Risk Assessments and Remediation
Ninyo & Moore has developed its Risk Assessment program to define and quantify
the risk of hazardous substances to human health and the environment in accordance
with EPA’s Risk Assessment Guidance for Superfund, California Department
of Toxic Substances Control (DTSC) guidelines, and other accepted risk models.
Remedial Investigation / Feasibility Study (RI/FS)
The purpose of an RI/FS is to further refine site and contamination characteristics
with respect to designing and implementing an appropriate remedial action. The
RI/FS work scope will vary significantly according to the specific site characteristics.
Project team personnel are familiar with performing RI/FSs to assist our clients
in selecting cost effective and technically sound remedial alternatives.
Remedial Action Planning and Remedial Action Design
To meet our client’s needs for meaningful remediation cost and effective
remediation activities, Ninyo & Moore develops and prepares Remedial Action
Plans (RAPs) for regulatory approval. RAPs are often supplemented with Remedial
Action Designs (RADs) for cost estimating, contractor bidding, and permitting.
On those sites for which our clients decide to undertake remediation, Ninyo & Moore
will implement the RAP/RAD by hands-on remediation using its own staff and management
or a number of appropriate specialty subcontractors.
