Hudbay Minerals Inc. is contesting a federal agencyโs order to stop grading and land-clearing on a portion of its Copper World project, while itโs under a law enforcement investigation by a second federal agency over its work at the entire site in the Santa Rita Mountains south of Tucson.
The twin agency actions โ one by the U.S. Army Corps of engineers, the other by the U.S. Environmental Protection Agency โ raise questions about how long Hudbay can legally keep grading at the 4,500-acre, privately owned Copper World site on the west slope of the Santa Ritas. Theoretically, either one could lead to at least a partial shutdown there until the company once again gets a federal Clean Water Act permit to grade washes in that area โ after the Corps suspended an earlier such permit and Hudbay officially surrendered it.
The agency actions are:
The Army Corps wrote Hudbay in early January to stop all work on its Copper World site lying within the boundaries of a Clean Water Act permit that the Corps issued for the Rosemont Mine nearly three years ago but has since suspended. That permit covers some but not all of the washes on the west slope area as well as those on the original Rosemont site on the east slope. But Hudbay says it no longer needs to comply with conditions of that permit because it voluntarily surrendered it in April 2022.
The EPAโs San Francisco regional office has initiated a law enforcement investigation concerning Hudbayโs grading work for the Copper World project, an Army Corps spokeswoman told the Star. The Corps said, โEPA ... agreed to be the lead enforcement agency for investigating recent allegations of unauthorized activities by Hudbay.โ
Joshua Alexander, an EPA spokesman, declined to elaborate last week, saying, โEPA does not comment on any possible investigations.โ
EPA did send Hudbay a letter in August seeking information about whether company work at the Copper World site at least since April 2022 had placed any rock, dirt or similar material in โWaters of the U.S.โ Thatโs a federal term for washes and other water courses that have qualified for federal regulation, โand whether that work complied with the requirements of section 404 of the Clean Water Act.โ
The letter was sent under a section of the Clean Water Act thatโs aimed at determining if a legal violation has occurred of various EPA limits, including on effluent discharges and other limits. The letter asked Hudbay to send a long list of documents, containing specific information about when the work began and ended and the projectโs location, size, nature and purpose, among other things. It also sought all information regarding aquatic resources at the site, including maps, photos and diagrams.
The company replied that its analysis has shown that none of the washes in its west slope land qualify for federal regulation . It sent EPA more than 1,000 documents, agency spokesman Alexander said.
But the company objected to many of the requests, including those seeking information about fill material being places in federally protected washes, as โoverbroad and unreasonable.โ
Such requests โimproperly assume that โwaters of the United Statesโ are present on the Copper World property when no determination that (such waters) exist has been made and, more importantly, there is no credible evidence supporting such a determination.โ
โHudbay cooperated with the EPAโs request for information and provided our studies of the area and other documents to the agency in September 2022. We are confident that the site work that has been conducted did not violate the Clean Water Act,โ the company told the Star.
Company officials also say Hudbay isnโt legally bound by the stop work order. The company also says it has has halted its grading for several months, but told the Army Corps that it could resume grading washes at the site as soon as the end of February.
Hudbay noted that the Army Corps itself had in March 2021 issued its own analysis of washes for the original Rosemont Mine project, that concluded no water courses there merit having federal control over development alongside or in them. That decision covered washes on both sides of the mountain range, in cluding a utility corridor running from Sahuarita to the Rosemont site, although it didn't cover a lot of other west slope washes included in the current Copper World project where grading is now occurring.
โAs work continues on the Copper World Complex, we remain committed to protecting both the quality and quantity of the water resources in and around the project area, which includes being a net neutral water user and a zero-discharge facility,โ Hudbay said.
โA double wrong thereโ
Back in June 2022, Assistant Army Secretary Michael Connor wrote a letter to attorney Stu Gillespie, who represents three tribes that oppose the mine, saying he had determined the Corps' 2021 decision in favor of Rosemont was not valid. That was because the Corps had issued its 2021 decision without formally consulting with those tribes, including the Tohono OโOdham and Pascua-Yaqui in southern Arizona. Hudbay took issue with Connorโs decision, saying that the 2021 conclusion should under federal rules stand for 5 years, but hasnโt legally challenged it.
