water quality

  • The Clean Water Act (CWA) is the main federal regulatory framework we have for protecting the quality of water in the United States. The CWA delegates authority to the states to monitor and regulate pollution in our rivers, streams, lakes, and wetlands. One of the greatest ironies in Missouri is that despite having great pride in our rivers and being host to some of the best recreational water activities in the country, we are woefully behind on implementing the law.  See below for an interactive timeline that explains some of the most significant developments for clean water protection in Missouri—use the arrows at the sides of the timeline to move forward through the events.   Keep reading below the timeline for more information about current issues and to learn about what MCE is doing further the interests of all Missourians who care about clean water.

     

    Unclassified Waters

    The first step in implementing the Clean Water Act is for states to classify their waters. After rivers, streams, lakes, and wetlands are classified, they are assigned Water Quality Standards appropriate for their classifications based on the uses they are designated. The goal of the Clean Water Act was go have all waters of the U.S. attain fishable/swimmable uses by 1983. Fishable/swimmable is shorthand for having the capacity to support aquatic life and being safe for full-body human contact with the water. Missouri has not assigned default fishable/swimmable uses to its waters and, as a result, there are not applied Water Quality Standards on many of our state's waters. 

    What are unclassified waters and why are they important?

    A substantial number of Missouri's stream miles have never been classified, meaning at least 65,000 miles of stream receive inadequate protection from water pollution under Missouri's water quality laws. Unclassified streams are generally smaller than Missouri's larger, classified water bodies, but their protection is equally important—the connections between smaller streams and wetlands to larger waters have real effects on rivers, lakes, reservoirs, and estuaries (see EPA's Connectivity Report (2015)). Missouri's smaller streams are critical parts of our large river systems. They serve as feeder streams for our big rivers and as nursuries for young fish. When they are not healthy, our bigger rivers are negatively impacted.

    Missouri's unclassified waters are not even receiving the minimal protections required by the Clean Water Act. These waters should be safe to swim in and be habitable for aquatic life. Pollutant discharge permits should not be authorized in unclassified waters. More than forty years after passage of the Clean Water Act, Missouri still fails to comply with the law.

    What is MCE doing ?

    The classification of a water body gives it needed protection from pollution. The Coalition urges Missouri's Department of Natural Resources to take the next steps in protecting our vital aquatic resources by classifying our waters. Simultaneously, MCE encourages the U.S. EPA to demand DNR classify its waters or else classify them for us—exactly as directed by the Clean Water Act.  Learn more about MCE's actions surrounding unclassified waters

    Polluted Waters

    Too polluted to drink, too polluted to fish or swim in, or even too polluted to support healthy aquaitc life, waters that have suffered from the byproducts and runoff of industry and agriculture are listed as "impaired". Section 305(b) of the Clean Water Act requires each state to report on the status of the waters of the state. Every two years, each state is supposed to list all its streams and lakes that fail to meet water quality standards along with the pollutants causing the impairments. The list, known as the "303(d) list", is intended to spur states to develop and implement plans to address the impairments. 

    What is MCE doing ?

    We monitor the 303(d) list when it comes out every two years and work to extend Water Quality Standards to all waters of the United States. MCE watchdogs the implementation of Total Maximum Daily Loads and National Pollution Discharge Elimination System (NPDES) permitting in the state.Read more about impaired waters in Missouri

    Water Quality Standards

    After waters are determined to be impaired, Water Quality Standards (WQS) are applied to these classfied waters. Standards are the benchmark for ensuring water quality sufficient to meet the use of swimming, supporting aquatic life, sourcing drinking water, or other purposes assigned to a particular body of water.

    What is MCE doing ?

    MCE advocates for the classification of all waters of the state as, at a minimuim, both fishable and swimmable as required by the Clean Water Act and WQS that support those uses. MCE participates in DNR stakeholder workgroups, watchdogs the implemenation of WQS requirements, and collaborates with EPA, DNR, and others to support effective water quality management in Missouri. Read more about the characteristics of Missouri's Water Quality Standards

    Nutrient Reduction

    Nutrient pollution is a major contributor to contaminated drinking water, fish kills and the Dead Zone in the Gulf of Mexico. Numeric nutrient criteria are a critical tool for protecting and restoring the designated uses of a waterbody with regard to nitrogen and phosphorus pollution. These criteria enable effective monitoring of a water body for attaining its designated uses, facilitate formulation of NPDES discharge permits, and simplify development of total maximum daily loads (TMDL) for restoring waters currently not attaining their designated uses (i.e. impaired waters).

    What is MCE doing ?

