LRP News and Resources

The Land Restoration Program (LRP) News and Resources page was created to keep the public informed on updated news and related resources.

Fill Material and Soil Management​

​NEW!  The Fill Material and soil Management in Maryland Fact Sheet​ has been updated effective May 2022. On Wednesday June 15, 2022 the MDE-LRP held a virtual webinar and question/answer session to go over the updated Fact Sheet. The webinar discussed edits to this Fact Sheet with a focus on the Department's regulatory authority to ensure protection of public health and the environment and use of Confirmation Suitability forms. A link to a recording of the webinar can be found here (​Soil Reuse Webinar June 2022​).​​

Confirmation of Suitability Forms and Process Explanation Video can be accessed on the State of Maryland You Tube Channel.

Confirmation of Suitability (COS) forms may be used for the tracking of fill material and dredged material for reuse. The COS forms track the process from material supplier - to the transporter or interim receiving facility - through the end user. ​This is a voluntary process and is best suited for large scale soil reuse or dredged material reuse projects. There are 2 forms ​- The COS Fill Material Supplier form and the COS End User / Interim Receiving Site form. The flow chart explains the reuse process and indicates who signs the COS forms and at what step in the reuse process. MDE-LRP will seek cost recovery for staff time spent on project oversight. Projects are tracked through the CHS cost recovery process. MDE and the Maryland Port Administration will be holding a webinar to explain the COS and fill reuse process in the near future, date, and time to be determined. The COS forms can be completed electronically and submitted to MDE via email​ to ​​ Any questions regarding the COS process, applicability to new supplier sites, or sampling requirements can be directed to Jenny Herman at ​ or 410-537-3319. The Land and Materials Administration (LMA) has created this Fill Material and Soil Management fact sheet​ to assist property owners with the management and reuse of fill material and excess soils generated or used at properties under LMA oversight. This fact sheet is to be used in conjunction with the Voluntary Cleanup Program’s (VCP) Clean Imported Fill fact sheet and the innovative Reuse and Beneficial Use of Dredged Material Guidance Document. Please visit the Dredging and Dredged Material Management website page for more information.

Soil and ​​Groundwater Cleanup Standards ​

The Department has published an amendment to the MDE Cleanup Standards​ for Soil and Groundwater, October 2018 (Amendment #1, April 2022). The 2018 Cleanup Standards and 2022 amendment are located here (see link below).

Updated American Society For Testing And Materials (ASTM) Standard Practice For Environmental Site Assessments: Phase I Site Assessment Process

In accordance with §7-506(a)(1)(v)(1), all VCP applications must include a Phase I Environmental Site Assessment that follows the American Society for Testing and Materials (ASTM) E1527-13 standard. This standard was approved by ASTM International as the active standard on November 6, 2013.

Bioavailability of Arsenic

Effective July 17, 2013, the Land Restoration Program is adopting USEPA's recommendations for the default value for relative bioavailability of arsenic in soil. This decision was first described in USEPA’s Office of Solid Waste and Emergency Response (OSWER) Directive 9200.1-113 on December 31, 2012. This policy is based on the document entitled “Recommendations for Default Value for Relative Bioavailability of Arsenic in Soils.” In summary, the USEPA has determined that (1) the relative bioavailability (RBA) of arsenic in soils can be expected to be less than 100 percent; (2) the upper percentile of the data sets of arsenic RBAs in the United States result in a default RBA value of 60 percent; and (3) the default RBA for arsenic in soils should only be used if site-specific assessments for arsenic RBA are not feasible.

Additional LRP Resources


The ITRC is a national organization that consists of 50 states, the District of Columbia, multiple federal partners, industry participants, and other stakeholders, cooperating to break down barriers and reduce compliance costs, making it easier to use new technologies, and helping states maximize resources. ITRC brings together a diverse mix of environmental experts and stakeholders from both the public and private sectors to broaden and deepen technical knowledge and streamline the regulation of new environmental technologies. ITRC accomplishes its mission in two ways: it develops guidance documents and training courses to meet the needs of both regulators and environmental consultants, and it works with state representatives to ensure that ITRC products and services have maximum impact among state environmental agencies and technology users.

ITRC Training Link​

ITRC develops and delivers training courses via the Internet to reach a geographically dispersed audience of regulators, consultants, and other members of the environmental community. These courses create a unique forum for the exchange of technical and regulatory information because they are based on ITRC guidance documents, which reflect the consensus opinion of ITRC members from states and federal environmental agencies, the private sector, and citizen stakeholders.
