1. What Do Inspectors Need To Know About BMPs? Tim Zimmerly, Terrill Lemke Los Alamos National Laboratory LA-UR-08-06656

2. Background Los Alamos National Laboratory 40 sq. mi. DOE facility High altitude –6500-7300 ft asl Semi-Arid Climate –19” annual precipitation –45% in Jul-Sept High UV LA-UR-08-06656

3. Background LA-UR-08-06656 Steep topography Mountain & high desert vegetation

4. Background Los Alamos National Laboratory Inspection Program NPDES Construction General Permit & Multi-Sector General Permit (Industrial) Sites Energy Independence & Security Act (EISA) requirements –> 5000 sq ft: maintain or restore pre-development hydrology Not an MS4 Year-round, ongoing construction –Linear projects, new facilities, D&D, environmental monitoring & remediation Over last 5 years: –Avg. 600 inspections per year LA-UR-08-06656

5. Fundamentals To establish a well-functioning inspection program: 1.Inspectors need to both identify issues and work with others as a team to solve problems. 2.The basis for a successful teamwork approach is solid technical background in BMPs. 3.Inspectors must use BMP knowledge to effectively work with designers, contractors, and owners So… LA-UR-08-06656

6. Fundamentals What do inspectors need to know about BMPs and how do they use this knowledge? –Roles & Responsibilities –Technical Background –BMP Issues –How to Interact with Others –Elements for Continued Success LA-UR-08-06656

7. Roles & Responsibilities Designer: –Develops site design and possibly SWPPP –Designs drainage features, BMPs, and stabilization measures –Works to design standards/criteria –Communicates with the contractor and possibly with the inspector through the contractor LA-UR-08-06656

8. Roles & Responsibilities Contractor: –Implements project design and SWPPP –Maintains day-to-day control of the site –Implements schedule and performs field changes –Installs and maintains BMPs –Communicates directly with the designer and inspector LA-UR-08-06656

9. Roles & Responsibilities Owner: –Plans and executes facility budget –Implements new BMPs –Maintains existing BMPs –Implements preventative maintenance program –Adapts processes to new regulations –Communicates directly with the inspector LA-UR-08-06656

10. Roles & Responsibilities Inspector: –Assesses and reports on SWPPP implementation and regulatory compliance –Identifies compliance problems in the field –Evaluates construction and post-construction BMPs –Works with contractor to solve problems and identify issues to be resolved by designer –Communicates directly with the contractor or owner and may communicate directly with designer LA-UR-08-06656

11. Working Together Designer ContractorInspector Redesign BMPs if inspection shows not effective Interact to ensure BMPs correctly implemented Communicate BMP design changes and needs All three work together to ensure proper design and effectiveness LA-UR-08-06656

12. Technical Background In-depth understanding of regulations General knowledge of hydrology Knowledge about the erodibility of soil types Understand vegetation establishment concepts How to read design drawings and details associated with the installation of BMPs Professional certification (i.e., CISEC, CMS4S) LA-UR-08-06656

13. Technical Background Knowledgeable about BMP product types and features –Function, operational limitations, and maintenance requirements for BMP categories Staying abreast of new products and technology When learning about and evaluating BMPs, inspectors need to identify and consider the following: –Where was it developed? –Under what conditions was the performance data generated? –Has this product been used or applied under the site and climate conditions similar to my locale or site? LA-UR-08-06656

14. BMP Issues LA-UR-08-06656 Designers lack knowledge and experience for adequate BMP design Designers not on site and aren’t aware of the field conditions. Maintenance requirements aren’t factored into the design Design drawings only identify final site conditions and BMPs at that phase

15. BMP Issues Contractors may have inexperience or indifference toward BMP installation and maintenance Contractors may be innovative with BMPs where no BMPs are specified or designed Designed or constructed BMPs are incorrect or inadequate LA-UR-08-06656

16. BMP Issues Design-build projects can facilitate construction activity before grading, drainage, and BMP designs are fully finalized. Temporary BMPs are specified and utilized where permanent BMPs could be used. Communication can be a challenge with both contractors and designers. LA-UR-08-06656

17. How to Interact with Others Be an effective communicator –Listen (2 ears & 1 mouth) Be able to identify deficiencies and problems with BMPs Specify or design BMPs only if you are qualified to do so LA-UR-08-06656

18. How to Interact with Others Meet with contractors and designers to help correct problems Be used as a resource and work with others as a team Understand the contractor, owner, and designer’s perspective –Listen (2 ears & 1 mouth) LA-UR-08-06656

19. How to Interact with Others What do you do when the specified BMPs are inappropriate or ineffective? Identify and report the issue Don’t redesign the BMP or mandate a specific alternative Identify the type of replacement needed Discuss the issues and alternatives with the contractor or owner and possibly the designer LA-UR-08-06656

20. How to Interact with Others LA-UR-08-06656 How can you recommend, design, or redesign BMPs? Discuss potential options with the contractor/owner Assist the contractor with the Request For Information Has long-term maintenance been considered? Work with the designer to help identify solutions. Provide product and vendor information and data

21. How to Interact with Others If asked which specific BMPs should be used, what type of information should you provide? Specific BMP information if you know how it will perform with the site climate and conditions BMP options compatible to available contractor resources and product availability. Alternative BMPs if modifications cannot be implemented within the permit timeframes. LA-UR-08-06656

22. How to Interact with Others If you have the qualifications to design BMPs, can you make recommendations to change a design without being liable? Work with the designer and contractor as they have been hired to complete their job within a set of conditions. Follow proper design protocol. Avoid designing in the field with little or no documentation. LA-UR-08-06656

23. Elements for Continued Success Qualified inspectors Training – stay current Function as part of the team Establish & practice good communication –Listening (2 ears, 1 mouth) –Writing/documentation LA-UR-08-06656

24. Summary At LANL we have learned that an inspection program is most successful when inspectors: Possess appropriate technical knowledge of BMPs Effectively interact and communicate with designers, contractors, and owners LA-UR-08-06656
