Good morning,
I am looking for examples to send my Plumbing and Electrcial Subcontractors to explain thier process for copper pipe joints and recycling the electrical wires containing lead. Neither company has had to complete this before. Our project is a renovation of a medical office building built in the 1960's.
I have material ingredient letters from our roofer and paint manufacturers to show no Lead, Cadmium or Copper. I have pasted below the complete LEED language for this credit. Any and all help with templates or wording are geatly appreciated!
Intent
To reduce the release of persistent, bioaccumulative, and toxic (PBT) chemicals associated with the life cycle of building materials.
Requirements
Specify substitutes for materials manufactured with lead and cadmium, as follows.
Lead
- For water intended for human consumption, specify and use solder and flux to connect plumbing pipe on site that meets the California AB1953 standard, which specifies that solder not contain more than 0.2% lead, and flux not more than a weighted average of 0.25% lead for wetted surfaces. The “lead free” label as defined by the Safe Drinking Water Act (SDWA)) does not provide adequate screening for the purposes of this credit because the SDWA defines “lead free” as solders and flux containing 0.2% lead or less.
- For water intended for human consumption, specify and use pipes, pipe fittings, plumbing fittings, and faucets that meet the California law AB1953 of a weighted average lead content of the wetted surface area of not more than 0.25% lead.
- Specify and use lead-free roofing and flashing.
- Specify and use electrical wire and cable with lead content less than 300 parts per million.
- Specify no use of interior or exterior paints containing lead.
- For renovation projects, ensure the removal and appropriate disposal of disconnected wires with lead stabilizers, consistent with the 2002 National Electric Code requirements.
Lead used for radiation shielding and copper used for MRI shielding are exempt.
- Specify no use of interior or exterior paints containing intentionally added cadmium.
Copper
- For copper pipe applications, reduce or eliminate joint-related sources of copper corrosion:
Thanks!

Priscilla,
We did submit and received points for this credit. We did work closely with our trade partners to have the needed documentation. We were going for silver and received Gold!!! Yay!!!!
We had letters from the manufacturers confirming products did not contain the ingredients listed above and letters from our electrician and plumber stating their products and processes did not contain lead, copper or cadmium. I cannot attach examples here but here is a list of the documentation we submitted:

Ann, did you include low voltage cabling, such as that required for lighting controls, in your electrical wire/cabling documents? We struggle with understanding the scope of the electrical wire/cabling covered by this credit and aren't sure if we need to include this type of material. Thoughts?

Michelle,
We had to replace all the electrical wiring in the building to remove the lead wires. Our electrical trade partner submitted a letter on thier letterhead stating the process used used to remove the old wire without contamination and the recycling process to an authorized recycler. They also confirmed the new cables are compliant with RoHS and lead free. With that letter they submitted they product specifications for all replacement wire and a statement for the recycler, on letterhead about the recycling process. It was certified that the old wires did not contain lead so averything was able to be recycled.
We recieved the same kids of documentation from our plumber regarding the copper pipes used for plumbing. The manufactures for the paint, insulation and sealants also provided letters verifying their products do not contain lead orcadmium.
I hope this helps. We did recieve the PBT credit fr Innovation.