But in August 2022, Connor reversed himself, writing a memo saying that he was withdrawing his June 2022 finding. That was because he had already reached a similar conclusion withdrawing a similar finding he had made in June about water courses that would be graded at a Georgia-based titanium mine site owned by Twin Pines Minerals LLC. Connor said he had withdrawn his June memo because due to a setttlement agreement the Army reached with ?Twin Pines, after Twin Pines sued, challenging his earlier findinjg.
The Corps stop work order fo Hudbgy last month made no mention ofย Connor's August 2022 finding. Instead, the agency continues to push back against a second argument by Hudbay that the agency has no authority over grading in that area because the Toronto-based mining company voluntarily surrendered its Clean Water Act permit.
Environmentalists and tribal officials say, based on their own analysis of the washesโ merits, that many of them are worthy of Clean Water Act protection. They are seeking to have the federal agencies take stronger steps to halt Hudbayโs grading altogether.
โI think the evidence here is clear these are ... waters protected by the Clean Water Act, and this company is destroying the waters without a permit or in violation of a suspended permit,โ said Gillespie, of the environmental law firm EarthJustice. It represents three tribes that oppose the Copper World project โ the Tohono OโOdham, the Pascua Yaqui and the Hopi. โThereโs a double wrong there.โ
Gillespie and top tribal officials, including chairmen of all three tribes, met with Army Corps and EPA officials in Phoenix in January and early February to discuss the Hudbay grading issues in what was termed a โgovernment to government consultation.โ At the meeting, Gillespie laid out his view that the mining company is violating the Clean Water Act.
EPA, asked by the Star if it had determined whether the west slope washes merited โWaters of the U.S.โ legal status, again said, through a spokesman, โEPA does not comment on any possible investigations.โ
Copper World mining project in January, 2021, left, and January, 2023.
Clearing began in April 2022
Hudbay has said it wants to build the Copper World project on 4,500 acres of private land. In a preliminary economic analysis report last year, the company said it intends to mine copper from four open pits, including an open pit it has long planned to build on the original Rosemont Mine on the Santa Ritasโ east slope. That project has now been folded into the larger Copper World project and the pit is now called the East Pit.
Hudbay says it intends to operate in that area for 44 years, creating 500 direct, long-term jobs and about 3,000 more indirect jobs, and generate more than $3.3 billion in local, state and federal tax revenue in that time.
But the mine projectโs opponents, including the tribes and a half-dozen environmental groups, have said the mine will pump excessive amounts of groundwater from the underlying aquifer and destroy precious wildlife habitat, Some of that land, on the east slope, is known to play host to nearly a dozen federally protected species. The environmental groups include the Tucson-based Center for Biological Diversity and Save the Scenic Santa Ritas.
The original Rosemont Mine on the east slope is now on indefinite hold, thanks to unfavorable federal court rulings in 2019 that forbade Hudbay to bury its mine wastes on federal land near the original Rosemont open pit site.
This flyover shows the Santa Rita Mountainsโ west slope, where Hudbay Minerals has been grading and land-clearing since April 2022 for its planned Copper World Mining Project. Video courtesy of Center for Biological Diversity.
The company started clearing and grading on the west slope in April 2022, for what it said would be future mine tailings and waste rock disposal areas. Environmentalists and tribes sued unsuccessfully in federal court to stop the construction, and the grading continued for some time.
Until the grading work stopped, the Center for Biological Diversity said its aerial drone photos had shown the company was โtearing the hell out of that magnificent place,โ meaning the Santa Ritas, in the words of Russ McSpadden, a conservation advocate for the group. McSpadden said Hudbay โseems to have been at a marked lull in activity, as Iโve been able to see, since mid-January,โ compared to โreally intense activityโ he said he saw through the last eight months of 2022 and early 2023.
Permit surrendered by Hudbay
The Army Corpsโ stop work order stemmed from the Clean Water Act permit that the Corps approved for the Rosemont Mine in March 2019, but suspended in August of that year. The suspension was due to the federal court ruling that stopped the Rosemont Mine from being built with use of U.S. Forest Service land for mine waste disposal. The permit area also includes part of the west slope area due for mining by Copper World, including a utility corridor through which electricity and water would be delivered to the mine site from the Sahuarita area.

