Overview of Remedial Design Process u Definition of RD u Various leads may undertake RD u Key components of RD 32

Scoping u RD begins with project planning u Scoping the RD involves several planning activities » Establish the TRT » Coordinate activities with the state » Collect predesign information » Prepare the project management plan » Identify constraints on the project 33

Tasking the Designer u Determination of the lead u RPM’s role » Fund-lead » Enforcement-lead » USACE-lead » State-lead » Federal facility-lead u Using standard tasks 34

Predesign Submittals and Treatability Studies u Standard submittals before field work begins » SMP » HASP » ERP » FSP » QAPP u Treatability studies may be performed if necessary 35

Design Submittals: Preliminary Design Phase u Design is 30 percent complete u Components of the preliminary design » Design criteria report » Basis of design report » Preliminary drawings and specifications » Results of value engineering screening » Preliminary RA schedule » Preliminary RA and O&M cost estimates u Review of preliminary design submittals 36

Design Submittals: Intermediate Design Phase u Design is 60 percent completed u Optional phase u Includes revision of deliverables u Focus of review » ROD requirements » Biddability, constructability, operability » Pollution controls » Construction practices » Accuracy of calculation 37

Value Engineering u A specialized cost-control technique u VE screening identifies potentially high-cost design u VE study performed concurrent with design elements 38

Prefinal and Final Design u Incorporates final comments into the design submittal u Final design must be certified by a licensed professional engineer u Components of the prefinal and final designs 39

Post-design Activities u RA solicitation u Fund-lead requirements » Obtain SSC » Secure access to the site » Develop an RA assignment for Fund-lead RAs u PRP-lead requirements u Federal facility-lead requirements 40

The RA Process u RPM’s role u RA planning activities u Procurement of RA contractor u Preconstruction activities and RA submittals u Construction u Completion activities 41

Key Personnel in the RA u RPM u TRT u Oversight contractor u RA contractor u Resident engineer or construction manager u Construction contractor’s supervisor 42

RA Implementation: Routine Activities u Health and safety issues must be monitored u Inspection and testing in accordance with the QA plan u RA schedule used to monitor progress u Progress is documented in various logs and reports » On-site » Progress reports » Daily field logs 43

RA Implementation: Near Completion Activities u Prefinal construction conference held as each OU nears completion u Prefinal inspection performed to identify deficiencies u Final inspection ensures work is complete u Settlement agreement reviewed at PRP-lead sites 44

Value Engineering During Construction u VE is required by contracts u RPM reviews the VE change proposal 45

RA Implementation: Demobilization u Demobilization tasks: » Removal of material » Cleanup of debris » Disconnection of utilities » Completion of restoration or replacement » Transfer of equipment and property » Transfer of documents 46

RA Implementation: Remedial Action Report u Prepared by the remedial action contractor 60 days after the final inspection u Reviewed by the RPM u Project completion report completed for PRP- lead sites 47

Overview of O&M and Post Construction Activities u O&M begins when remedy is operational and functional u Site closeout documents cleanup milestones u Five-year reviews conducted at certain remedies to ensure protectiveness 48

Operation and Maintenance u O&M activities include maintenance of treatment systems and final covers, monitoring of groundwater, and implementation of ICs u O&M activities are initiated after determination that the remedy is operational and functional (O&F) u O&M is funded, implemented and sustained by states or PRPs » LTRA for groundwater and surface water restoration u RPM responsibilities include oversight, optimization, and documentation of O&M activities 49

Major Milestones in the Closeout of NPL Sites Under CERCLA u Remedial action completion u Construction completion u Site deletion 50

RA Completion for an OU u Occurs when the designated EPA regional official approves the Interim or Final RA report u Will require a separate RA completion for each phase if the OU is implemented in phases u Will vary for different remedies » Excavation and off-site disposal » On-site treatment of wastes (other than groundwater or surface water restoration) » Containment » Groundwater and surface water restoration involving active treatment » Groundwater and surface water restoration involving MNA 51

Construction Completion u Means that all physical construction (under removal or remedial authority) is complete at the entire site u Has no legal or financial significance u Is achieved when the designated regional official signs the PCOR or FCOR and EPA HQs concurs u Applies only to sites on the final NPL 52

Site Completion u Signifies the end of all response actions at NPL sites u Must meet specific criteria u Requires an FCOR for documentation u Enables site to be eligible for site deletion 53

Site Deletion u NCP requirements dictate the deletion process u NPL deletion criteria in § 300. 425(e) u Sites in O&M may be deleted u NPL deletion through RCRA deferrals u The deletion process 54

Partial Deletion u Partial Deletion Rule and NCP requirements dictate the process u Partial deletion process is similar to full deletion, except for: » Mapping requirements » Documentation requirements 55

Five-Year Reviews u Statutory requirement for five-year review u Purpose of five-year review u Five-year review process u Site deletion is independent and unaffected by the fiveyear review requirement 56

Records Management u Promotes efficiency in compiling and retrieving Superfund information u Ensures that document storage space is adequate and secure u Promotes compliance with relevant laws and regulations 57

Roles and Responsibilities in Records Management u Role of HQ: Overall program goal setting and oversight u Role of regional records manager: Day-to-day management of the system u Role of RPM: Provision of latest site-specific documentation u Role of records center staff: Day-to-day support of the system 58

Types of Records and Files to be Maintained u Site files u AR u Litigation support documentation u Cost documentation u Documentation of damage to natural resources 59

In Review u Remedial actions at NPL sites are designed to provide permanent solutions from the release of hazardous substances u CERCLA establishes goals and management principles for remedial actions u Remedial actions generally involve six major phases u The RPM is responsible for directing and coordinating the remedial process 60