    MCE works within MDNR stakeholder workgroups to push for the development of numeric nutrient criteria on lakes, resevoirs, rivers, and streams. EPA must approve states' nutrient criteria proposals. EPA disapproved Missouri's lake nutrient criteria in 2011. Since that time, Missouri has repeatedly produced revised criteria to address EPA's disapproval. Each time, agricultural interests stop the process. We will continue to advocate for revised criteria at the state level, but it may be up to EPA to enforce the law. 

    MCE is also part of a stakeholder group working on developing a water quality trading (WQT) program in the state of Missouri. Learn more about water quality trading here.

    Wetland and Stream Impacts of Development

    The Clean Water Act allows for project development that impacts our water resources when that project is authorized by the Army Corps of Engineers and follows specific requirements (outlined in Section 404 of the CWA). Permit applicants must demonstrate public benefit from the construction of the project; lack of alternative options for development site; the minimization of impacts to water resources; protection of endangered and threatened species; and requirements to offset these impacts through restoration, enhancement, and preservation of wetland and stream resources in the same watershed as the proposed project. 

    What is MCE doing?

    We closely monitor project permit applications that propose to impact Missouri's waters. We submit formal, public comments promoting real and measureable ecosystem benefits in mitigation activities and enforcement of the application requirements. MCE watchdogs the implementation process of 404 permit application, mitigation, and program monitoring to advocate for Missouri citizens' right to healthy water resources. Check out an interactive map of section 404 permitted projects in your watershed

    Clean Water Protection Rule (WOTUS)

    After decades of confusion regarding the interpretation of the phrase "Waters of the United States" (WOTUS), EPA and the Corps of Engineers created a rule clarifying very specifically what constituted jurisdictional waters. On May 27, 2015, EPA released the final rule set to go into effect on August 28.  Thirteen states, including Missouri, filed an injunction to stop the rule citing undue harm to regulated entities—most prominently, corporate agriculture—and later, on October 9,the Sixth Circuit Court of Appleals in Cincinnati issued a temporary stay of the rule delaying much-needed protections. While maintaining the agricultural exemptions in the former rule, the Clean Water Protection Rule will ensure that waters protected under the CWA are more precisely defined, more predictably determined, and easier for businesses and industry to understand. Learn more about the Rule from the EPA

    What is MCE doing?

    MCE continues to support the EPA and Corps of Engineers' development of a clarified definition of "Waters of the U.S." in the Clean Water Act. We rally our members to support the agencies' rulemaking and we continue to oppose legislative attacks on its implementation. 

     

     

  • TAKE ACTION - Citizens should have a voice in protecting our waters. 

    Factory Farms are undermining our rights to clean water and air. The Clean Water Commission is a 7-member citizens' board which holds the authority in Missouri to implement the federal Clean Water Act and Missouri Clean Water Law and certify factory farm permits. A new state law (HB 1713) has removed the legal requirement for public representation on this Commission. While no longer required, the governor can choose to appoint members of the public to this important commission instead of special interests such as the concentrated corporate agriculture industry.

  • The Clean Water Act (303(c)(2)(a)) states "water quality standards shall serve the purposes of the [Act] and consider the use and value for public water supplies, propagation of fish and wildlife, recreational, agricultural, industrial and other purposes, and … navigation". The CWA requires states to develop Water Quality Standards (WQS) for all classified waters. Water quality criteria—narrative and numeric—is developed and assigned to water bodies based on the use assigned at classification. 

    Initially proposed in September of 2013 and undergoing the public review process, EPA's final updates to the National Water Quality Standards regulation were published in the Federal Register on August 21, 2015. The updated regulation is intended to "provide a better-defined pathway for states and authorized tribes to improve water quality and protect high quality waters".  Look at a fact sheet explaining the Final Rule

    Under the CWA, water bodies are initially classified by the states and a protection level is determined based on the goal use for the water body— a few examples of goal uses are fishing, swimming, or sourcing drinking water. Next, a water quality assessment of water bodies determines which waters are impaired and sets priorities for improvement. Permit limits for point source dischargers are set through the National Pollutant Discharge Elimination System (NPDES) and are based on the water quality standards.  Water quality standards are also used to determine Total Maximum Daily Loads (TMDL) in impaired systems.

