Standard Codes
Better assessment of corrosion, maintenance related problems, and a new category of features and defects relating to the rehabilitation/renewal of existing sewers.

Training & Certification of Users
Every student will be assigned a certification number that will become part of any assessments that the student provides, assuming training has been completed successfully.  This can be used as a requirement by municipalities in their specifications and will insure nationwide use of the data.

Standard PACP Data Format
Includes data dictionary that defines fields, formatting, and valid entries.

Mapping Symbology Standards
Establishing color and line-type for use in mapping basic parameters such as diameter, pipe material, depth, and condition rating.

Condition Ratings
Weighting factors are used to convert the descriptive data of the PACP codes into general categories of pipe condition. This will then focus attention on sewer segments that need further evaluation/consideration for renewal or replacement.

NASSCO Master Trainer
Woodside Environmental Services

In 1995 I began a new company, Underground Camera Service, Inc., a cleaning and video inspection company. By 1997 I was managing four Cleaning/CCTV crews, 2 SSES crews and 2 manhole rehabilitation crews. My responsibilities included the day to day data collection and delivery of large CCTV projects in the Southeastern United States. This company was sold in 2011.

I was trained and certified in NASSCO PACP in 2003 and by 2004 we were providing PACP inspection data to all our clients. In 2005 I I became a PACP Trainer. I was selected in January 2019 to become a NASSCO Master Trainer, one of 5 in the country.

I began Woodside Environmental Services in 2011 as a dba, providing consulting on SSES projects, and NASSCO Certified PACP Training.

Since 2005 I have trained municipalities, engineering firms and contractors in proper cleaning and CCTV procedures as well as PACP, MACP and LACP certifications. I have performed numerous presentations to city councils, collections systems managers and engineers, promoting the benefits of PACP coding and grading for pipe evaluations and rehabilitation.

Thank you for the opportunity to provide you with this information.
