Letter of Recommendation: Dave Harzinski, Plant Engineer Stoner Inc.





I received the final DEP certificates yesterday officially bringing the tank farm project to a close.

While it took over 5 years from our first contact, this project was worth the wait.


SP&ES received the largest, single PO ever issued by Stoner Inc.


These monies helped address the four pillars of engineering projects here:

  1. Safety — Unloading of all chemicals is a greatly improved design for our employees and suppliers as well as the environment.

  2. Quality — Properly configured tanks and piping reduces our risk of contamination.

  3. Productivity — Storage volume increases and flexible design will serve us well into the future.

  4. Regulatory — Entire project is NFPA, L&I and DEP compliant


The challenge of any large installation is proper planning and execution of that plan. I have received many compliments about how smooth this install went. All of the upfront effort was worthwhile as we were able to complete the entire project with zero downtime to the facility.


A simple letter cannot express the gratitude of thanks Stoner has for the work of Kirk Baker, Mark Yuko and Brent White. These three gentlemen did an outstanding job from start to finish. They were professional and responsive to all our needs and delivered a world-class project. It was a pleasure for the entire company getting to know them.

SP&ES will be a valuable supplier as we continue to grow our business. Please feel free to use us as a reference anytime.

We look forward to working with you in the future.
