Best Management Practices
Recommends mines maintain a 1000-foot buffer from drinking water sources. Contains recommendations for erosion control, sediment control, stormwater management, vegetation and reclamation.
Pinal County requirements for obtaining a sand mine permit. They are notable for their emphasis on setbacks from rivers based on Flood and Erosion Hazard Zones. The latter are variable and defined by the potential for head cutting, pit depth, lateral migration of the river and pit capture. The document also contains several case studies documenting the damage to public health, safety and infrastructure from sand mining.
During storms, sand mines may discharge pollutants directly into nearby waterbodies, thereby degrading water quality. In 1990, the U.S. Environmental Protection Agency (EPA) developed permitting regulations under the National Pollutant Discharge Elimination System (NPDES) to control stormwater discharges. As a result, NPDES permitting authorities, which may be either EPA or a state environmental agency, issue stormwater permits to control runoff. This is a fact sheet on the program which includes a list of best management practices.
Compendium of Best Management Practices To Control Polluted Runoff. Chapter 5 addresses mining activities. Joan Meitl and Todd Maguire, Editors
The gold standard among these types of publications for clarity. Contains a balanced discussion on the benefits of sand mining, the uses of sand, a glossary, and a primer on how sand mines operate. The heart of the document though is a well illustrated discussion of sand mining best practices and why they are necessary. Easy for the non-technical public to understand. Covers all aspects from site selection to clearing, construction, operation and abandonment. Explains how best practices can mitigate the dangers of sedimentation in rivers. Focused on sand mining in flood plains.
Note the first line: A sand and gravel pit shall be located in area that precludes pit capture. Pit capture occurs when a natural buffer separating a pit from a Scenic River is breached by streambank erosion, channel migration or overflowing floodwaters.
Describes limitations of water discharges from concrete, aggregate and asphalt operations in Louisiana.
Focuses on best practices for industrial sites and pollution prevention plans for stormwater runoff. Not specific to mining, but contains in-depth discussion of principles that apply to mine sites. Also contains a glossary of acronyms and definitions, and a reference section with links to additional resources.

Guidelines for operators of sand and gravel mines operating in Oklahoma waterways. Discusses operations within the context of Section 404 of the Clean Water Act. Section S2 specifies, “No dewatering piles or stockpiles shall be positioned within the banks of the channel below the Ordinary High Water Mark (OHWM).” S3 specifies, “Dredging shall not be conducted in a manner or to such depths that induces channel shifts in the river or streambed, or aggravates erosion along the banks.” E3 discusses the crossing of waterways with equipment. E5 specifies that “Push piles and loading piles remaining at the end of the week shall be redistributed across the work area, to leave no obstruction to or disruption of flows in case the river or stream rises.” E9 specifies that “The operator shall anticipate river or stream rises based on storms within the watershed, and shall: 1) immediately haul or redistribute remaining short-term working piles and 2) restore natural grade and appearance to the work area(s).

A cautionary tale of practices that led to the banning of sand mining. Also discusses the use of crushed basalt as an alternative to sand.
Donnybrook Sand Mine Case from Environmental Law/Australia. A sand mine was proposed on a floodplain in South East Queensland, adjacent to a wetland area. A principal issue in the court case was the potential environmental impacts of the mine. The soil chemistry of the site, containing acid sulphate soils and heavy metals such as iron, and the complex hydrology of the area created a cocktail of potential ecological impacts.

Sand mining effects, causes and concerns: A case study from Bestari Jaya, Selangor, Peninsular Malaysia. By Muhammad Aqeel Ashraf1, Mohd. Jamil Maah, Ismail Yusoff, Abdul Wajid and Karamat Mahmood. From abstract: “The assessment of water quality shows that water has been highly polluted immediately downstream of station at Selangor River due to high concentrations of suspended particles. Transport modeling and water quality analyses performed have identified major physical environmental impacts. The issue poses a number of policy questions that are worth to be implemented by the government.”
High-level overview of physical, water quality, and ecological impacts of sand mining in rivers when unregulated. Note: The sand mining along the San Jacinto is in flood plains, not the river. This is included because some people now want miners to remove material from the river as a way to reduce dredging costs.

Requirements for obtaining a nationwide permit. Best Management Practices required by the state can be found at the end of this letter to the U.S. Army Corps of Engineers.
Too confusing to summarize, but note the highlighted section regarding notifying the TCEQ about discharges during force majeure events. According to State Representative Dan Huberty, the TCEQ received no such notifications. And the TCEQ certainly not disclose any to me when I filed a complaint.
Includes requirements to control erosion and sedimentation at the site. Take a look at page 63. The permit does not require the installation of a particular BMP in most cases; the permit requirement is that certain BMPs be evaluated for effectiveness and the most effective installed and maintained.
…and other materials in Texas waterways.
History, scope and protections offered by Texas Parks and Wildlife permitting program. Focuses on mining in rivers and streams, as opposed to floodplains.
The primary purpose of this document is to supplement the Best Management Practices section of the Texas Nonpoint Source Pollution Assessment Report and Management Program by providing further information about the BMPs addressed there. This document provides detailed descriptions and implementation considerations for the various alternate BMP names and categories, as well as references to still more detailed technical guidance and specification documents addressing these BMPs. Because there is a lack of standardized terms for NPS BMPs, this document provides extensive cross-references to help the reader identify BMPs of interest by any of their various names and to compare related practices.
TCEQ rules regulate the location of quarries along a portion of the Brazos called the John Graves Scenic Riverway. They use the 100-year flood plain as a buffer zone between mines and the river. However, according to a TCEQ researcher, in other parts of the state, there seem to be:
- No rules that include a setback distance from a sand mine to the San Jacinto River.
- No restrictions on TCEQ permitting of sand mines in flood prone areas.
Background on Formation of John Graves Scenic Riverway on the Brazos. Explains why TCEQ rules and regulations are different there. It was formed as a pilot program to reduce sedimentation from sand quarries.
These are the local standards that sand mines must meet to obtain permits for operating in flood plains and floodways. Violations include fines and revocation of permits. Among the regulations: a prohibition against sending material downstream that harms adjacent communities or which causes other governments to increase costs, such as dredging. See highlighted portions of text.
National laws and regulations apply within Texas boundaries:
- See the Clean Water Act.
- EPA BMP guide specific to Sector J (Mining and Processing) facilities that includes sand mines. See more detailed description above under EPA in Best Management Practices.

Sand Mine Real Estate Tax Appraisals
Surveys of 53 parcels of land being used as sand mines on the East Fork and West Fork of the San Jacinto showed that not one was appraised as a sand mine (Classification G3) according to State of Texas guidelines. Dozens were classified as ag/timber land or vacant rural land and, as a consequence paid very little tax.
