Janelle N. Nolan
Principal / Director of Environmental Compliance and Permitting janelle@robertson-bryan.com
 Ms. Janelle Nolan has more than 19 years of experience in environmental consulting, focused on terrestrial resources and regulatory compliance. Janelle has managed and served as principal biologist for FERC hydroelectric relicensing, Section 7 consultations, habitat conservation plans, special-status species mitigation monitoring and management plans, CEQA/NEPA documents, and wetland delineation and permitting. Janelle has in-depth knowledge and understanding of regulatory processes and permitting requirements for federal and state endangered species acts and has established working relationships with agency representatives.
Ms. Nolan has extensive experience addressing complex endangered species issues and has successfully prepared, consulted, or negotiated study plans and reports; biological assessments and biological evaluations; HCPs (traditional and low-effect); mitigation monitoring and management plans; mitigation bank evaluations; environmental impact reports, environmental assessments, environmental impact statements, constraints and opportunities reports; and training programs.
Specifically, Ms. Nolan’s biological resources experience extends to complex negotiations with agencies and stakeholders to address federally listed species issues. Janelle is the principal terrestrial biologist and technical lead for ESA consultation on hydroelectric projects in the Sierra and Sierra Nevada foothills for Southern California Edison (SCE). Janelle directed interaction between agency and public stakeholder groups for critical resource issues throughout this process. She worked with SCE maintenance and operations staff to develop implementable avoidance and protection measures to minimize adverse effects on federally listed species, while meeting SCE’s maintenance and operations objectives and requirements. Ms. Nolan specializes in developing unique approaches to determine project impacts and to develop avoidance, protection, and mitigation measures that are consistent with the level of impact. These new approaches typically are not consistent with agency guidelines; in some cases, Janelle’s unique approach becomes the new agency standard for addressing similar issues on other projects.
