Environmental Consulting for Complex Projects
TULLOCH’s ecologists, biologists, engineers, geologists, and environmental specialists help public and private sector clients navigate regulatory obligations, understand site constraints, and minimize environmental impacts at both new projects and existing operations. From baseline studies and permitting through remediation and long-term site care, we translate technical findings into clear next steps to help clients advance projects responsibly.
Why Work With TULLOCH?
Applied Science and Engineering for Site Realities
Focused Scope
Studies and assessments are scaled to defined risks and requirements, helping clients control effort, cost, and schedule more effectively.

Process and Methodologies
From Early Assessment to Long-Term Management
Desktop Review
Available information is reviewed to clarify potential impacts on permitting, fieldwork, schedule, cost, and project feasibility.
Baseline Field Investigations
Field teams document ecological, water, soil, groundwater, and site conditions to establish reliable baseline information.
Studies and Sampling
We complete focused surveys, assessments, sampling, and monitoring programs based on site conditions and applicable requirements.
Analysis and Guidance
We evaluate results and recommend practical options for avoidance, mitigation, remediation, management, or further investigation.
Permitting and Reporting
We prepare technical reports and submissions while coordinating requirements with agencies, reviewers, stakeholders, and project teams.
Monitoring and Stewardship
Monitoring, reporting, remediation verification, closure planning, and site care help clients manage changing conditions and long-term obligations.

Environmental Services FAQs
Useful starting information includes the site location, project type, schedule, available reports, known concerns, property history, and proposed site activities. TULLOCH can help identify information gaps and determine the appropriate next step.
Yes. Some ecological surveys must occur during specific seasons, weather conditions, or species activity periods. Early scheduling helps project teams account for these windows before they affect design, approvals, or construction.
A Phase I ESA reviews historical records, site use, and observations to identify potential environmental concerns. A Phase II ESA uses soil, groundwater, or other sampling to investigate concerns identified during the initial review.
Requirements depend on the project, excavation activities, soil destination, applicable regulations, and site conditions. Early review helps determine characterization, tracking, registry, documentation, and reuse or disposal needs.
The duration depends on permit conditions, project risks, site performance, closure requirements, and the purpose of the program. Some assignments require short construction-period monitoring, while others continue through operations, remediation, or post-closure care.