    Components of Water Quality Standards regulation include requirements for:

    • Designated Uses – uses specified in WQS regulation whether or not they are being attainedconsidered to determine the necessary criteria needed to protect the use
    • Water Quality Criteria – states adopt numeric and narrative criteria, and chemical-specific criteria to protect designated uses including: biological criteria (a description of the desired aquatic community), nutrient criteria (nutrient limits to protect against over-enrichment and cultural eutrophication), and sediment criteria
    • Triennial Review – states must review WQS every three years
    • Antidegradation  –  identified high quality waters require enhanced protection to avoid degrading pristine resources
    • WQS Variances – a tool to help states or tribes meet compliance requriements and help ensure progress toward improving water quality is achieved by temporarily relaxing WQS
    • Use Attainability Analyses (UAA) – all water uses are assumed to be swimmable/fishable unless documentation through a UAA shows those uses are unattainable

    In Missouri

    Missouri has not classified all its waters—an inaction that renders our state out of compliance with the federal Clean Water Act of 1972. Currently, designated uses have been assigned to the classified waters visible on a 1:100K map (1 inch on the map: 100,000 inches on the ground). Through its Water Protection Program, the state Department of Natural Resources (DNR) assigns designated uses and associated water quality standards to those classified waters. Criteria are set based on uses.  Examples of regulated pollutants include chlorine, chloride, fluoride, nitrate, dissolved oxygen (minimum), oil and grease, and E. coli. See information from MDNR on Missouri's Water Quality Criteria

    Unclassified waters are not legally protected from regulated levels of these and other pollutants that ensure a minimum level of water quality is preserved in our waters.  MCE participates in stakeholder Water Quality Standards workgroups to advance water protections in the state. Check out our information on Missouri's unprotected waters

    Nutrient pollution (primarily nitrogen and phosphorus) is particularly abundant in Missouri rivers, lakes, streams, and wetlands due to industrial discharges, agricultural runoff from fertilizer application, and stormwater runoff from urban areas. Nutrient pollution is a major cause of the Dead Zone in the Gulf of Mexico. Numeric nutrient criteria has not been established for any classification of water bodies in Missouri. In 2011, EPA denied DNR's proposed numeric nutrient criteria for lakes. DNR workgroups have developed draft criteria several times since EPA's disapproval, but political interests have stopped the process. DNR proposed its latest draft in October 2015. MCE participates in DNR's Nutrient Criteria Technical Subcommittee.

     

     

     

     

     

     

  • Everyone lives in a watershed

    Image created by: Joe Mohr Toons, joemohrtoons.com

    What is a watershed? Why is what we do on land crucial to clean water?

     
    A watershed includes all of the life-sustaining connections and interconnection that provide us with clean, useable water. The most fundamental of these connections is the mutual relationship between land and water.  Every land area drains into a water source which means land activities are inextricably tied to the health and quality of our water supply. Also known as a "drainage basin" or "catchment" - a watershed is the area of land that drains into a river, wetland, or creek from the land surrounding it. The land in every watershed is drained by creeks and streams- each with its own small watershed - land draining to it. Collectively, the waters merge into the larger watershed of a river. Small or large, all watersheds share similarities in form and function, and each watershed is ecologically unique. 

    The connection between water and land connect human beings' activities to the health of our water resources. Animals and plant life all impact their immediate environment, but the fluid, mobile nature of water introduces the complexity of movement. The impacts of these activities include the introduction of pollutants and sediment literally carried by surface and underground flow to the next lowest point on and on until discharging into bigger rivers and ultimately, the ocean. 

    Be a WATERSHED WARRIOR!! Take the pledge to reduce your impact and improve the health of your watershed.

     

    Watershed Projects and Resources:

    Check out Watershed Cairns to see art connect with water! Cairns are stracks of rocks used to demarcate trails. These beautiful glass sculptures are displayed in places of signifcance to watershed functioning in outdoor locations in Illinois and Missouri. The locations denote areas where land collects water - places that conduct water to creeks, streams, and rivers to ultimately arrive in the Mississippi River. The Cairns are photographed and removed due to their fragility. See the Watershed Cairns website here.

    The Our Missouri Waters Initiative is a Missouri Department of Natural Resources effort to engage citizens and sound science to develop watershed-specific strategies to collaborate on common goals to address challenges in each basin. 

    MCE's involvement in the Kiefer Creek Watershed began in 2009 when dogs were becoming ill after coming in contact with the creek in Castlewood State Park. Thus began the Kiefer Creek Watershed Restroation Project. The long term project engaged local watershed residents in the development of a watershed management plan to address bacteria (e.Coli) and chloride pollution impairing the water supply.

     

  • We encourage you to explore the map to learn the landscape of factory livestock farms in Missouri and Illinois. The map’s icons are coded according to species and operation size. Additional information about and an image of each facility is available in the pop up boxes after clicking on the icon. Additional information about data sources and methods for the map’s development are available below it.