Last April, Hudbay wrote the Corps, to surrender the permit due to the uncertainty over its fate. U.S. District Judge James Soto accepted Hudbayโs surrender the same month, in ruling against mine opponentsโ lawsuit seeking to have the permit overturned. and the grading halted. He wrote, โthere is no longer a live case or controversy surrounding the propriety of the Corps decision, and the relief plaintiffs request is no longer available.โ
The opponents and the Corps had argued that the agency has no formal process for surrendering the permit. But Soto wrote, โIt would be illogical to read the regulations such that they would prevent a permittee from surrendering its own permit when it no longer wants it and avows that it has taken no action pursuant to it and will not do so.โ
Because of the ruling, Hudbay wrote the Corps last July that it โis not bound by the permit in any way,โ and that it no longer has to avoid working in the areas covered by the permit.
In January, however, the Corps, saying it had learned that Hudbay was doing work within the area covered by the permit, wroteย Hudbay, restating its view that no legal process exists for the company to surrender the permit, and that the Corps hasnโt decided to reinstate, modify or revoke the permit. That meant the permit remains suspended, the Corps said.
โYou are reminded that you are not authorized to do work and are ordered to stop any work within the permit area that is covered by the suspended . . . permit,โ the Corpsโ Tori White wrote Hudbay attorney Matt Bingham. White is chief of operations and regulatory matters for the Corpsโโ South Pacific Division in San Francisco.
On January 31st, Hudbay executive Javier Del Rio wrote the Corps that due to Sotoโs ruling that Hudbay had legally surrendered the permit, โthe Corps cannot legally order Copper World to stop work on its private land on the basis of the permit.โ Del Rio is vice president for Hudbayโs U.S. and South America operations.
Del Rio added Hudbay has no plans for work impacting washes covered by the Corps permit until Feb. 27, at the earliest. The company also sent the Corps a series of maps that it said show it hadnโt performed earthwork in washes inside permit areas.
Asked by the Star how it intends to proceed based on Hudbayโs response, the Corps said in an email, โWith regard to the permit, we canโt discuss any enforcement matters. We are in active discussions with Rosemont/Copper World about what work they are undertaking and plan to undertake. Weโve discussed with Hudbay a potential for doing a site visit, and they were agreeable to it.โ
Conflicting responses to agencies
But in its late September 2022 reply to EPAโs request for information about Copper World, Hudbayโs response conflicted with what it later told the Corps.
It first said that once it had formally concluded all of its research by late 2021 that determined that its west slope washes donโt meet federal standards for coming under Clean Water Act jurisdiction, Hudbay began placing fill materials in some Copper World Washes. But it continued to avoid washes in its utility corridor โ that were covered under the Clean Water Act permit.
But after surrendering that permit in April 2022 and later telling the Corps that July it would no longer avoid washes covered by the permit, โwork in those areas commenced one week later, on August 3, 2022,โ the company wrote EPA.
Earthjustice attorney Gillespie called Hudbayโs statements to the Corps and EPA โirreconcilable.โ He sent photos to the Corps last week of graded areas on the Copper World site showing construction work that the environmentalists believe, based on satellite imagery, occurred in washes along the utility corridor thatโs covered by the Clean Water Act permit.
Asked by the Star about its comment to EPA, Hudbay replied, โIt would have been more accurate to say thatโ the company lifted its restriction in August on grading inside the permit area rather than saying, โWork commenced in August.โ
Based on a recent internal review, Hudbay can confirm that none of the washes authorized for fill under the (Clean Water Act) permit have actually been filled,โ the company said.
As for the photos, the Corpsโ Tori White replied to Gillespie Friday that the agencyโs review found they were taken in areas outside the boundaries of Hudbayโs Clean Water Act permit. The Corps โwill forward this information to EPA, as they are lead investigating agency for Copper World,โ White wrote.
It would be EPAโs responsibility to determine if new alleged unauthorized activities have occurred within federally regulated waters, and whether such work requires Clean Water Act authorization, the Corps said in a statement. โIt is unlawful for Rosemont/Copper World to fill jurisdictional waters of the United States.โ
