park.
Improving the Diversion Ditch would reduce flood risk for hundreds of homes and apartments, Kingwood High School, Town Center, and Kings Harbor. Both Bens Branch and the Diversion Ditch currently have a two-year level of service. That means they have a 50% chance of coming out of their banks in any given year.
The District started preliminary engineering in mid-2021. HCFCD will finally present that report to Commissioners Court on February 6, 2025.
Ramsey estimated today that the project could cost $60 million. However, he also indicated that U.S. Congressman Dan Crenshaw “got us enough money so we can do the final engineering.”
Eric Heppen, Precinct 3 engineer, later stated that once Commissioners Court approves the preliminary report, it will be made public.
Flickinger emphasized that he is talking with Montgomery County, trying to get them to retain more of their floodwaters.

New West Fork Dredging Program Off to Fast Start
1/15/25 – The City of Houston’s latest West Fork Dredging Program appears to be off to a fast start. Dredging began about a month ago and has already filled up approximately 10 percent of the placement area. The program was originally estimated to last two years.
Before it’s all over, Callan Marine, the contractor, will dredge 876,672 cubic yards of West Fork sediment from 181 acres near the mouth of the West Fork in Lake Houston.
Pictures Taken 1/14/25
Yesterday morning, the Callan dredge was anchored off Atascocita Point. Just three weeks ago, it began across the river in Kingwood. The pictures below tell the story.
Callan will pump slurry to the placement area through that winding 18″ pipe in the photo above. It goes approximately four miles to an area near the Luce Bayou Interbasin Transfer Canal. See pictures below.
The Amazing Maze
There, Callan separates the water from sand and silt with an ingenious maze. The twists and turns in the maze slow the water down, so sediment drops out of suspension.
The 35-acre pond currently in use is surrounded by berms approximately 6-8 feet tall that contain the slurry. Callan has room at this same site to build another pond of approximately the same size. The two together will total 70 acres.
Bulldozers spread the sediment out in layers that allow excess water to drain out or evaporate. One dredging expert told me that when dry, the sediment will be hard enough to support foundations and homes.
Water that Doesn’t Evaporate Returns to the Lake
The pictures below track the movement of water within the placement area.
Comparison with December
To see how much progress Callan has made, compare the pictures above with the one below taken, just three weeks ago.
Beneficial Use
I wonder if that return channel will become a ready-made detention basin when the landowner develops the site. This is an ingenious example of “beneficial use” – turning a problem into a solution.
Up the Down Escalator
Nevertheless, there is a cost associated with dredging. Funding for the program comes from FEMA via U.S. Congressman Dan Crenshaw. The City will use money left over from previous West Fork Mouth Bar dredging. Crenshaw secured $125 million in federal funding to cover dredging, including phases already completed.
Some of the sediment shown above comes from natural erosion. Some also comes from upstream sand mining.
With 20 square miles of sand mines in a 20-mile reach of the West Fork between I-45 and US59, the average width of exposed sediment during floods is one mile.
In this case, we’ve failed to establish an effective regulatory regime based on a comprehensive set of best management practices for sand mines. And the public is paying the price in terms of increased flood risk and mitigation costs.
If you haven’t already written the TCEQ to register your concerns about their proposed (but inadequate) best management practices for sand mining, please do so. The public comment period ends on January 24. This post contains more about the problems with the TCEQ’s proposed BMPs. Texans for Responsible Aggregate Mining has even bigger concerns which I posted about yesterday.
Please mail your concerns to Jess Robinson, MC 175, Office of Legal Services, Texas Commission on Environmental Quality, P.O. Box 13087, Austin, Texas 78711-3087. Or you may submit them electronically. Comments must be received by 11:59 p.m. on January 24, 2025, and should reference “APO BMP List Proposal.”
So far, only a handful of people have registered public comments. So please help.

TRAM Pans TCEQ’s Mining BMPs, Proposes Improvements
1/14/25 – Texans for Responsible Aggregate Mining (TRAM) has issued a position paper that pans a new set of Best Management Practices (BMPs) for mining that the Texas Commission on Environmental Quality (TCEQ) has proposed. TRAM calls TCEQ’s BMPs “sparse,” “vague,” and “self-evident.”
