What is a Load Letter and Why Is It Important?
When a Building decides that they want to convert their oil burning boiler to one fired on natural gas, one of the first steps in the project is to complete and submit a gas “Load Letter” to Con Edison. This Load Letter can be submitted by either authorized personnel for the building or agents engaged to work on the building’s behalf such as an engineer or contractor. The Load Letter lists and describes the existing gas burning...

Preventing Seasonal Water System Damage
Winter is fast approaching. It is a well-documented, but often misunderstood fact that water system damage can and does occur when systems are NOT IN OPERATION.  The default belief is that problems only need to be controlled while a system is under flow and transferring heat.  Not true.  Some would argue that PM treatment is easy while things are flowing.  However, the water treatment professional should worry equally as much about what might happen in...

Understanding a Cooling Tower MPP Series: Part 3
Part 3. Risk Assessment The next section required to be included in preparation of a management program and plan is the risk assessment. Naturally, this is one of the most important components of the plan as it will segregate and identify a number of factors specific to the site that will dictate risk management, and minimize risk of legionella. As required by RCNY chapter 8 the risk assessment must evaluate the following data: Any dead... Read More »
Point of Entry
Once the Ruling to move forward with a natural gas conversion is received, a” POE” or “Point of Entry” appointment needs to be requested.  The POE is that location where Con Edison, or some other Natural Gas Utility, and the contractor, determine that the new gas service will enter the building.  Multiple factors need to be evaluated to select an optimal POE location. Therefore, upon request of a POE appointment, an on-site meeting is scheduled... Read More »

Owners Representative – Typically responsible for NYC & NYS Compliance Registration/Uploads.... Read More »
Saving Money on your Facilities Water Bill
Many Pubic Water/Wastewater Providers offer “sewer abatement programs”. These programs are typically for irrigation, humidification, and cooling tower systems. The reason these programs are offered is because these systems create little or no waste stream. “Why pay a sewer charge when you are not putting anything into the sewer”. In the case of irrigation systems and humidification boilers, you will be required to install one dedicated water meter for each system. You will be charged... Read More »

Green Buildings – Green Industries
Much information has been put forth concerning the need for green, sustainable technologies to protect our planet and our indoor/outdoor environments. Unfortunately, when it comes to a conversation about chemical water treatment for HVAC and Industrial systems, some have suggested that since ‘chemicals’ are employed, the industry cannot possibly be Green. This sentiment cannot be further from the truth. In fact, the Water Treatment industry is at the very foundation of Green. Building managers, Plant... Read More »
Annual Boiler Inspection
When it comes to your annual boiler inspections, the city allows clients to submit inspection results on any given day of the calendar year (as long as submitted within 30 days of the inspection date). Upon completing the annual boiler inspection, the average companies file the results to the city regardless of what they report. This can be problematic for the client as the client would then be on the clock to resolve any defects... Read More »
