Mining BMPs Could Help Reduce Toxicity of Floodwaters

This is the sixth in a series on Sand Mining Best Management Practices (BMPs) proposed by the Texas Commission on Environmental Quality (TCEQ). BMPs help reduce erosion and prevent pollution, but these don’t address some important issues. Strengthening them could reduce both the magnitude and toxicity of future floods. By reducing the amount of excess […]

BMPs for Pre-Mining Phase of Sand Mining Can Help Prevent Erosion that Contributes to Flooding

According to best management practices (BMPs) being proposed by the TCEQ, pre-mining planning is one of the main ways to prevent sediment from leaving a mine. So much sand piled up in the San Jacinto after Hurricane Harvey that it reduced the conveyance of the river, contributed to flooding, and cost hundreds of millions of […]

Sand-Mine Structural Control BMPs Could Make Difference in Next Flood

In an effort to reduce sediment escaping into the San Jacinto River from sand mines, the Texas Commission on Environmental Quality (TCEQ) has issued Draft Guidelines on Best Management Practices (BMPs). Yesterday, I discussed vegetative controls for erosion. Today, I will discuss structural control. The two types often work together or in sequence. At the […]

How Vegetative Controls Can Help Sand Mines Reduce Erosion and Flooding

During Harvey, millions of cubic yards of sediment moved downstream. Some came from river bank erosion. But some also came from exposed sediment in sand mines that flank both sides of the West Fork like the one below. It’s exceedingly difficult to determine the percentages that came from various sources. Regardless, sediment built up at […]

We Must Strengthen Sand-Mining BMPs: Minimum Setbacks Just Part of Solution

At long last, the State of Texas could soon adopt minimum setbacks from rivers for sand mining. The Lake Houston Area Flood Prevention Initiative has been working with the Texas Aggregate and Concrete Association (TACA) and the Texas Commission on Environmental Quality (TCEQ) for two years to create a set of Best Management Practices (BMPs). […]

Comments Due to TCEQ on Sand-Mining BMPs by August 19

A couple weeks ago, I posted about rules governing the application of sand mining best management practices (BMPs). Now the Texas Commission on Environmental Quality (TCEQ) is accepting public comments on the BMPs themselves. Think of the difference this way: how/when to enforce guidelines vs the guidelines themselves. More than 90 people responded to the […]
