Water Resources Project

Non-Metallic Mineral Mining Support

Mid-Atlantic Location

Solution Overview

Client:

A national mining company

Business Challenge:

In preparation for future cessation of mining at the site, the client needed support in reclamation and implementation activities, including the construction of a multi-billion gallon reservoir to support future water needs for the growing population of the Mid‑Atlantic coast.

Solution:

Apex assisted with this 10 plus year project from planning, permitting, engineering, and implementation.

Results:

  • Compensatory Mitigation was negotiated and purchased.
  • Onsite reforestation saved the client significant time and expense.
  • Stream rerouting and LID features are proving very successful.
  • Positive feedback has been received on the results of the plans and monitoring.

Challenge

In preparation for future cessation of mining at the site, the client needed support in reclamation and implementation activities, including the construction of a multi‑billion gallon reservoir to support future water needs for the growing population of the Mid‑Atlantic coast.

Solution

Apex assisted a national mining company with a 10 plus year project from planning, permitting, engineering, and implementation. The following is a brief outline of some of the activities that occurred to plan for the future cessation of mining at the site, the creation of a multi-billion gallon reservoir with infrastructure, and reclaiming the site to plan for the future water needs of the growing populations centers along the Mid‑Atlantic coast.

Planning

  • Fatal Flaw Analysis (Phase I ESA, T&E, Historic Resources, Pre-Application Meetings, etc.)
  • Preliminary Engineering Plans and Discussion with Locality, DMM, and other regulatory agencies

Permitting

  • Delineation of Waters of the U.S. (500+ acre properties)
  • Stream Assessments and Pereniality Determination for onsite streams
  • Survey for Small Whorled Pogonia (Isotria medeoloides)
  • Section 404/401 Permit for Impacts to Waters of the U.S. and Compensation Plan
  • Total Maximum Daily Load (TMDL) Water Quality Impact Assessment and Compensation Plan
  • Nutrient Evaluation and Reduction Plan
  • Environmental Quality Corridor (EQC) Assessment and Compensation Plan

Engineering

  • Dual Pit design to route certain flows around the pits while having the ability to eventually turn flows into the pit for the creation of a multi-stage reservoir with billions of gallons of storage
  • Low Impact Development Features (floating wetland treatment islands, bio-retention swales, large grasses lines swales for bypass and infiltration)
  • Nutrient Analysis of EQC and other buffers to be removed versus areas to be restored
  • EQC and other buffers Restoration Plan and Habitat Evaluations Procedures (HEP) modeling

Implementation

  • Specifications, Bid Requests and Review
  • E&S and 404/401 monitoring
  • Coordination of Compensatory wetland and stream credit purchases
  • Rerouting a stream, and establishing LID features
  • Construction Monitoring
  • Meetings with Agencies

Results

  • Compensatory Mitigation was negotiated and purchased, where the client saves a considerable amount due to pre-purchase agreements in a volatile credit market where credits are become more and more scarce
  • Buffer replanting was completed, and monitoring is showing success and growth of the trees, where the onsite reforestation saved the client significant time and expense
  • Rerouting a stream and LID features are installed and proving very successful
  • Agencies are providing positive feedback on the results of the plans and the monitoring
