chartClover Leaf Solutions, Inc., is a leader in providing high-level industrial hygiene and safety services to Department of Energy (DOE) national laboratories and other federal clients.

We can provide our clients with an exceptional experience base in 10 CFR 851 occupational exposure assessments (OEAs) and hazards and controls inventories.

Clover Leaf has performed thousands of industrial hygiene hazards and controls inventory and OEAs in the DOE complex as required by 10 CFR 851 – Worker Safety and Health Program.

We have provided OEA needs to both DOE national laboratories in New Mexico (SNL and LANL) as early as 2006. No other small business has the DOE 10 CFR 851 experience in OEAs that we do.


sandiaRepresentative Projects at Sandia, LANL and DOE NTC
Site-wide Baseline OEA Project at Sandia National Laboratories

Clover Leaf supported the site-wide OEA Project at Sandia National Laboratories (SNL). A Clover Leaf CIH served as a Senior CIH team leader on the project, which was established to implement a comprehensive exposure assessment program per DOE Order 440.1A. The project consisted of the following:

  • Performance of OEAs in labs and facilities throughout SNL in order to assess potential worker exposure to chemical, biological and physical agents.
  • Evaluation of hazards and exposures, primarily for chemical hazards, noise, non-ionizing radiation, UV light, and confined spaces.
  • Training of other OEA project staff on SNL-specific systems.
  • Development of operating procedures for the OEA project.
  • Development of project report templates to facilitate consistency and quality among written reports for this project.

validationIndustrial Hygiene Verification & Validation Project

AA Validation and Verification (V&V) Sampling Project was performed as part of the SNL OEA Project. The use of sampling to evaluate exposure to heath hazards is required by DOE 10 CFR 851. V&V sampling was performed for a subset of activities that did not necessitate sampling during the assessment process (e.g., activities categorized as “acceptable” in the OEA rating process). This V&V Project allowed CIH professional judgment to be validated with quantitative sampling data. In addition, the V&V sampling project ensured that an adequate amount of activities were sampled during the OEA Project to satisfy DOE requirements. This was a highly successful project that provided quantitative defensible justification for the use of CIH professional judgment, which was an extremely important aspect of the baseline assessment process at SNL, a research & development environment.


LANL Baseline OEA Support

LANL_baseline_OEA_Clover_LeafClover Leaf supported the Baseline OEA project at LANL. The LANL site-wide OEA project was established to implement a baseline exposure assessment program per DOE 10 CFR 851. The project consisted of the following:

  • Performance of BEAs in laboratories and facilities throughout LANL in order to assess potential worker exposure to chemical, biological and physical agents.
  • Providing comprehensive IH Services, including identification and evaluation of hazards, monitoring of chemical substances and physical agents, and prescribed control measures.
  • Evaluation of hazards and exposures, primarily for chemical hazards, noise, non-ionizing radiation, UV light, and confined spaces.

This project required Q-cleared CIHs to comprehensively assess all IH-related hazards and controls associated with all activities at LANL. Clover Leaf provided five (5) Q-cleared CIHs with extensive BEA experience to support this project.


Contractor Assurance Office (CAO) Exposure Assessment Support

Clover Leaf performed a comprehensive audit of the LANL BEA Program with the LANL CAO. Clover Leaf was contracted by CAO to help ensure that the LANL BEA Program was consistent with the requirements from 10 CFR 851 and the American Industrial Hygiene Association (AIHA) strategy for BEAs. Clover Leaf was selected based on our extensive experience with performing BEAs as part of a long term year contract at Sandia National Laboratories. This project required Q-cleared CIHs to comprehensively assess all IH-related hazards and controls associated with all activities at LANL. Clover Leaf provided three (3) Q-cleared CIHs with extensive BEA experience to support this project.


Exposure Assessment Evaluation Process to Support Evaluation of LANL Subcontractors

Clover Leaf provided professional IH support to assess Subcontractor’s implementation of LANL Exhibit F submittals for IH. This involved evaluating IH Program documents, sampling strategies, sampling efforts, and developing corrective actions for identified inadequacies. This project supported a LANL ESH&Q oversight performance based initiative (PBI) to ensure subcontractors are implementing requirements of Exhibit F of their contracts related to workplace hazard assessments. LANL leveraged Clover Leaf’s extensive experience with BEAs at DOE facilities to accomplish this goal and close the PBI.


oeasBaseline OEAs, DOE National Training Center

Clover Leaf performed baseline OEAs of hazardous activities at the DOE National Training Center (NTC). This assessment provided the DOE NTC with an initial baseline assessment for compliance with DOE 10 CFR 851. These activities included personal air monitoring of the NTC Training Instructors and other maintenance personnel during live fire exercises, sandblasting and painting activities, welding operations, and bullet trap cleaning to assess potential exposures to workplace hazards.
