Summary of the Occurrence of Herbicide in Surface Water To Support Comments On USDA Draft Environmental Assessment

Caltha LLP Project Summary

Project: Summary of the Occurrence of Herbicide in Surface Water To Support Comments On USDA Draft Environmental Assessment
Client: Agricultural Chemical Manufacturer
Location(s): California, Illinois, Texas, Minnesota

Key Elements: Acquisition and review of state water quality monitoring data; statistical analysis of the occurrence and concentrations of herbicide in surface water, preparation and submittal of public comments to Department of Agriculture Draft Environmental Assessment

Overview: Caltha was contracted by this multinational agricultural chemical company to prepare a review and analysis of the occurrence of a specific common use herbicide, 2,4-D, in waters of the United States. Caltha first reviewed and summarized nationwide data in the US EPA STORET database and U.S Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program database. Caltha staff then contacted State agencies which implemented long-term Statewide water quality monitoring programs, including California, Texas, Illinois and Minnesota. All data were then compiled to provide a summary of 2,4-D concentrations in surface waters dating from the 1970s through 2012. Caltha then conducted a review of federal and state regulatory standards for 2,4-D in surface waters, including:
  • Federal Water Quality Criteria
  • State Water Quality Standards
  • Federal Safe Drinking Water Act Maximum Contaminant Level
  • Office of Pesticide Program Aquatic Life Benchmarks

Finally, Caltha conducted an analysis of the exceedance of applicable regulatory standards based on the comprehensive analysis of reported herbicide concentrations. All analyses were summarized in a report which was submitted to the US Department of Agriculture through its public comment process for a Draft Environmental Assessment document.

EPA Proposes Rule Requiring Electronic Submittal For NPDES Permit Information and Data

EPA is proposing rules that would require electronic reporting in place of the current paper-based NPDES reports. The proposed regulation would require permittees and regulators to use existing, available information technology to electronically report information and data related to the NPDES permit program in lieu of filing written reports. EPA believes the proposal will allow better allocation and use of limited program resources and enhance transparency and public accountability by providing regulatory agencies and the public with more timely, complete, accurate, and nationally-consistent sets of data about the NPDES program and potential sources of water pollution.

Given the large scope of the proposal, EPA has committed to publishing a supplemental notice should the agency receive comments on the proposed rule that require significant changes. EPA plans to publish the supplemental notice within 180 days after the public comment period for this proposed rule has closed. Comments on this proposed action must be received on or before October 28, 2013.

This proposed rule would require that reports submitted in writing now be submitted electronically by NPDES-permitted facilities to EPA through the National Environmental Information Exchange Network or to the authorized state, tribe, or territory NPDES program. This can include:
  • Discharge Monitoring Reports (DMRs),
  • Notices of Intent (NOI) to discharge in compliance with a general permit,
  • other general permit waivers,
  • certifications,
  • notices of termination (NOT) of coverage,
  • program reports

2006 NPDES Pestides Rule And Related Excemptions Removed

In response to a 2009 Sixth Circuit Court of Appeals ruling that vacated the 2006 NPDES Pesticides Rule, EPA has revised regulations to remove language added by the that rule. This language had exempted the application of pesticides from National Pollutant Discharge Elimination System (NPDES) permit requirements in two circumstances:
  1. When the application of the pesticide is made directly to waters of the United States to control pests that are present in the water, and
  2. when the application of the pesticide is made to control pests that are over, including near, waters of the United States.
The final rule removes this exemption and is effective on June 27, 2013.

Final Iowa Nutrient Reduction Strategy

The Iowa Department of Agriculture and Land Stewardship, Iowa Department of Natural Resources and Iowa State University have released the final Iowa Nutrient Reduction Strategy . The Iowa Department of Agriculture and Land Stewardship and Iowa Department of Natural Resources (DNR) worked with Iowa State University over a two-year period to develop a draft strategy that was released for public comment period on November 19, 2012. Over 1,700 written comments were received from November 19, 2012 to January 18, 2013.

The Iowa Nutrient Reduction Strategy is a science and technology-based approach to assess and reduce nutrients delivered to Iowa waterways and the Gulf of Mexico. The Iowa strategy was developed in response to the 2008 Gulf Hypoxia Action Plan that calls for the 12 states along the Mississippi River to develop strategies to reduce nutrient loading to the Gulf of Mexico. The strategy will be used to develop operational plans through the Water Resources Coordinating council. The strategy is designed to direct efforts to reduce nutrients in surface water from both point sources, such as wastewater treatment plants and industrial facilities, and nonpoint sources, including farm fields and urban areas, in a scientific, reasonable and cost effective manner.

New Standard Practice For Developing Lists of Invasive Plant Species

ASTM has announced that it has begun an initiative to create a standard that 1) describes the criteria and procedures by which to develop an invasive plant list for a defined region and 2) will be useful as the foundation for creating lists of invasive plants to support building codes and related applications. Model building codes and rating systems that aim to improve the environmental performance of buildings and their sites increasingly incorporate clauses to address the ecological damage related to invasive plants in landscaping.

ASTM believes a standard is needed to provide government agencies as well as environmental, academic, and horticultural organizations a common approach to determining what plants are invasive to a specified area. Existing State and Federal noxious weed lists have generally not kept pace with the latest science in the field, and many focus predominantly on agricultural, rather than ecological, impacts. Few local governments have yet to develop their own lists. With definitions dependent on the existence of local, State, and Federal lists, ASTM has concluded that the invasive plant requirements in green building codes will have little effect.

Keokuk, Iowa Receives Grant To Address Combined Sewer Overflows

EPA Region 7 has awarded $291,000 to the City of Keokuk, Iowa, for improvements to its sewer system. The project is expected to be completed by the fall of 2014. The purpose of the project is to construct new sanitary and storm sewer systems, which will eliminate four sewer overflows. The new sewer will provide adequate capacity for both current and anticipated future flows. A long-term strategy has been developed to eliminate six combined sewer overflows in Keokuk that drain either into the Mississippi River or Soap Creek.

Keokuk is one of 10 Iowa cities that have combined sewer systems. These systems typically use one pipe that combines sanitary sewer and storm sewer to the wastewater treatment plants during normal rainfall. However, during rainfall, this system sometimes overflows into nearby streams. and private partners.
