Notice of Intent to Cancel the Registrations of Nuclo Dry Granular Algaecide, Nuclo Dry Algaecide 90, Winterizing Algaecide, and Algicil Plus

Pursuant to section 6(b) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), this Notice announces EPA's intent to cancel the following pesticide registrations for simazine products used in swimming pools, hot tubs, and whirlpool baths: Nuclo Dry Granular Algaecide (EPA Reg. No. 7124-32) and Nuclo Dry Algaecide 90 (EPA Reg. No. 7124-93), produced by Alden Leeds, Inc.; and Winterizing Algaecide (EPA Reg. No. 3432-33) and Algicil Plus (EPA Reg. No. 3432-54), produced by N. Jonas Company. EPA is taking this action because it believes that the use of the products, in accordance with widespread and commonly recognized practice, generally causes unreasonable adverse effects on the environment. Specifically, EPA is concerned with potential cancer and non-cancer effects resulting from exposure to simazine in swimming pools. EPA believes that the risks from this particular simazine use exceed the benefits derived from this use. Effective the date of final cancellation, EPA will not allow further sale, distribution, or use of existing stocks of these products, as described in this Notice. Holders of existing stocks are subject to FIFRA section 6(g) reporting requirements. DATES: Requests for a hearing by a registrant must be received by the Office of the Hearing Clerk at the address given below on or before August 5, 1994, or on or before 30 days from receipt of this Notice by the registrant, whichever occurs later. Requests for a hearing by other adversely affected parties must be received by the Office of the Hearing Clerk on or before August 5, 1994.