TRAM asks everyone concerned about flooding and other issues related to aggregate mining to write the TCEQ before the close of public comments on the new BMPs. The deadline is January 24, 2025.
TRAM has also proposed a more comprehensive list of alternative BMPs that it believes will be more effective at minimizing disturbances created by mining.
TCEQ BMPs Fail to Address Legislature’s Requirements
Senate Bill 1 in the 2021 Legislative Session required TCEQ “to adopt and make accessible on the commission’s internet website best management practices for aggregate production operations regarding nuisance issues relating to dust, noise, and light…” But the BMPs ignore noise and light.
SB 1397 and House Bill (HB) 1505 in the 2023 Legislative Session then required TCEQ to adopt BMPs related to dust, water use, and water storage. But the proposed BMPs ignore water use.
TCEQ also ignored Texans for Responsible Aggregate Mining’s (TRAM’s) technical team of credentialed professionals. TRAM created a vetted list of BMPs and presented it to the TCEQ for consideration. Instead of drawing from that resource…
Description of TRAM Concerns
According to TRAM, TCEQ’s draft BMPs weaken TCEQ’s effort to protect public health and natural resources by “pretending to establish new guidelines while actually saying nothing. It is a disservice to taxpayers and to the environment.”
Sparse
In regard to sparse, TRAM says, “The proposed BMP list fails to address many of the real issues associated with APOs, including issues they were directly charged with addressing.”
“While they addressed dust and water storage (albeit inadequately) the TCEQ completely overlooked the “water use” portion of their 2023 charge.” And they still haven’t addressed noise and light pollution from 2021.
“TCEQ has simply failed to comply with their mandates,” says TRAM.
Vague
TRAM also feels that the TCEQ recommendations are “too vague to be useful.” For instance, “Ensure vehicles are driven at reasonable speeds to reduce dust disturbance.” TRAM suggests posting speed limits of 10 or 15 mph for unpaved haul roads. The group believes that the value of a BMP list is in detailing what a “reasonable speed” ought to be.
TRAM gave another example of vagueness. TCEQ proposed “Use fuel-efficient and appropriately-sized equipment to reduce emissions, operation time, and the overall amount of dust you produce.” TRAM questioned what “appropriately sized” meant.
“How is anyone to assess when a BMP is being implemented,” TRAM asked, “if they are described in completely subjective terms like ‘reasonable’ and ‘appropriate’?”
Self-Evident
TRAM also cited TCEQ recommendations that were self-evident. For instance, “Be sure your stockpiles are only as high as your permit allows,” or “The further dust-producing operations are from the site boundaries, the less likely they will be to create a nuisance for any neighbors.”
“Who benefits from these self-evident recommendations and simple reminders to follow the permit requirements?” asked TRAM.
“Completely Inadequate”
TRAM summed up its concerns in two words. “This completely inadequate draft BMP list, three years in the making, only weakens TCEQ’s effort to protect public health and natural resources by pretending to establish new guidelines while actually saying nothing. It is a disservice to taxpayers and to the environment.”
Whatever BMPs TCEQ ultimately settles on, they will neither be required nor incentivized. Still, TRAM believes it is paramount that the list be thorough and well vetted. That’s because, “It will serve to educate the public about what quarry operators could be doing to be good neighbors.”
Send Feedback to TCEQ Now
TRAM and its member organizations ask that you submit public comments to TCEQ at the address or website provided below by the January 24th deadline.
Mail comments to Jess Robinson, MC 175, Office of Legal Services, Texas Commission on Environmental Quality, P.O. Box 13087, Austin, Texas 78711-3087. Or you may submit them electronically. Comments must be received by 11:59 p.m. on January 24, 2025, and should reference “APO BMP List Proposal.”
TRAM suggests mentioning the inadequacies above. The group also suggests including BMPs from TRAM’s list that are most important to you. And insisting TCEQ addresses unaddressed issues required by the Texas Legislature: water use, noise, and light pollution.
More Complete List and Thorough Descriptions Needed
Further, they suggest addressing more issues more completely. For instance, some of the many BMPs that should be included are:
ReduceFlooding.Com Suggestion
ReduceFlooding.com agrees with all of TRAM’s recommendations, but given recent erosion, I would suggest that the minimum safe distance from rivers such as the East and West Forks of the San Jacinto, be 200 feet. Fifty feet can be wiped out in one flood.
