While tending my desert garden, I became a sort of citizen scientist observing the impact of rising temperatures and declining rainfall in Tucson. That convinced me that we need to do everything we can to lessen the impact of climate change. I share my journey on Sustainable Living Tucson blog. That includes what I have learned about sustainable practices like water-harvesting and clean energy. I also directed a virtual production of my play, "Regeneration: The Tucson Story" that you can find on Youtube. I am currently the lead of Sustainable Tucson's Environmental Advocacy group and a member of the Water Committee. I attend the Pima Department of Environmental Quality's Green Infrastructure planning meetings as Sustainable Tucson's Water Ambassador. I also rally my friends on social media to become active too by posting Calls to Action from my blog Desktop Activist Tucson.

Neighbors Protest Installation of TEP’s Polluting Generators

Protesting TEP’s petition to install gas-fired engines

50 people from the neighborhood showed up to protest the gas-fired engines being installed at Tucson’s Sundt Generating Station.  The Pima County Department of Environmental Quality’s (PDEQ) held a public hearing on TEP’s plan to replace two 1950s era steam units with ten natural gas-fired combustion engines. Several members of our community spoke about how carbon dioxide from the engines would speed up climate change and how that would devastate our city.

As I mentioned in a previous blog, TEP’s proposed engines are fossil-fuel based generating units that would create significant greenhouse gas emissions. According to the Pima Department of Environmental Quality, the project expects to cause an increase in emissions of carbon monoxide, particulate matter, and volatile organic compounds.

But those comments could have no impact. We were limited to commenting on how TEP’s permit meets the criteria for issuance prescribed in the Arizona Revised Statutes, Section § 49-481 of the Pima County Code.  All those important comments about climate change were disregarded because CO2 isn’t included in Pima’s code. (I know! I couldn’t believe it either!) EPA administer Scott Pruitt is working on repealing the Clean Power Plan.  (Sign a letter opposing it here.)

A few of us from Sustainable Tucson’s Environmental advocacy group and the Sierra Club spent hours combing through Pima’s code — trying to find some inconsistencies or anything we can use stop the PDEQ from issuing a permit for the RICE engines.

Quick Response Action: Register Your Opposition To The Unconstitutional Amendment To HCR 2017

by

The APS and their supporters at the Capitol are back with another proposal to subvert the initiative process and confuse voters. Late last week, HCR2017 was subject to a strike-everything amendment, offered by Senator John Kavanagh. HCR2017 would now propose a constitutional amendment virtually identical to the “Clean Energy for a Healthy Arizona” initiative, but with a loophole that would … Read more

Plan to Modernize TEP Power Plant in Tucson will Produce More Air Pollution

Tucson Electric Power is proposing to modernize the Sundt Generating Station  at 4120 E Irvington Rd. in Tucson by replacing two 1950’s era steam units with 10 natural gas-fired combustion engines. The purpose of the new engines is to ramp up more quickly and to balance the variability associated with solar and wind energy generation. But all that ramping spouts more pollution into the air than the current steam units.

TEP claims that these units are part of a larger goal for 30% renewable energy by 2030, but gas-fired engines should not be equated with clean, renewable power from wind and solar. The Reciprocating Internal Combustion Engine (“RICE”) units are fossil-fuel based generating units that would create significant greenhouse gas emissions.

According to the Pima County Department of Environmental Quality, the project expects to cause an increase in emissions of carbon monoxide, particulate matter (fine particles PM2.5 and coarse particles PM10) and volatile organic compounds.

Over a third of carbon dioxide emissions in the US are from power plants.