     

    How to use the map:

     
      The Legend:

    In the Legend panel to the left of the map, you can view the icons representing confined animal feeding operations in Missouri and Illinois on the map. The animal type represents the species produced for slaughter and sale at the facilities while the size of the animal icon denotes whether it is a Class I or II Concentrated Animal Feeding Operation (CAFO), a designation based on number of “animal units” (explained more fully in the Data Resources section below the map). Some counties are also color coded if they have a county-level protection - such as a health or zoning ordinance - in efforts to decrease the health and environmental impacts of industrial factory farms locally.     

     
      The Map Layers:

    The map contains different ‘layers’ of data that the user can select to display and hide while navigating the map content. To see more or less information displayed, select Layers to the left of the map above the list of species icons. Layers on the map can then be turned "on" and "off" by selecting and deselecting the checkboxes next to each.

      Search Function:

    In the toolbar at the top of the map, you can search for a place or location. Select the spyglass. This will allow you to search for specific CAFOs of interest. You could also search for an address to see CAFOs nearby.

     

    What is a CAFO?

    Confined Animal Feeding Operations (CAFOs) or more commonly - factory farms - are enclosed warehouse-type structures or barns in which animals are bred and contained while they produce dairy and eggs or until slaughter for meat. There can be tens of thousands of animals (depending on the species size) contained in these type of warehouses for most of all of their lives.

    According to DNR: "In just the past 20 years, there has been dramatic change in animal agricultural production in Missouri and the United States.  These changes have included a significant increase in the overall size of individual operations, an increase in the number of animals raised per operation and a shift towards raising poultry and certain livestock within production barns.  Concentrated animal feeding operations, frequently referred to as CAFOs, are large animal agricultural facilities that raise a specific number of animals in production barns or confinement pens." Read more about CAFO Class sizes below the map.

    Example Class 1A CAFO:                                                                                                             Example Class 2 CAFO:

     

    We should care about this dramatic shift in meat production for numerous reasons. CAFOs pose threats to human health - both from meat consumption as well as environmental contaminants in the facilities' immediate vicinity, pollute waterways, and contribute substantially to the greenhouse gas emissions that cause climate change. Read more about these threats.

     

    Data Sources

    Missouri CAFO data: 2012 National Pollutant Discharge Elimination System (NPDES) Permit list from Missouri Department of Agriculture and 2016 list of current CAFO sites with operating permits

    Illinois CAFO data: All CAFO inventory maintained by Illinois Environmental Protection Agency as of March 2016

    ​Missouri County and Township Restrictions on AFOs: University of Missouri Extension, Nutrient Management Resources for Planners, Missouri County and Township Restrictions on AFOs, http://nmplanner.missouri.edu/regulations/mocountyrules/ (last updated August 2007). 

     

    NPDES vs. Operating Permits

    NPDES permits are no longer required, so many CAFOs only have an operating permit. Some CAFOs that were on the 2012 list are not on the 2016. We noticed looking at the 2012 NPDES Permit list for Missouri and the 2016 operating permit list for Missouri that  list. This means those CAFOs may no longer be in operation. However, CAFOs can still pose threats to the environment and the rural community in which they stand even when they are closed down. Therefore, we kept those CAFOs that had 2012 NPDES permits on this map even if they were not on the 2016 operating permit list.

     

    Class Sizes

    CAFOs are categorized by class size. There are two broad classes, Class I and Class II, and Class I has three subcategories: Classes IA, IB, and IC. A CAFO is classified based on the number of animal units contained within it. Animal units are not the same as total animals. Animal units and Class sizes are explained in the images below.

     

    For more information on class sizes, animal units, and other useful information, check out MO DNR’s Guide to Animal Feeding Operations.

     

    CAFO Addresses

    In instances in which MO DNR’s CAFO data listed business addresses instead of true CAFO location addresses, the location of the CAFO facility was determined by cross referencing DNR’s map of CAFOs with NPDES permits. After finding the true location on DNR’s map, we then went to Google Earth and captured an image of each CAFO’s physical location. These images can be viewed in the pop-up boxes that appear when you click on the CAFO icons on the map. If you click on the image in the pop-up box, it will take you to a new tab with a larger view of the Google Earth image.

     

    What looks different between the MO and IL CAFOs?

    In Missouri, we were able to separate out egg layer CAFOs from the other poultry CAFOs based on more specific information provided by DNR about which types of poultry are in each poultry CAFO. This information was not made available to us by IL EPA. Therefore, you will see that Missouri has an additional species “egg layer.” This does not mean that Illinois does not have egg layer CAFOs, we simply do not have information to inform us which poultry CAFOs are egg layers in Illinois.
